Evaluation of Antidepresant Activity and Phytochemical Screening of Plant Cordia Dichotoma.

INTRODUCTION: The traditional medicinal system of India, Ayurveda, has mentioned Cordia Dichotoma as a potential treatment for various ailments. In the current research, the extracts of Cordia Dichotoma was examined to evaluate their antidepressant potential. MATERIALS AND METHODS: Here, green leaves of Cordia Dichotoma were used to prepare chloroform, ethanol, and aqueous extracts (referred to as CdCe, CdEe, and CdAe respectively). The research focused on investigating the antidepressant effects of these extracts using behavioral models in experimental animals. Additionally, locomotor activity was assessed as part of the evaluation process. RESULTS: Immobility time was reduced with CdEe Cordia Dichotoma rFST & mTST when at 200 mg/kg and 400 mg/kg body weight. The CdAe showed reduction in immobility time in the repeated rFST) at 400 mg/kg, while in the mTST, significant effects were observed at 200 and 400 mg/kg. Regarding the chloroform extract, it only exhibited a significant reduction in immobility time in the modified Tail Suspension Test (mTST) at a low dose of 200 mg/kg. However, no noticeable change in motor dysfunction was observed with CCl4 and aqueous extracts at doses of 200 and 400 mg/kg. It is worth noting that the chloroform extract (CdCe) did lead to a significant decrease in locomotor activity at the same dosage level. Taken together, these findings suggest that extracts obtained from Cordia Dichotoma leaves may possess antidepressant properties.

Genomic evaluation for breeding and genetic management in Cordia africana, a multipurpose tropical tree species.

BACKGROUND: Planting tested forest reproductive material is crucial to ensure the increased resilience of intensively managed productive stands for timber and wood product markets under climate change scenarios. Single-step Genomic Best Linear Unbiased Prediction (ssGBLUP) analysis is a cost-effective option for using genomic tools to enhance the accuracy of predicted breeding values and genetic parameter estimation in forest tree species. Here, we tested the efficiency of ssGBLUP in a tropical multipurpose tree species, Cordia africana, by partial population genotyping. A total of 8070 trees from three breeding seedling orchards (BSOs) were phenotyped for height. We genotyped 6.1% of the phenotyped individuals with 4373 single nucleotide polymorphisms. The results of ssGBLUP were compared with pedigree-based best linear unbiased prediction (ABLUP) and genomic best linear unbiased prediction (GBLUP), based on genetic parameters, theoretical accuracy of breeding values, selection candidate ranking, genetic gain, and predictive accuracy and prediction bias. RESULTS: Genotyping a subset of the study population provided insights into the level of relatedness in BSOs, allowing better genetic management. Due to the inbreeding detected within the genotyped provenances, we estimated genetic parameters both with and without accounting for inbreeding. The ssGBLUP model showed improved performance in terms of additive genetic variance and theoretical breeding value accuracy. Similarly, ssGBLUP showed improved predictive accuracy and lower bias than the pedigree-based relationship matrix (ABLUP). CONCLUSIONS: This study of C. africana, a species in decline due to deforestation and selective logging, revealed inbreeding depression. The provenance exhibiting the highest level of inbreeding had the poorest overall performance. The use of different relationship matrices and accounting for inbreeding did not substantially affect the ranking of candidate individuals. This is the first study of this approach in a tropical multipurpose tree species, and the analysed BSOs represent the primary effort to breed C. africana.

Antioxidative and neuroprotective potential of Acorus calamus linn. and Cordia dichotoma G. Forst. In Alzheimer's type dementia in rodent.

The goal of this research study was to see how plant extracts of Acorus calamus Linn. and Cordia dichotoma G. Forst. overcome scopolamine-induced Alzheimer's type dementia in mice by activating the cholinergic system, anti-oxidant and protection of neuronal death in the brain (hippocampus region). Scopolamine (1 mg/kg i.p.) reduced mice's routine in behavioral parameters such as Morris Water Maze (MWM), Elevated Plus Maze (EPM), and also the locomotor activity. It also decreases antioxidant levels such as Reduced glutathione (GSH) and also Superoxide dismutase (SOD) but also increases the level of Acetylcholinesterase enzyme (AChE) in brain. Assessment of various behavioral, and biochemical parameters (AChE, SOD, GSH, and Nitrite level) were compared with each group. Acorus calamus (hydro-alcoholic 1:1) 600 mg/kg p.o. and the combination (Acorus calamus 600 mg/kg p.o. + Cordia dichotoma 750 mg/kg p.o.) group showed significant results as compared to Cordia dichotoma 750 mg/kg p.o.in behavioral as well as in biochemical parameters. Histological studies showed significant neuroprotection in the Acorus calamus-treated group and the combination-treated groups. In the future, the Acorus calamus and the combination are possibly helpful in the treatment of various cognitive disorders or it may be valuable to investigate the pharmacological potential of such plant extracts during the treatment of neurodegenerative disorders.

Cordia Dichotoma: A Comprehensive Review of its Phytoconstituents and Endophytic Fungal Metabolites and their Potential Anticancer Effects.

Cordia Dichotoma is a valuable medicinal plant belonging to the family Boraginaceae. It consists of several beneficial secondary metabolite components, including alkaloids, carbohydrates, flavonoids, glycosides, saponins, and tannins. Numerous studies have been conducted to assess the anticancer properties of Cordia Dichotoma on MCF-7, A-549, PC3, and HeLa cancer cell lines, primarily utilizing ethanolic extract, methanolic extract, and chloroform extract. The results of these studies have demonstrated significant effects. Furthermore, several studies have revealed the rich phytoconstituent content of Cordia Dichotoma with some significant components previously utilized by researchers to investigate the anticancer properties of specific compounds. This review discusses several of these components, including ß-sitosterol, α-amyrin, Quercitrin, Robinin, betulin, Taxifolin, and Hesperetin. Additionally, a recent study uncovered that the anticancer effect of metabolites from endophytic fungi residing on the Cordia Dichotoma plant is attributed to a property of the plant itself. This review focuses on the current state of anticancer research related to this plant and its components.

Genome Assembly of Cordia subcordata, a Coastal Protection Species in Tropical Coral Islands.

Cordia subcordata trees or shrubs, belonging to the Boraginaceae family, have strong resistance and have adapted to their habitat on a tropical coral island in China, but the lack of genome information regarding its genetic background is unclear. In this study, the genome was assembled using both short/long whole genome sequencing reads and Hi-C reads. The assembled genome was 475.3 Mb, with 468.7 Mb (99.22%) of the sequences assembled into 16 chromosomes. Repeat sequences accounted for 54.41% of the assembled genome. A total of 26,615 genes were predicted, and 25,730 genes were functionally annotated using different annotation databases. Based on its genome and the other 17 species, phylogenetic analysis using 336 single-copy genes obtained from ortholog analysis showed that C. subcordata was a sister to Coffea eugenioides, and the divergence time was estimated to be 77 MYA between the two species. Gene family evolution analysis indicated that the significantly expanded gene families were functionally related to chemical defenses against diseases. These results can provide a reference to a deeper understanding of the genetic background of C. subcordata and can be helpful in exploring its adaptation mechanism on tropical coral islands in the future.

Essential oil of Cordia curassavica (Jacq) Roem. & Schult: in vitro and in silico evaluation of effects on dengue virus replication and cytokines production / Aceite esencial de Cordia curassavica (Jacq) Roem. & Schult: evaluación in vitro e in silico del efecto sobre la replicación del virus dengue y la producción de citoquinas

The lack of effective conventional therapie s against dengue has created an interest in herbal preparations as alternative therapies. In the present study, in vitro effects of Cordia curassavica essential oil (EO) on both dengue virus replication and cytokine production were examined. Predictions of molecular interactions between EO compounds and virus and cell proteins were performed with AutoDock Vina. The EO inhibited replication of dengue virus serotypes at IC 50 < 30 µg/mL, and it reduced 87% TNF - α, 67% IL - 8 and 46% IFN - α in LPS - stimulated PBMCs. The main EO compounds were trans - ß - caryophyllene (21.4%), germacrene D (17.8%), α - copaene (16.5%), trans - ß - guaiene (8.2%), and α - pinene (6.0%). The first two compounds, δ - cadinene, α - muurolene, α - cubebene and ß - burbonene were coupled to proteins involved in the TLR - 4 cytokine effector pathway. 3,7 - Guaiadiene was coupled to the viral E and C proteins. This study demonstrates the potential of C. curassavica EO as a starting point for discovering novel therapeutic for dengue.

La falta de terapias eficaces para el dengue ha suscitado interés por preparados herbales como terapias alternativas. En el presente estudio se examinaron efectos in vitro del aceite e sencial (AE) de Cordia curassavica sobre la replicación del virus dengue y producción de citoquinas. Se realizaron predicciones de interacciones moleculares entre los compuestos del AE y proteínas virales y celulares con AutoDock Vina. El AE inhibió la rep licación de serotipos del virus a CI 50 < 30 µg/mL y redujo 87% TNF - α, 67% IL - 8 y 46% IFN - α en MNCP. Los principales compuestos del AE fueron trans - ß - cariofileno, germacreno D, α - copaeno, trans - ß - guaieno y α - pineno. Los dos primeros compuestos, el δ - cadineno, el α - muuroleno, el α - cubebeno y el ß - burboneno se acoplaron a proteínas implicadas en la vía efectora de citoquinas TLR - 4. El 3,7 - guaiadiene se acopló a las proteínas virales E y C. Este estudio demuestra el potencial del AE de C. curassavica como punto de partida para descubrir nuevas tera pias para el dengue.

Diversity, Antimicrobial, Antioxidant, and Anticancer Activity of Culturable Fungal Endophyte Communities in Cordia dichotoma.

Endophytic fungi are a significant source of secondary metabolites, which are chemical compounds with biological activities. The present study emphasizes the first-time isolation and identification of such fungi and their pharmacological activities from the medicinal plant Cordia dichotoma, which is native to Jammu, India. The Shannon Wiener diversity index revealed a wide range of fungal endophytes in root (1.992), stem (1.645), and leaf (1.46) tissues. A total of 19 endophytic fungi belonging to nine different genera were isolated from this plant and the majority belonged to the Ascomycota phylum. ITS rRNA gene sequencing was used to identify the fungal strains and they were submitted in NCBI GenBank. The most potent fungal isolate Cladosporium cladosporioides OP870014 had strong antimicrobial, antioxidant, and anticancer activity against MCF-7, HCT-116, and PC-3 cancer cell lines. The LC-MS and GC-MS analyses of the ethyl acetate extract of C. cladosporioides were examined to identify the bioactive metabolites. The major compounds of the crude extract derived from C. cladosporioides OP870014, according to GC-MS, are spiculisporic acid; dibutyl phthalate; phenylethyl alcohol; cyclohexanone, 2,3,3-trimethyl-2-3-methylbutyl; pyrrolo[1,2-a]pyrazine-1,4-dione,hexahydro-3-(phenylmethyl);2,5-piperazinedione,3,6-bis(2-methylpropyl); and heneicosane which possessed antimicrobial, anticancerous, and antioxidant activities. The findings revealed that C. dichotoma has the capacity to host a wide variety of fungal endophytes and that secondary metabolites from the endophytic fungus may be a source of alternative naturally occurring antimicrobial, antioxidant, and cytotoxic compounds.

Green synthesis of Multifunctional Zinc oxide Nanoparticles from Cordia myxa gum; and their Catalytic Reduction of Nitrophenol, Anticancer and Antimicrobial Activity.

In situ exfoliated natural polysaccharide Cordia myxa (CMX) is used to promote the utilization of zinc-oxide nanoparticles for eco-friendly catalytic hydrogenation of p-nitrophenol (p-NP) and microbial growth inhibition. Polysaccharide-mediated biosynthetic nanocomposite materials are interesting because they are cheap, green, and environmentally friendly. This study uses CMX gum as a bioreduction to produce multifunctional, environmentally friendly zinc-oxide nanocomposites (ZnO NPs). The process involves a low reaction time and temperature and utilizes CMX as a reducing and stabilizing agent. The structural, morphological, and optical properties of the CMX-ZnO nanocomposite were characterized. The biosynthetic CMX-ZnO NPs exhibited robust catalytic activity and recycling capacity for rapidly oxidizing hazardous p-NPs. The complete reduction of 4-NP to CMX-ZnO NPs in excess NaBH4 was achieved within 15 min, with recyclability and pseudo-first-order kinetics with a rate constant of 0.2571 min-1. Additionally, human colon cancer (HCT116) and 3T3L1 cell lines were remarkably sensitive to the cytotoxic effects of ZnO nanoparticles. CMX-ZnO NPs exhibited potent antibacterial properties against human pathogenic gram-positive and gram-negative bacteria (Bacillus, Salmonella, E. coli, and Pseudomonas aeruginosa) based on the zone of inhibition measured by the disc-diffusion method. The significant antibacterial activity of CMX-ZnO NPs can overcome the current limitations associated with removing water-soluble organic pollutants and microbiological contaminants for long-term environmental sustainability.

Natural cordiaquinones as strategies to inhibit the growth and biofilm formation of methicillin-sensitive and methicillin-resistant Staphylococcus spp.

AIMS: The aim of this study was to investigate the antibacterial and antibiofilm potential of cordiaquinones B, E, L, N, and O against different Staphylococci strains, in addition to analyzing in silico the observed effect. METHODS AND RESULTS: The minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) were determined according to CLSI guidelines. The inhibition of biofilm formation was investigated at sub-MICs. Atomic force microscopy (AFM) and density functional theory method were performed. The tested strains of Staphylococcus spp. were susceptible to cordiaquinones B, E, and L, among which cordiaquinone B exerted a bactericidal effect, confirmed by a bacterial growth curve study, against Staphylococcus saprophyticus. Cordiaquinones B and E showed lowest MBC values against S. saprophyticus. AFM revealed that cordiaquinone L reduced the mean cell size of S. saprophyticus. Cordiaquinones B and E inhibited the biofilm formation ability of S. aureus by ∼90%. The in silico analysis suggested that the antimicrobial activity of cordiaquinones is driven by their electron donation capability. CONCLUSIONS: Cordiaquinones inhibit the growth and biofilm formation (virulence factor) of both methicillin-sensitive and methicillin-resistant Staphylococci strains, indicating their antimicrobial potential.

Cordia oncocalyx and oncocalyxones: From the phytochemistry to the anticancer action and therapeutic benefits against chronic diseases.

Cordia oncocalyx Allemão is an endemic economically underexploited plant from Brazilian semi-arid region. Herein, we carried out a well-defined bibliographic review about the pharmacological activities of oncocalyxones from C. oncocalyx and mechanisms responsible for the biomedical properties. MeSH terms were used in the scientific databases for a narrative exploration. Technological development and bioproducts were also examined. Cordia oncocalyx is a deciduous tree of sexual reproduction rich in terpenoid quinones. Among them, oncocalyxone A, a 1,4-benzoquinone, the main compound from heartwood ethanol extracts, revealed anti-inflammatory and anti-edematogenic actions induced by carrageenan and dextran and antinociceptive potential in mice provoked by acetic acid and formalin. Oncocalyxone A inhibits platelet aggregation via activation of the soluble guanylate cyclase enzyme and blocks glycation processes. In addition to the antimicrobial effects against protozoa, fungi and bacteria and relaxation of smooth muscles, oncocalyxone A reduces mean blood pressure and glycemia in diabetic rats, decreases glomerular filtration parameters and tubular transport of electrolytes, and presents in vitro antimitotic and cytotoxic action upon different types of cancers, including resistant lung carcinoma lines. It has low oral acute toxicity (LD50 > 2000 mg/kg) and activates cellular apoptosis through the production of free radicals and interactions with DNA. However, no patents were found, which also emphasizes that Brazil, as the cradle of the main articles on C. oncocalyx, is wasting time and money. Moreover, slight systemic deleterious effects in mammals stimulate the use of oncocalyxone A and related compounds as lead constituents of safer drugs against chronic diseases.

Physicochemical and Microbiological Characteristics of Stem Bark Exudate Gum of Cordia millenii Tree in Conventional Release Tablets.

The development of a raw material into an acceptable pharmaceutical excipient involves evaluation of the physicochemical and formulation properties of the potential raw material. Results from these evaluations may serve as a guide to subsequent use of the substance. The objective of the study was to evaluate the physicochemical and microbiological properties of the stem bark gum of Cordia millenii tree in conventional release paracetamol tablets. From the physicochemical evaluations, the gum was slightly acidic and soluble in all the aqueous-based solvents, except 0.1 N HCl in which it was sparingly soluble. All the absorptive properties of the gum indicated tablet disintegrating potential for tablet formulation. The total ash of the gum was higher than that of the international standard gum arabic. Micromeritic properties of the gum indicated the need for a flow aid to improve its flowability. There were no harmful microorganisms detected in the gum. Aerobic organisms and moulds and yeast were detected within permissible limits. Tablets formulated using six different concentrations of gum dispersions as a binder were generally soft and failed the USP T80 standard of dissolution, indicating poor binding and drug releasing properties. Quality control properties of three different batches of tablets containing varying concentrations of the dry gum as a disintegrating agent were comparable to tablets containing equal concentrations of corn starch. The in vitro drug releases were similar at all-time points of drug evaluation. The gum can therefore be considered as a good disintegrant in the formulation of conventional release tablets.

The First Complete Chloroplast Genome of Cordia monoica: Structure and Comparative Analysis.

Cordia monoica is a member of the Boraginaceae family. This plant is widely distributed in tropical regions and has a great deal of medical value as well as economic importance. In the current study, the complete chloroplast (cp) genome of C. monoica was sequenced, assembled, annotated, and reported. This circular chloroplast genome had a size of 148,711 bp, with a quadripartite structure alternating between a pair of repeated inverted regions (26,897-26,901 bp) and a single copy region (77,893 bp). Among the 134 genes encoded by the cp genome, there were 89 protein-coding genes, 37 transfer RNA (tRNA) genes, and 8 ribosomal RNA (rRNA) genes. A total of 1387 tandem repeats were detected, with the hexanucleotides class making up 28 percent of the repeats. Cordia monoica has 26,303 codons in its protein-coding regions, and leucine amino acid was the most frequently encoded amino acid in contrast to cysteine. In addition, 12 of the 89 protein-coding genes were found to be under positive selection. The phyloplastomic taxonomical clustering of the Boraginaceae species provides further evidence that chloroplast genome data are reliable not only at family level but also in deciphering the phylogeny at genus level (e.g., Cordia).

Electrospun Polycaprolactone/Chitosan Nanofibers Containing Cordia myxa Fruit Extract as Potential Biocompatible Antibacterial Wound Dressings.

The goal of the current work was to create an antibacterial agent by using polycaprolactone/chitosan (PCL/CH) nanofibers loaded with Cordia myxa fruit extract (CMFE) as an antimicrobial agent for wound dressing. Several characteristics, including morphological, physicomechanical, and mechanical characteristics, surface wettability, antibacterial activity, cell viability, and in vitro drug release, were investigated. The inclusion of CMFE in PCL/CH led to increased swelling capability and maximum weight loss. The SEM images of the PCL/CH/CMFE mat showed a uniform topology free of beads and an average fiber diameter of 195.378 nm. Excellent antimicrobial activity was shown towards Escherichia coli (31.34 ± 0.42 mm), Salmonella enterica (30.27 ± 0.57 mm), Staphylococcus aureus (21.31 ± 0.17 mm), Bacillus subtilis (27.53 ± 1.53 mm), and Pseudomonas aeruginosa (22.17 ± 0.12 mm) based on the inhibition zone assay. The sample containing 5 wt% CMFE had a lower water contact angle (47 ± 3.7°), high porosity, and high swelling compared to the neat mat. The release of the 5% CMFE-loaded mat was proven to be based on anomalous non-Fickian diffusion using the Korsmeyer-Peppas model. Compared to the pure PCL membrane, the PCL-CH/CMFE membrane exhibited suitable cytocompatibility on L929 cells. In conclusion, the fabricated antimicrobial nanofibrous films demonstrated high bioavailability, with suitable properties that can be used in wound dressings.

Ixodicidal effect of extracts from Cordia boissieri, Artemisia ludoviciana and Litchi chinensis on Rhipicephalus (Boophilus) microplus (Acari: Ixodidae).

The ixodicidal activity of the methanolic extracts of Artemisia ludoviciana (Astereceae), Cordia boissieri (Boraginaceae) and Litchi chinensis (Sapindaceae) against two field populations of Rhipicephalus (Boophilus) microplus from the state of Nuevo Leon (NL) and Veracruz (VER) was evaluated. The extract of L. chinensis in the concentration of 150 mg/ml showed efficacies of 100% and 99% against engorged females and mortalities of 98% and 99% against larvae. C. boissieri in the same concentration showed efficacies of 71% and 37% against engorged adults and mortalities of 33.04% and 10.33% against larvae and A. ludoviciana had efficacies of 94% and 83% in adults and mortalities of 89.39% and 89.21% against larvae in both populations respectively. The enzymatic activity of Acetylcholinesterase (AChE), Carboxylesterase (CaE), Glutathione-S-Transferase (GST) and Alkaline Phosphatase (ALP) was measured in both populations of ticks. As a result, a significant difference between both populations was shown, being the VER population the one that exhibited a higher enzymatic activity (p ≤ 0.05). It can be concluded that the methanolic extract of the seed of L. chinensis shows potential ixodicidal activity and can be used as an alternative source of tick control, however, prior characterization, toxicity and formulation studies are necessary.

Transformation of waste seed biomass of Cordia myxa into valuable bioenergy through membrane bioreactor using green nanoparticles of indium oxide.

Depletion of non-renewable fuel has obliged researchers to seek out sustainable and environmentally friendly alternatives. Membranes have proven to be an effective technique in biofuel production for reaction, purification, and separation, with the ability to use both porous and non-porous membranes. It is demonstrated that a membrane-based sustainable and green production can result in a high degree of process intensification, whereas the recovery and repurposing of catalysts and alcohol are anticipated to increase the process economics. Therefore, in this study sustainable biodiesel was synthesized from inedible seed oil (37 wt%) of Cordia myxa using a membrane reactor. Transesterification was catalyzed by heterogenous nano-catalyst of indium oxide prepared with leaf extract of Boerhavia diffusa. Highest biodiesel yield of 95 wt% was achieved at methanol to oil molar ratio of 7:1, catalyst load 0.8 wt%, temperature 82.5 °C and time 180 min In2O3 nanoparticles exhibited reusability up to five successive transesterification rounds. The production of methyl esters was confirmed using Fourier-transform infrared spectroscopy and Nuclear Magnetic Resonance. The predominant fatty acid methyl ester detected in the biodiesel was 5, 8-octadecenoic acid. Biodiesel fuel qualities were determined to be comparable to worldwide ASTM D-6571 and EN-14214 standards. Finally, it was concluded that membrane technology can result in a highly intensified reaction process while efficient recovery of both nano catalysts and methanol increases the economics of transesterification and lead to sustainable production.

Phytochemical screening of Cordia glabrata (MART.) A.DC. extracts and its potential antioxidant, photoprotective, antimicrobial and antiviral activities / Triagem fitoquímica de extratos de Cordia glabrata (MART.) A.DC. e sua potencial atividade antioxidante, fotoprotetora, antimicrobiana e antiviral

Abstract Species of the genus Cordia have shown biological activities, such as anti-inflammatory, analgesic, antioxidant, antiviral, and antifungal activities. The species Cordia glabrata (MART) A.DC. Has no information concerning its phytochemical profile and possible biological activities. Thus, this study aimed to evaluate this profile in ethanolic extracts of young, adult and senescent leaves, as well as their antioxidant, photoprotective, antimicrobial, and virucidal potentials. Phytochemical analysis was performed by TLC (thin-layer chromatography) and showed the presence of flavonoids, tannins, and terpenes. The evaluation by UPLC-MS/MS (Ultra performance liquid chromatography - tandem mass spectrometer) evidenced the presence of caffeic (3.89 mgL-1), p-cumaric (6.13 mgL-1), and ferulic (0.58 mgL-1) acids, whilst, in GC/MS (Gas chromatography-mass spectrometry) analysis there was a greater amount of palmitic (51.17%), stearic (20.34%), linoleic (9.62%), and miristic (8.16%) fatty acids. The DPPH (2,2-Diphenyl-1-picrylhydrazyl) and ABTS+ (2′-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)) radicals were used to verify the potential antioxidant activity, observing a better activity for the leaf extract in the adult phenological stage: 54.63 ± 1.06 µgmL-1 (DPPH) and 44.21 ± 1.69 mM (ABTS). The potential photoprotective activity of the extracts was determined by spectrophotometry and the in vitro values of SPF (Sun Protection Factor) in young and adult leaves (5.47 and 5.41, respectively) showed values close to the minimum SPF of 6.0 required by ANVISA (Brazilian Health Regulatory Agency). It was not observed an antimicrobial activity for Staphylococcus aureus with a minimum inhibitory concentration of 2000 μgmL-1, however the anti-herpetic assay against the Herpes simplex virus type 2 (HSV-2) showed a potent virucidal activity at the tested concentrations with CV50 value <0.195 μgmL-1 and a Selectivity Index (SI = CC50 / CV50) greater than 448. The results obtained in this study suggest that extracts of leaves of C. glabrata in their adult phenological stage have potential antioxidant, photoprotective and virucidal activity, considering in vitro test results.

Resumo Espécies do gênero Cordia apresentam atividades biológicas, como anti-inflamatória, analgésica, antioxidante, antiviral e antifúngica. Para a espécie Cordia glabrata (MART) A.DC., ainda não existem informações sobre seu perfil fitoquímico e possíveis atividades biológicas, deste modo, o presente estudo teve como objetivo avaliar este perfil em extratos etanólicos de folhas jovens, adultas e senescentes, bem como o potencial antioxidante, fotoprotetor, antimicrobiano e virucida. A análise fitoquímica foi realizada por CCD (Cromatografia em Camada Delgada), mostrando a presença de flavonóides, taninos e terpenos. Na avaliação por CLAE EM/EM (Cromatografia Líquida de Ultra Eficiência acoplada a Espectrometria de Massas) foi evidenciado a presença dos ácidos caféico (3,89 mgL-1), p-cumárico (6,13 mgL-1) e ferúlico (0,58 mgL-1), paralelamente, na CG/EM (Cromatografia Gasosa acoplada a Espectrometria de Massas) verificou-se maior quantidade dos ácidos graxos palmítico (51,17%), esteárico (20,34%), linoléico (9,62%) e mirístico (8,16%). Os radicais DPPH (2,2-Difenil-1-picrilhidrazil) e ABTS+ (2′-Azino-bis (ácido 3-etilbenzotiazolina-6-sulfônico)) foram utilizados para verificar o potencial antioxidante, observando-se uma atividade superior para o extrato da folha em sua fase fenológica adulta: 54,63 ± 1,06 µgmL-1 (DPPH) e 44,21 ± 1,69 mM (ABTS+). A potencial atividade fotoprotetora dos extratos foi determinada espectrofotometricamente e os valores in vitro de FPS (Fator de Proteção Solar) em folhas jovens e adultas (5,47 e 5,41 respectivamente) apresentaram valores próximos ao FPS mínimo de 6,0 exigido pela ANVISA (Agência Nacional de Vigilância Sanitária). Não foi observada atividade antimicrobiana para Staphylococcus aureus sendo a concentração inibitória mínima de 2000 μgmL-1, no entanto o ensaio anti-herpético contra o vírus Herpes simplex tipo 2 (HSV-2) mostrou uma potente atividade virucida nas concentrações testadas com um valor de CV50 <0,195 μgmL-1 e um Índice de Seletividade (IS = CC50 / CV50) maior que 448. Os resultados obtidos neste estudo sugerem que extratos de folhas de C. glabrata em seu estágio fenológico adulto apresentam potencial antioxidante, fotoprotetora e virucida, considerando os resultados de testes in vitro.

Espécies do gênero Cordia apresentam atividades biológicas, como anti-inflamatória, analgésica, antioxidante, antiviral e antifúngica. Para a espécie Cordia glabrata (MART) A.DC., ainda não existem informações sobre seu perfil fitoquímico e possíveis atividades biológicas, deste modo, o presente estudo teve como objetivo avaliar este perfil em extratos etanólicos de folhas jovens, adultas e senescentes, bem como o potencial antioxidante, fotoprotetor, antimicrobiano e virucida. A análise fitoquímica foi realizada por CCD (Cromatografia em Camada Delgada), mostrando a presença de flavonóides, taninos e terpenos. Na avaliação por CLAE EM/EM (Cromatografia Líquida de Ultra Eficiência acoplada a Espectrometria de Massas) foi evidenciado a presença dos ácidos caféico (3,89 mgL-¹), p-cumárico (6,13 mgL-¹) e ferúlico (0,58 mgL-¹), paralelamente, na CG/EM (Cromatografia Gasosa acoplada a Espectrometria de Massas) verificou-se maior quantidade dos ácidos graxos palmítico (51,17%), esteárico (20,34%), linoléico (9,62%) e mirístico (8,16%). Os radicais DPPH (2,2-Difenil-1-picrilhidrazil) e ABTS+ (2′-Azino-bis (ácido 3-etilbenzotiazolina-6-sulfônico)) foram utilizados para verificar o potencial antioxidante, observando se uma atividade superior para o extrato da folha em sua fase fenológica adulta: 54,63 ± 1,06 µgmL-¹ (DPPH) e 44,21 ± 1,69 mM (ABTS+). A potencial atividade fotoprotetora dos extratos foi determinada espectrofotometricamente e os valores in vitro de FPS (Fator de Proteção Solar) em folhas jovens e adultas (5,47 e 5,41 respectivamente) apresentaram valores próximos ao FPS mínimo de 6,0 exigido pela ANVISA (Agência Nacional de Vigilância Sanitária). Não foi observada atividade antimicrobiana para Staphylococcus aureus sendo a concentração inibitória mínima de 2000 µgmL-¹, no entanto o ensaio anti-herpético contra o vírus Herpes simplex tipo 2 (HSV-2) mostrou uma potente atividade virucida nas concentrações testadas [...].

Electroanalytical Enzyme Biosensor Based on Cordia superba Enzyme Extract for the Detection of Phytomarkers in Kombucha.

Antioxidants are responsible for many beneficial health effects and are highly present in natural products, such as kombucha. Biosensors' development targeting antioxidants and phytomarkers are an active research field. This work aimed to propose a voltammetric polyphenolxidase (Cordia superba) biosensor for catechin and total phenolic compounds quantification in kombucha samples. Optimizations were performed on the biosensor of Cordia superba to improve the accuracy and selectivity, such as enzyme-substrate interaction time, analytical responses for different patterns and signal differences with the carbon paste and modified carbon paste electrode. Kombucha probiotic drink samples were fermented for 7 to 14 days at a controlled temperature (28 ± 2 °C). A linear curve was made for catechin with a range of 10.00 to 60.00 µM, with a limit of detection of 0.13 µM and limit of quantification of 0.39 µM. The biosensor proposed in this work was efficient in determining the patterns of phenolic compounds in kombucha.

Change in leaf anatomy, physiology, and essential oil of Varronia curassavicaJacq. accessions under two light conditions / Cambio en la anatomía de la hoja, fisiología y aceite esencial de accesiones de Varronia curassavica Jacq. bajo dos condiciones de luz

The aim of this study was to evaluate the effect of light on anatomy, physiology and essential oil content and composition of Varronia curassavica. They were analysed two light conditions (full sunlight and protected environment with 50% shade screen) and five accessions (VCUR-101, VCUR-102, VCUR-201, VCUR-302, VCUR-802). V. curassavica cultivated in full sun presented a greater development of the leaf blade and palisade parenchyma thickness for all accessions. Chlorophyll levels did not differ according to the two light environments. The leaf area was larger in the protected environment. The essential oil yield of the accessions ranged from 0.26 to 0.87 mL/plant in full sun and from 0.34 to 0.53 mL/plant in the protected environment. The composition of the essential oil was influenced by the light and the accession. All accessions presented (E)-caryophyllene and α-humulene. The influence of light on the evaluated variables is genotype dependent.

El objetivo de este estudio fue evaluar el efecto de la luz sobre la anatomía, fisiología, el contenido y composición de aceites esenciales de Varronia curassavica. Se analizaron dos condiciones de luz (pleno sol y ambiente protegido con 50% de pantalla de sombra) y cinco accesiones (VCUR-101, VCUR-102, VCUR-201, VCUR-302, VCUR-802). V. curassavica cultivada a pleno sol presentó mayor desarrollo del limbo foliar y espesor del parénquima en empalizada para todas las accesiones. Los niveles de clorofila no difirieron según los dos entornos de luz. El área foliar fue mayor en el ambiente protegido. El rendimiento de aceite esencial de las accesiones varió de 0,26 a 0,87 mL/planta a pleno sol y de 0,34 a0,53 mL/planta en el ambiente protegido. La composición del aceite esencial fue influenciada por la luz y la accesión. Todas las accesiones presentaron (E)-cariofileno y α-humuleno. La influencia de la luz sobre las variables evaluadas depende del genotipo.
