ABSTRACT
Background: Medical manifestations in the form of incisions, burns, and trauma will trigger a natural wound-healing process that involves complex interactions between cells. Brazilin and other secondary metabolites found in Sappan wood have numerous bioactive qualities, including anti-inflammatory, anti-cancer, and antioxidant properties. Aim: This study aimed to investigate the efficacy of Sappan wood (Caesalpinia Sappan L.) ethanol extract topically on the incision wound healing of albino rats. Methods: Twenty male rats were randomly assigned into five groups with four replications, i.e., (C-) was treated ointment-based, (C+) was treated with 10% povidone-iodine, (T1, T2, and T3 groups) were treated with Sappan wood extract concentration for 6.5%, 15%, and 30%, respectively. The treatment was topically administered to wounded areas twice a day for 15 days. Wound healing was evaluated histologically as the following parameters collagen deposition, polymorphonuclear neutrophils (PMN), angiogenesis, and fibrosis degree using H&E staining. IL-2 level was evaluated using the enzyme-linked immunosorbent assay (ELISA) method. Wound length reduction was calculated on days 8 and 15. Results: As a result, the 6.5% (T1), 15% (T2), and 30% (T3) Sappan wood extract groups were improved significantly (p < 0.05) compared to ointment-based (C-) and povidone-iodine (C+) groups on the collagen deposition, PMN, angiogenesis, fibrosis degree, and IL-2 level. In particular, the 6.5% (T1) Sappan wood extract group was highlighted significantly (p < 0.05) compared to other groups, evidenced by the improvisation of wound healing parameters and reduction of wound length on days 8 and 15. Conclusion: In conclusion, a 6.5% Sappan wood extract revealed its applicability to improve incision wound healing in albino rats.

Background: Gingivitis is an inflammation of the gums that is the initial cause of the development of periodontal disease by the activity of Nuclear Factor-kappa B (NF-κB), Interleukin-1ß (IL-1ß), Interleukin-6 (IL-6), p38, and Tumor Necrosis Factor-α (TNF-α). Unaddressed chronic inflammation can lead to persistent disturbances in other parts of the body. Brazilin is a naturally occurring plant chemical that may have antibacterial and anti-inflammatory effects. Treatment based on the natural plant compound, brazilin, is developed in the form of a topical cream for easy application. Objective: The aim is to develop the natural compound brazilin in the form of a topical cream as an anti-inflammatory agent to reduce NF-κB expression through Imunohistochemistry (IHC) methods, and the expression of pro-inflammatory genes IL-1ß, IL-6, p38, and TNF-α. Methods: Male Sprague-Dawley rats were induced with gingivitis using P. gingivalis bacteria. The observed groups included rats treated with a single application of brazilin cream and rats treated with two applications of brazilin cream. The treatment was administered for 15 days. On days 3, 6, 9, 12, and 15, anatomical wound observations and wound histology using hematoxylin-eosin and Masson's Trichrome staining were performed. NF-κB protein expression was analyzed using the IHC method. Gingival inflammation gene expression of NF-κB, IL-1ß, IL-6, p38, and TNF-α was measured using q-RTPCR. Results: Single and double applications of brazilin cream increased angiogenesis and decreased NF-κB protein expression, in addition to the IL-1ß, IL-6, p38, and TNF-α gene expressions. Conclusion: In a rat gingivitis model, Brazilin cream may function as an anti-inflammatory agent in the gingival tissue.

Synthesis of metal nanoparticles using plant extracts is environmentally friendly and of increasing interest. However, not all plant extracts can meet successfully on the synthesis. Therefore, searching for the high potential extracts that can reduce the metal salt precursor in the synthesis reaction is essential. The present study explores the synthesis of copper oxide nanoparticles (CuONPs) using Caesalpinia sappan heartwood extract. Phytochemical analysis and determination of the total phenolic content of the extract were performed before use as a reducing agent. Under the suitable synthesized condition, a color change in the color of the solutions to brown confirmed the formation of CuONPs. The obtained CuONPs were confirmed using ultraviolet-visible spectroscopy, photon correlation spectroscopy, X-ray diffraction, scanning electron microscope, energy dispersive X-ray, and Fourier transform infrared analysis. The synthesized CuONPs investigated for antioxidant, antiglycation, and antibacterial activities. CuONPs possessed antioxidant activities by quenching free radicals with an IC50 value of 63.35 µg/mL and reducing activity with an EC range of 3.19-10.27 mM/mg. CuONPs also inhibited the formation of advanced glycation end products in the bovine serum albumin/ribose model with an IC50 value of 17.05 µg/mL. In addition, CuONPs showed inhibition of human pathogens, including Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli, and prevention of biofilm formation and biofilm eradication, with maximum inhibition of approx. 75%. Our findings suggest that C. sappan extract can be used to obtain highly bioactive CuONPs for the development of certain medical devices and therapeutic agents.

Eight previously undescribed diterpenoids, caesamins A-H (1-8), were separated and identified from the seeds of Caesalpinia minax Hance. Their structures were characterized by extensive spectroscopic data and X-ray crystallographic analysis. Structurally, caesamin A (1) is the first cassane-type diterpenoid with a C23 carbon skeleton containing an unusual isopropyl. Caesamin F (6) represents the first example of cleistanthane diterpenoid from the genus Caesalpinia. Caesamins B (2) and F (6) exhibited inhibitory activity against LPS-induced nitric oxide production in RAW 264.7 macrophages with IC50 values of 45.67 ± 0.92 and 42.99 ± 0.24 µM, comparable to positive control 43.69 ± 2.62 µM of NG-Monomethyl-L-arginine. Furthermore, the chemotaxonomic significance of the isolates was discussed.

Background: Escherichia coli infection is one of the major diarrheal diseases resulting in the loss of pigs at a young age. Aim: This research investigated the antimicrobial activity of Caesalpinia sappan wood extract against E. coli infection as an antibiotic replacement. Methods: E. coli was cultured from diarrheal piglets and then used to find the minimal inhibition concentration (MIC). Caesalpinia sappan wood extract (500 mg/kg) was used for the treatment of diarrheal piglets compared to antibiotics (enrofloxacin 5 mg/kg) by oral administration. Another three groups of diarrheal piglets were used supplemented feed with 1% and 2% extract compared with commercial feed. Subsequently, E. coli enumeration, fecal shape, fecal color, and growth rate were recorded from day 1 to 7. Results: Based on the results, C. sappan wood extract could inhibit E. coli growth at a MIC of 16-34 mg/ml. The number of colonies did not significantly differ between C. sappan wood extract and enrofloxacin treatment groups. A supplemented feed with 1% and 2% C. sappan wood extract could improve the fecal shape and fecal score compared to the control group, albeit only in suckling pigs. There were significant differences from the control group on days 4, 5, 6, and 7 (p < 0.05). However, the average daily gain did not significantly differ among the three groups. Conclusion: The results indicate that C. sappan wood extract could improve diarrheal signs in suckling pigs and can be used as a replacement for antibiotics for organic pig production.

Strawberry (Fragaria x ananassa Duch.) is a highly perishable fruit whose characteristics make it susceptible to developing microorganisms. Plant extracts have been studied as an alternative to pesticides to control spoilage microorganisms, responding to the expectation of the population seeking a healthier way of life. The fungus Botrytis cinerea is a facultative pathogen of vegetables, which can affect all stages of the development of several fruits, such as the strawberry, where it causes gray rot. Trichilia catigua (catuaba), Paullinia cupana (guarana), Stryphnodendron barbatiman (barbatimão), and Caesalpinia peltophoroides (sibipiruna) are planted in the Brazilian flora and have demonstrated pharmacological properties in their extracts. This work aimed to treat strawberries with a biodegradable film containing extracts of these species to evaluate strawberry conservation. There were notable distinctions in mass loss between the extract-treated and control samples. The pH, total acidity (TA), and soluble solids parameters exhibited consistently significant means across both sets of samples. Luminosity increased over the course of days in the color parameters, with the exception of strawberries coated with guarana. The red color showed greater intensity, except for those coated with barbatimão extract. Considering the results, it is possible to conclude that the coatings used can become an alternative to enhance the conservation of strawberries.

Three undescribed cassane diterpenoids, caesalpanins D-F (1-3), and seven known ones were isolated from the seeds of Caesalpinia sappan. Structures and absolute configurations of 1-3 were elucidated based on the extensive spectroscopic analysis, single-crystal X-ray diffraction analysis, and ECD calculations. Structurally, compound 1 was the first example of 18-norcassane diterpenoid and 2 was a rare 20-norcassane diterpenoid having an unusual five-membered oxygen bridge between C-10/C-18. The anti-proliferative activity of 1, 3, and 4-10 against PANC-1 cells (pancreatic ductal adenocarcinoma cell line) was evaluated, and phanginin H (4) was found to exhibit anti-cancer activity with IC50 value of 18.13 ± 0.63 µM. Compound 4 inhibited PANC-1 cell growth by arresting the cell cycle at G2/M phase via regulation of cyclin-dependent kinases, and the self-renewal and metastasis of PANC-1 cells by suppressing cancer cell stemness. Furthermore, compound 4 induced ROS generation and subsequently activated autophagy, which was demonstrated by the formation of autophagic vacuoles and dynamic change of autophagic flux. The induced ROS accumulation resulted in AMPK activation and subsequently regulation of mTORC1 activity and ULK phosphorylation, indicating that 4 triggered autophagy through ROS/AMPK/mTORC1 pathway. These findings suggested that 4 might potentially be an autophagy inducer for the therapy of pancreatic cancer.

Tara (Caesalpinia spinosa, Leguminosae) seed germ (TSG), a by-product of tara gum (E417) extraction, has been used as a protein- and polyphenol-rich food ingredient for human and animal nutrition. Nevertheless, TSG is the alleged culprit for a recent foodborne outbreak of even severe acute illnesses that have affected hundreds of individuals in the USA, perhaps triggered by nonprotein amino acids such as baikiain. Herein, the composition of TSG has been characterized at molecular level, with a focus on proteins, phenolics, lipids, and mineral composition. TSG contains 43.4 % (w/w) proteins, tentatively identified for the first time by proteomics, and 14 % lipids, consisting of 83.6 % unsaturated fatty acids, especially linoleic acid. Ash is surprising high (6.5 %) because of an elevated concentration of P, K, Ca, and Mg. The detection of a rare earth element such as gadolinium (Gd, 1.6 mg kg-1), likely sourced from anthropogenic pollution, suggests alternative hypotheses for the origin of TSG hazards.

BACKGROUND: At present, porcine reproductive and respiratory syndrome (PRRS) caused by the PRRS virus (PRRSV) is one of the most severe epidemics impacting pig farming globally. Despite the fact that a number of studies have been conducted on potential solutions to this problem, none have proven effective. The focus of problem solving is the use of natural ingredients such as plant extracts. Popular throughout Asia, Caesalpinia sappan (CS) is a therapeutic plant that inhibits PRRSV in vitro. Therefore, this study was performed to determine the efficacy of CS extract dietary supplementation on the productive performance, antibody levels, immunological indicators, and lung pathology of PRRSV-challenged weaned pigs. A total of 32 weaned piglets (28 days old) were randomized into 4 groups and kept separately for 14 days. The treatments were organized in a 2 × 2 factorial design involving two factors: PRRSV challenge and supplementation with 1 mg/kg CS extract. The pigs in the PRRSV-challenged groups were intranasally inoculated with 2 mL of PRRSV (VR2332) containing 104 TCID50/mL, while those in the groups not challenged with PRRSV were inoculated with 2 mL of normal saline. RESULTS: In the PRRSV-challenged group (CS + PRRSV), supplementation with CS extract led to an increase in white blood cells (WBCs) on Day 7 post infection (p < 0.05) and particularly in lymphocytes on Days 7 and 14. The antibody titer was significantly greater in the CS + PRRSV group than in the PRRSV-challenged group not administered CS (PRRSV group) on Day 14 postinfection (S/P = 1.19 vs. 0.78). In addition, CS extract administration decreased the prevalence of pulmonary lesions, which were more prevalent in the PRRSV-challenged pigs that did not receive the CS extract. CONCLUSION: The findings of this study suggest that supplementation with CS extract is beneficial for increasing WBC counts, especially lymphocytes, increasing the levels of antibodies and reducing the prevalence of lung lesions in PRRSV-infected pigs.

The phytochemical investigation of the pericarps of Caesalpinia bonduc led to the isolation and identification of five new cassane-type alkaloids: caesalminines C - G (1-5) and six new diterpenoids: caesalbonducin K - P (6-11), along with seven known compounds (12-18). Compounds 1-5 were identified as a group of rare alkaloids possessing a tetracyclic cassane-type diterpenoid skeleton with a lactam D-ring instead of a typical furan or lactone moiety. The structures of 1-11 were elucidated on the basis of 1D and 2D NMR including HSQC, HMBC, COSY and NOESY, and other spectroscopic analyses. The cytotoxic activities of the isolated compounds were evaluated in the A431, A549 and U87MG cancer cell lines.

Three undescribed hybrid flavan-chalcones, caesalpinflavans D-F, and an unreported normonoterpene-chalcone heterodimer, caesalpinnone B, along with three known biflavonoids were isolated from the twigs and leaves of Caesalpinia digyna. Their structures were elucidated based on extensive spectroscopic analysis and quantum chemical calculations. Caesalpinflavan F was identiï¬ed as a bis-(hybrid flavan-chalcone), its natural occurrence was supported by HPLC-IT-TOF-MS analysis. The condensation of caesalpinflavan B with acetone was possibly a key step in the biosynthesis of caesalpinflavan F. Caesalpinnone B represents an unprecedented meroterpenoid featuring a cyclobutane central framework, which was derived from chalcone and normonoterpenoid via a key [2 + 2] cyclization reaction. Biological evaluation revealed that compounds caesalpinflavan D, oxytrodiflavanone A, and caesalpinnone B exhibited moderate cytotoxicity against HL-60, SMMC-7721, SW480, A-549 and/or MDA-MB-231 cell lines with IC50 values ranging from 8.051 ± 0.673 to 24.26 ± 0.61 µM. This study provided evidence for further research and possible utilization of C. digyna in the future.

Gels containing juca seed galactomannan (JSG) were evaluated for their potential to prevent the progression of dentin erosive wear in an in vitro study with four experimental groups (n = 9). The treatments included distilled water (DW), 0.05% stannous fluoride (121 ppm F), and 0.5% or 1% JSG. The specimens underwent a cycle (3 times/day) consisting of immersion in 1% citric acid (5 minutes), treatment (5 minutes), and artificial saliva exposure (2 hours/overnight) for 5 days. Surface changes were assessed using mechanical profilometry (wear), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS). The data were analyzed using ANOVA followed by Tukey's post-test (p < 0.05). The negative control group exhibited the highest wear (6.0 µm ± 3.5), significantly differing from the group treated with 0.05% stannous fluoride gel (p = 0.007), which showed less dentin loss. The groups treated with 0.5% and 1% JSG showed results similar to the negative control (p = 0.661; p = 0.212, respectively) and the stannous fluoride group (p = 0.103; p = 0.379, respectively). In the SEM images, the specimen treated with stannous fluoride showed obliterated tubules, while the JSG gels formed crystals on the dentin surface, as confirmed by the presence of oxygen and calcium in the EDS analysis. Although the JSG gels showed similar results to the stannous fluoride, did not exhibit superior efficacy at the tested concentrations.

Aims: it was evaluated the antioxidant effect of the ethanolic extract of Caesal-pinia ferrea bark in a model of oxidative stress induced by paracetamol (PCM). Methods: male Swiss mice were subdivided into four groups (control; PCM; PCM+extract; extract; n=8) in which a dose of paracetamol (250 mg.kg-1) was administered and after 3 hours the treatment with the extract (100 mg.kg-1/day) was administered for seven days, via gavage. Oxidative stress biomarkers were determined, such as catalase, glutathione-S-transferase, reduced gluta-thione, ascorbic acid, thiobarbituric acid reactive substances and carbonylated proteins of liver, kidneys and brain and plasma parameters through the dosage of glucose, cholesterol, triglycerides, aspartate aminotransferase and alanine aminotransferase. Results: the Caesalpinia ferrea extract was able to reverse the lipid and protein damage caused by the drug in the liver tissue and caused the same effect in the renal and brain tissues in the carbonylated proteins. The extract alone decreased liver glutathione-S-transferase and increased catalase and brain glutathione-S-transferase activity, in addition to lowering glucose and cholesterol, but without altering the triglycerides. Conclusions: it was possible to conclude that the ethanolic extract of the bark of Caesalpinia ferrea has a good antioxidant activity, probably due to dose of paracetamol in the samples investigated. However, more studies are needed for a better understanding of the effects of this extract compared to the effects found in this research
Objetivos: foi avaliado o efeito antioxidante do extrato etanólico da casca de Caesalpinia ferrea em modelo de estresse oxidativo induzido por paracetamol (acetaminofeno, PCM). Métodos: camundongos Swiss machos foram subdivididos em quatro grupos (controle; PCM; PCM+extrato; extrato; n=8) nos quais foi administrada uma dose de paracetamol (250 mg.kg-1) e após três horas foi administrado o tratamento com o extrato (100 mg.kg-1/ dia) por sete dias, via gavagem. Foram determinados biomarcadores de estresse oxidativo, como catalase, glutationa-S-transferase, glutationa reduzida, ácido ascórbico, substâncias reativas ao ácido tiobarbitúrico e proteínas carboniladas do fígado, rins e cérebro, além de parâmetros plasmáticos através da dosagem de glicose, colesterol, triglicerídeos, aspartato aminotransferase e alanina aminotransferase. Resultados: o extrato de Caesalpinia ferrea foi capaz de reverter os danos lipídicos e proteicos causados pela droga no tecido hepático, e também causou o mesmo efeito nos tecidos renal e cerebral nas proteínas carboniladas. O extrato sozinho diminuiu a atividade da glutationa-S-transferase hepática e aumentou a da catalase e glutationa-S-transferase cerebral, além de diminuir a glicose e o colesterol, mas sem alterar os triglicerídeos. Conclusões: foi possível concluir que o extrato etanólico da casca de Caesalpinia ferrea apresenta uma boa atividade antioxidante, provavelmente devido à presença de taninos, tendo em vista os danos causados pela alta dose de paracetamol nas amostras investigadas. Entretanto, mais estudos são necessários para um melhor entendimento dos efeitos deste extrato frente aos efeitos encontrados nesta pesquisa

The present study established the ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) method for simultaneous determination of the content of eight major active components in Caesalpinia decapetala and performed the quality evaluation of C. decapetala from different habitats with the chemical pattern recognition. The analysis was carried out on a Waters BEH C_(18) column(2.1 mm×100 mm, 1.7 μm) at 40 ℃, with the mobile phase of water containing 0.1% formic acid(A) and acetonitrile containing 0.1% formic acid under gradient elution, the flow rate of 0.3 mL·min~(-1), and the injection volume of 1 μL. The electrospray ionization(ESI) source in the negative mode and multiple reaction monitoring(MRM) were used for MS quantitative analysis. The content results were analyzed by the hierarchical cluster analysis(HCA) and principal component analysis(PCA) for the evaluation of the quality difference. Eight components showed good linear relationships within their respective concentration ranges(r>0.999), with the average recoveries of 96.85%-103.4% and RSD of 0.52%-2.8%. The analysis results showed that the quality of samples from different batches was different. The samples were classified into three clusters by HCA and PCA. The method is simple, sensitive, accurate, and efficient, and can be used for the quality evaluation of C. decapetala.

En conclusión, los extractos etanólicos de Caesalpinia spinosa tienen efecto anti-microbiano in vitro sobre Enterococcus faecalis, Sta-phylococcus aureus y Candida albicans. La actividad antimicrobiana del extracto es directamente propor-cional a su concentración. Los extractos de C. spinosa podrían ser utilizados como coadyuvantes en el trata-miento contra Enterococcus faecalis, Staphylococcus aureus, Candida albicans, que están relacionados con patologías orales (AU)
Antimicrobial resistance is a global public health problem. Infections with resistant microorganisms can be highly transmissible and even cause death. This fact generates great costs for patients and for health services. The objective of this work was to determine the in vitro antimicrobial effect of ethanolic extracts of Caesalpinia spinosa on the growth of Enterococcus faecalis, Staphylococcus aureus and Candida albicans. Samples of C. spinosa were collected and certified. Leaf, pod and seed extracts were obtained at concentrations of 100%, 75%, 50% and 25%. Using Kirby-Bauer, the disks were loaded with the extracts and deposited in the medium inoculated with strains of E. faecalis, S. aureus and C. albicans; together with a CP (antimicrobial), and a CN (ethanol). The plates were incubated at 370°C for 24 hours, then the inhibition halos were measured with a digital vernier. The value of the pod extract halo stands out, surpassing that of Ampicillin 10mg, over E. faecalis. The pod extract presented the greatest diameter of inhibition (19mm), the seed extract presented the lowest (1mm). ANOVA showed a statistically significant difference between the data obtained for all the extracts. In conclusion, the ethanolic extracts of Caesalpinia spinosa have an in vitro antimicrobial effect on Enterococcus faecalis, Staphylococcus aureus and Candida albicans. The antimicrobial activity of the extract is directly proportional to its concentration. C. spinosa extracts could be used as adjuvants in the treatment against Enterococcus faecalis, Staphylococcus aureus, Candida albicans, which are related to oral pathologies (AU)

In the present study, antidepressant-like activity of ethanol extract of leaves of Caesalpinia pulcherrima was evaluated in Swiss young male albino mice. Stress was induced in mice by subjecting them to unpredictable mild stress for 21 successive days. Ethanol extract of the leaves (100, 200 and 400 mg/ kg, p.o.) and fluoxetine (20 mg/kg, p.o.) were administered for 21 consecutive days to separate groups of unstressed and stressed mice. Ethanol extract (200 and 400 mg/kg) and fluoxetine significantly decreased immobility period of unstressed as well as stressed mice in tail suspension test (TST). However, the lowest dose (100 mg/kg) of the extract also significantly decreased immobility period of stressed mice in TST. The extract significantly restored reduced sucrose preference in stressed mice. There was no significant effect on locomotor activity of mice. Ethanol extract of the leaves significantly decreased plasma nitrite and corticosterone levels; brain MAO-A activity and MDA level; and increased brain reduced glutathione and catalase activity in unstressed as well as stressed mice as compared to their respective vehicle treated controls. Thus, ethanol extract of leaves of Caesalpinia pulcherrima showed significant antidepressant-like activity in unstressed and stressed mice probably through inhibition of brain MAO-Aactivity, reduction of oxidative stress and plasma corticosterone levels.

Abstract To investigate the in vitro anthelmintic efficacy of dividivi (Caesalpinia coriaria), a traditional medicinal plant used in Central America and the northern part of South America, extracts from the foliage of this plant were subjected to the egg hatching test (EHT) and larval exsheathment inhibition test (LEIT), against Haemonchus contortus. Four different extracts were evaluated: acetone-water (AW), methanol-water (MW), acetone-water-dichloromethane (AWD) and methanol-water-dichloromethane (MWD). The concentrations used for the EHT and LEIT tests ranged from 500 to 4000 µg mL-1 and six repetitions per concentration. The effective concentrations (EC50) were calculated using Probit analysis. The EC50 for EHT were 2947.0, 3347.0, 3959.6 and 4538.7 µg mL-1 for MWD, MW, AW and AWD, respectively. The EC50 for LEIT were 2883.4, 5927.4, 9876.3 and 9955.4 µg mL-1 for AWD, AW, MWD and MW, respectively. The methanol extracts were the most effective in inhibiting the hatching of eggs, while the acetone extracts showed efficacy in inhibiting larval exsheathment. This study explains the importance that C. coriaria has as a medicinal plant in Central and South American countries.
Resumo Para investigar a eficácia anti-helmíntica de Divi-divi (Caesalpinia coriaria), uma planta medicinal tradicional usada na América Central e no norte da América do Sul. Extratos das folhas dessa planta foram utilizados em testes in vitro de inibição da eclosão de ovos (EHT) e desembainhamento larvar (LEIT) de Haemonchus contortus. Quatro diferentes extratos foram avaliados: acetona-água (AW), metanol-água (MW), acetona-água-diclorometano (AWD) e metanol-água-diclorometano (MWD). Para os testes EHT e LEIT, as concentrações utilizadas variaram de 500 a 4000 µg mL-1, em seis repetições por concentração. As concentrações efetivas (EC50) foram calculadas, usando-se a análise Probit. A EC50 para EHT foram 2947,0; 3347,0; 3959,6 e 4538,7 µg mL-1 para MWD, MW, AW e AWD, respectivamente. As EC50 para LEIT foram 2883,4; 5927,4; 9876,3 e 9955,4 µg mL-1 para AWD, AW, MWD e MW, respectivamente. Os extratos de metanol foram os mais eficazes em inibir a eclosão de ovos, enquanto os extratos de acetona mostraram-se eficazes em inibir a desembainhamento larvar. Este estudo ajuda a explicar a importância da C. coriaria como planta medicinal nos países da América Central e América do Sul.

O consumo de alimentos naturais vem aumentando nos últimos anos, desta forma as bebidas mistas de frutas reúnem a possibilidade de combinação de diferentes aromas e sabores e a soma de componentes nutricionais, que podem oferecer ao consumidor propriedades funcionais ao organismo. Este trabalho teve como objetivo elaborar uma bebida mista potencialmente funcional e nutritiva de suco de limão, gengibre, chá verde e mel adicionada de espessante natural. Foram elaboradas três formulações: F1(Controle), F2 (0,2% de espessante) e F3 (0,3% de espessante). Realizou-se o tratamento térmico de pasteurização hot-Pack. Foram realizadas determinações de pH, teor de SS (ºBrix), ATT (% ácido cítrico), e antioxidante pelo método DPPH, as análises microbiológicas foram mesofilos, psicrófilos, coliformes totais e termotolerantes. Foi feita a estabilidade nos dias 1,15 e 30. Pode-se concluir que a bebida não mudou com a incorporação do espessante e não mudou durante o tempo de armazenamento.

Introduction: the inner bark of Caesalpinia ferrea (tul.) Martius (Fabacae), C. ferrea), popularly known as jucá, has been used in alternative medicine to treat wounds, bruises, asthma and chronic cough. Furthermore, the fruits of this species are used as antidiarrheals, decongestants and in healing, and their roots as antipyretics. Objective: to assess the possible genotoxic and antigenotoxic activities of the aqueous solution of the C. ferrea fruit. Methods: this study used the Ames test in Salmonella typhimurium strains and the micronucleus test in mouse bone marrow. Results: the Ames test results for the C. ferrea solution were not mutagenic in the Salmonella typhimurium TA100 strain in any of the doses tested. However, a protective effect against the action of sodium azide was shown in the TA100 strain at all the doses used. The micronucleus test indicated that the C. ferrea aqueous solution showed no mutagenic or antimutagenic effect. Conclusions: it was possible to conclude that the aqueous solution of the C. ferrea fruit showed no mutagenic effect in bacteria and mice, but an antimutagenic effect in bacteria.
