A fermented milk drink with Umbu (Spondias tuberosa) pulp and whey is effective for weight gain and re-nutrition in malnourished: An in vivo study in mice and children.

Malnutrition is considered one of the major public health problems worldwide and negatively affects the growth, development and learning of schoolchildren. This study developed and evaluated a fermented milk drink with added Umbu (Spondias tuberosa) pulp in the weight gain and renutrition of mice submitted to malnutrition by calorie restriction, and in malnourished children. The supplementation with this fermented milk drink contributed to an increase of 7.2 % in body weight, and 64.3 % in albumin, and a reduction of 35 % in cholesterol in malnourished mice. In humans, a group of nine malnourished children consumed a daily 200 mL serving of the milk drink (for 60 days). For humans, the fermented milk drink allowed an increase of 16.5 % in body weight, and 20.9 % in body mass index in malnourished children. In conclusion, fermented milk drink has a positive effect on the re-nutrition of malnourished mice and helps to improve the nutritional status of malnourished children.

Botanical, nutritional, phytochemical characteristics, and potential health benefits of murici (Byrsonima crassifolia) and taperebá (Spondias mombin): insights from animal and cell culture models.

Brazil has great biodiversity, and the Amazon biome stands out for a variety of native fruits with high economic and nutritional potential. Murici (Byrsonima crassifolia) and taperebá (Spondias mombin) are sources of vitamins, minerals, and phytochemicals with potential health benefits. Because of the bioactive potential of these Brazilian fruits, this review aims to gather the most current existing knowledge about their botanical, nutritional, and phytochemical properties, because the presence of several bioactive compounds may bring promising strategies to the prevention and treatment of several diseases. The search was conducted of the LILACS, MEDLINE, PubMed, and Science Direct databases, considering articles published between 2010 and 2023. The compiled results showed that these fruits, their leaves, and seeds have great antioxidant activity and are a good source of phytochemicals, especially phenolic compounds. In vitro and in vivo studies indicate that these bioactive compounds have several health benefits related to the prevention or treatment of diseases, including antioxidant effects; anti-inflammatory effects; and antidiabetic, antidepressant, neuroprotective, antiproliferative, anticancer, hypolipemic, cardioprotective, gastroprotective, hepatoprotective, and nephroprotective effects, and they are particularly related to the reduction of damage from oxidative stress. This review highlights the potential of these fruits as functional foods and for therapeutic purposes. However, it is recommended to conduct more studies on the identification and quantification of phytochemicals present in these fruits and studies in humans to better understand the mechanisms of action related to their effects and to understand the interaction of these compounds with the human body, as well as to prove the safety and efficacy of these compounds on health.

Flours from Spondias mombin and Spondias tuberosa seeds: Physicochemical characterization, technological properties, and antioxidant, antibacterial, and antidiabetic activities.

Yellow mombin (Spondias mombin) and Brazil plum (Spondias tuberosa) seeds are byproducts of exploiting their pulp and currently have no relevant food or industrial applications. Thus, the present study aimed to evaluate the physicochemical, technological, and functional characteristics of flours obtained from yellow mombin (YMF) and Brazil plum (BPF) residues. The flours presented a high percentage of insoluble fiber (68.8-70.2 g/100 g) and low carbohydrate (2.7-4.0 g/100 g) and caloric (91.9-95.3 kcal) values. The flours showed potential for technological application. In addition, the highest concentration of total phenolic content (31.1-50.2 mg GAE/g) was obtained with 70% acetone, which provided excellent results for antioxidant capacity evaluated by 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (81.0%-89.7%) and 2,2-diphenyl-1-picrylhydrazyl (60.6%-69.1%) radical scavenging capacity assays. Flour extracts in 70% acetone also exhibited inhibition of α-amylase (63.3%-78.8%) and amyloglucosidase (63.5%-71.0%). The antibacterial study revealed that extracts inhibited the growth of Escherichia coli, Burkholderia cepacia, and Burkholderia multivorans. Therefore, this study suggests the use of yellow mombin and Brazil plum residues for different food or industrial applications. PRACTICAL APPLICATION: The knowledge gained from this study will open a new approach to add value to yellow mombin and Brazil plum fruit seeds as sources of fiber and bioactive compounds, with promising application in the formulation of functional and nutraceutical products, benefiting both a sustainable environment and a sustainable industry.

Purification and characterization of novel isoforms of the polyphenol oxidase from Malus domestica fruit pulp.

Polyphenol oxidases (PPOs), belong to the group of oxidoreductases that are copper containing enzymes and are responsible for plant browning. PPOs are extensively distributed in plant kingdom and can oxidize wide range of aromatic compounds of industrial importance. The aim of this study was purification and characterization of PPO isoforms from the fruit pulp of Golden delicious apple. High performance liquid chromatography was used to purify the two novel isoforms of PPO and further their molecular weights (45 and 28 kDa) were determined using sodium dodecyl sulfate polyacrylamide gel electrophoresis. The purified isoforms have optimum pH (6.5), optimum temperature (40°C), the Vmax (4.45 µM/min) and Km (74.21 mM) with catechol substrate. The N-terminal microsequences of both PPO isoforms were determined using a pulse liquid protein sequencer and found to be AKITFHG (28 kDa) and APGGG (45 kDa). Polyphenol oxidases are efficiently used in the pharmaceutical, paper and pulp, textiles and food industries. Recently, the PPOs have been used for bioremediation and in the development of biosensors.

In-silico and in-vitro assessments of some fabaceae, rhamnaceae, apocynaceae, and anacardiaceae species against Mycobacterium tuberculosis H37Rv and triple-negative breast cancer cells.

Medicinal plants play a huge role in the treatment of various diseases in the Limpopo province (South Africa). Traditionally, concoctions used for treating tuberculosis and cancer are sometimes prepared from plant parts naturally occurring in the region, these include (but not limited to) Schotia brachypetala, Rauvolfia caffra, Schinus molle, Ziziphus mucronate, and Senna petersiana. In this study, the aim was to evaluate the potential antimycobacterial activity of the five medicinal plants against Mycobacterium smegmatis mc2155, Mycobacterium aurum A + , and Mycobacterium tuberculosis H37Rv, and cytotoxic activity against MDA-MB 231 triple-negative breast cancer cells. Phytochemical constituents present in R. caffra and S. molle were tentatively identified by LC-QTOF-MS/MS as these extracts showed antimycobacterial and cytotoxic activity. A rigorous Virtual Screening Workflow (VSW) of the tentatively identified phytocompounds was then employed to identify potential inhibitor/s of M. tuberculosis pantothenate kinase (PanK). Molecular dynamics simulations and post-MM-GBSA free energy calculations were used to determine the potential mode of action and selectivity of selected phytocompounds. The results showed that plant crude extracts generally exhibited poor antimycobacterial activity, except for R. caffra and S. molle which exhibited average efficacy against M. tuberculosis H37Rv with minimum inhibitory concentrations between 0.25-0.125 mg/mL. Only one compound with a favourable ADME profile, namely, norajmaline was returned from the VSW. Norajmaline exhibited a docking score of -7.47 kcal/mol, while, pre-MM-GBSA calculation revealed binding free energy to be -37.64 kcal/mol. All plant extracts exhibited a 50% inhibitory concentration (IC50) of < 30 µg/mL against MDA-MB 231 cells. Flow cytometry analysis of treated MDA-MB 231 cells showed that the dichloromethane extracts from S. petersiana, Z. mucronate, and ethyl acetate extracts from R. caffra and S. molle induced higher levels of apoptosis than cisplatin. It was concluded that norajmaline could emerge as a potential antimycobacterial lead compound. Validation of the antimycobacterial activity of norajmaline will need to be performed in vitro and in vivo before chemical modifications to enhance potency and efficacy are done. S. petersiana, Z. mucronate, R.caffra and S. molle possess strong potential as key contributors in developing new and effective treatments for triple-negative breast cancer in light of the urgent requirement for innovative therapeutic solutions.

Effect of extraction methods on phytochemical constituents and antioxidant activity of de-kernelled Sclerocarya birrea seeds.

BACKGROUND: Marula (Sclerocarya birrea) is an indigenous African fruit-bearing tree with many commercial uses; however, de-kernelled seeds generated from marula fruit-processing are wasted. The phytochemical constituents of de-kernelled marula seeds have not been investigated previously and its extract/tea may potentially serve as a promising source of antioxidants and phytochemicals. This study aimed to investigate the effect of different extraction methods (maceration and decoction) on the recovery of phenolic compounds, sugars, organic acids, and antioxidants from de-kernelled marula seeds. RESULTS: Extracts produced from decoction for 30 min contained the highest phenolic content (2253.93 ± 25.72 mg gallic acid equivalent kg-1 extract), flavonoid content (1020.99 ± 23.90 mg rutin equivalent kg-1 extract), as well as combined sugars and organic acids (1884.03 mg kg-1 extract). Fourier-transform infrared spectroscopy analysis confirmed the presence of functional groups typically present in phenolic compounds, sugars, and organic acids in the extracts obtained from decoction. CONCLUSION: The characterization revealed that decoction extraction increased solubility, variety, and yield of phytochemical and antioxidant compounds recovered from de-kernelled marula seeds. The highest concentrations of phytochemicals were obtained using the decoction method. This study may therefore pave the way for extract composition and future utilization of de-kernelled marula seeds in the food industry. © 2023 Society of Chemical Industry.

Characterisation of Sclerocarya birrea (marula) seed oil and investigation of the geographical origin by applying similarity calculations, differential NMR and hierarchical cluster analysis.

INTRODUCTION: The marula fruit is an important indigenous African fruit since various commercial products are produced from the pulp and the seed oil. The increased demand requires methods for authentication, quality control and determination of geographical origin. OBJECTIVE: The study aimed to establish a fast and reliable method for characterisation and authentication of marula seed oil. Furthermore, to identify marker compounds that can distinguish marula seed oils from other commercial oils and indicate regional differences. MATERIALS AND METHODS: Metabolic profiling of 44 commercial marula seed oils was performed using proton nuclear magnetic resonance (1 H NMR). For rapid classification similarity calculations were compared with principal component analysis. Differential NMR was used to determine marker compounds. RESULTS: Marula seed oil was found to be similar to macadamia and olive oils and was distinguished from these oils by the detection of minor components. Marula seed oil is differentiated from the other two oils by the absence of α-linolenic acid, relatively high levels of monoglycerides and diglycerides, and an approximately 1:1 ratio of 1,2- and 1,3-diglycerides. When comparing marula seed oils from various regions using hierarchical cluster analysis, clustering of the marula seed oils from Namibia and Zimbabwe was observed and was related to the quantities of linoleic acid and monoglycerides and diglycerides. Some samples displayed deviations in their composition which might indicate adulteration or contamination during the production process. CONCLUSION: The study demonstrates the potential of NMR as a tool in the quality control of marula seed oil. This technique requires very little sample preparation, circumvents derivatisation of the oil components with fast run-times. In addition, samples with chemical profiles that differ from the general signature profile can easily be identified.

Structural patterns of Lepidoptera galls and the case of Andescecidium parrai (Cecidosidae) galls on Schinus polygama (Anacardiaceae).

Gall anatomical and metabolic peculiarities are determined by the feeding habit of the gall inducer, but develop under the constraints of the host plants. The chewing habit of the Lepidoptera larvae imposes a high impact on the host plant cells, and supposedly drives peculiar structural and histochemical patterns. So, our starting point was the search of such patterns in literature, and the test of these traits on the Andescecidium parrai (Cecidosidae)-Schinus polygama (Anacardiaceae) system, as a case study in Chilean flora. The literature on the structure of lepidopteran galls in the temperate and tropical regions comprises 13 works, describing stems as the most frequent host organs, followed by leaves, buds, and flowers. As common structural traits of Lepidoptera galls, the literature converge in describing the processes of cell hypertrophy and hyperplasia, resulting in a variable number of common storage parenchyma layers, interspersed by the redifferentiated sclerenchyma, vascular, and typical nutritive cells around the larval chamber. These nutritive cells accumulate lipids and proteins, which support the lepidopteran larvae nutrition. As expected, the A. parrai galls follow the patterns herein described for the lepidoptera-induced galls, but with peculiarities associated with its host organ. Even though the Lepidoptera galls have destructive mouthparts and can induce large and complex galls, they cannot alter important conservative features of their hosts' organs.

Isolation and characterization of natural inhibitors of post-proline specific peptidases from the leaves of Cotinus coggygria Scop.

ETHNOPHARMACOLOGICAL RELEVANCE: Cotinus coggygria has a number of applications in traditional medicine most of which are connected with its anti-inflammatory and anti-oxidant properties. Since inflammation and oxidative stress are recognized as triggering factors for cancer, anti-cancer activity has also been documented and the possible mechanisms of this activity are under investigation. Important components of C. coggygria extracts are shown to be hydrolysable gallotannins of which pentagalloyl-O-glucose has been studied in details. This compound inhibits various enzymes including prolyl oligopeptidase which is involved in tumorigenesis and tumour growth. According to our pilot studies, oligo-O-galloylglucoses with more than five galloyl residues are also presented in the herb of Bulgarian origin, but their activities have not been examined. AIM OF THE STUDY: To establish an extraction method by which it is possible to concentrate high molecular hydrolysable gallotannins from dried leaves of Cotinus coggygria and to determine their inhibitory properties towards prolyl oligopeptidase and fibroblast activation protein α. MATERIALS AND METHODS: Dried leaves of C. coggygria were extracted using different solvents in single-phase or biphasic systems under various extraction conditions. Main compounds of the extracts were identified by using high performance liquid chromatography and liquid chromatography - high resolution mass spectrometry. The extracts' inhibitory properties towards prolyl oligopeptidase and fibroblast activation protein α were studied on recombinant human enzymes by enzyme kinetic analyses using a fluorogenic substrate. RESULTS: Ethyl acetate/water (pH 3.0) extraction of dried plant leaves proved to be the most efficient method for isolation of high molecular hydrolysable gallotannins which can be further concentrated by precipitation of dicyclohexylammonium salts in ethyl acetate. The main components of those extracts were oligo-O-galloyl glucoses with more than five gallic acid residues. They were shown to inhibit both enzymes studied but were about 30 times more effective inhibitors of prolyl oligopeptidase. CONCLUSIONS: C. coggygria from Bulgarian origin is shown to possess a substantial quantity of oligo-O-galloyl glucoses with more than five gallic acid residues which has not been described thus far in the same herb from other sources. An extraction method useable for concentrating those compounds is established. They are found to inhibit prolyl oligopeptidase with a very good selectivity to fibroblast activation protein α. The previously described antitumor activity of this plant may be at least in part due to the inhibition of the above enzymes which has been shown to participate in the genesis and development of various types of tumors.

Antiproliferative activity of compounds isolated from the root bark of Lannea acida in multiple myeloma cell lines.

Lannea acida A. Rich. is a native plant of West Africa used in traditional medicine against diarrhea, dysentery, rheumatism, and women infertility. Eleven compounds were isolated from the dichloromethane root bark extract using various chromatographic techniques. Among those, nine compounds have not been previously reported, i.e. one cardanol derivative, two alkenyl 5-hydroxycyclohex-2-en-1-ones, three alkenyl cyclohex-4-ene-1,3-diols, two alkenyl 7-oxabicyclo[4.1.0]hept-4-en-3-ols, and one alkenyl 4,5-dihydroxycyclohex-2-en-1-one, together with two known cardanols. The structure of the compounds was elucidated using NMR, HRESIMS, ECD, IR, and UV. Their antiproliferative activity was evaluated in three multiple myeloma cell lines: RPMI 8226, MM.1S, and MM.1R. Two compounds showed activity in all cell lines with IC50 values < 5 µM. Further investigations are needed to understand the mechanism of action.

Cotinus coggygria Scop. Attenuates Acetic Acid-Induced Colitis in Rats by Regulation of Inflammatory Mediators.

In traditional medicine, many medicinal plants are used in the treatment of various diseases caused by inflammation. The objective of the present study is to elucidate for the first time the effects of Cotinus coggygria (CC) ethanol extract (CCE) on colonic structure and inflammation of acetic acid-induced ulcerative colitis in rats. Colonic damage was assessed using disease activity index score, enzyme-linked immunosorbent assay, and hematoxylin-eosin staining. Also, in vitro antioxidant activity of CCE was investigated by ABTS methods. Total phytochemical content of CCE was measured spectroscopically. Acetic acid caused colonic damage according to disease activity index and macroscopic scoring. CCE significantly reversed these damages. While the levels of proinflammatory cytokines TNF-alpha, IL-1beta, IL-6, and TGF-1beta increased in tissue with UC, IL-10 level decreased. CCE increased inflammatory cytokine levels to values close to the sham group. At the same time, while markers indicating disease severity such as VEGF, COX-2, PGE2, and 8-OHdG indicated the disease in the colitis group, these values returned to normal with CCE. Histological research results support biochemical analysis. CCE exhibited significant antioxidant against ABTS radical. Also, CCE was found to have a high content of total polyphenolic compounds. These findings provide evidence that CCE might be benefit as a promising novel therapy in the treatment of UC in humans due to high polyphenol content and justify the use of CC in folkloric medicine for treatment of inflamed diseases.

Olfactory Responses of Anastrepha obliqua (Diptera: Tephritidae) to Mango Fruits as Influenced by Cultivar and Ripeness Stages.

Anastrepha obliqua Macquart (Diptera: Tephritidae) is a polyphagous species with hog plums (Spondias spp.) (Sapindales: Anacardiaceae) and mangoes (Mangifera indica L.) (Sapindales: Anacardiaceae) as primary host fruits. In this study, the olfactory preference of A. obliqua for three stages of ripeness of two mango cultivars ('Coche' and 'Ataulfo') was investigated. The female flies were more attracted to ripe 'Coche' fruits compared to those ripe 'Ataulfo'. Further, they were more attracted to the 'Coche' half-ripe and ripe fruits than to the unripe ones, but they did not discriminate among the stages of ripeness of 'Ataulfo' fruits. The male flies did not show preference for any specific mango cultivars or ripeness stage tested. Four compounds from ripe 'Coche' mangoes, and two from ripe 'Ataulfo' fruits were identified using coupled gas chromatography-electroantennographic (GC-EAD) recording and gas chromatography-mass spectrometry (GC-MS) analysis. 'Coche' mango volatiles eliciting responses from the female antennae were ethyl butyrate, ethyl hexanoate, ethyl heptanoate, and ethyl octanoate. The two 'Ataulfo' mango volatiles were identified as 3-carene and ethyl octanoate. These compounds were absent in unripe mangoes of both cultivars. Synthetic blends of these compounds were attractive to females as mango extracts in field cage tests. Our results suggest that the olfactory preference of A. obliqua for attractive hosts is based on the presence or absence of the compounds associated with fruit maturity.

Geographical variation in the chemical composition, anti-inflammatory activity of the essential oil, micromorphology and histochemistry of Schinus terebinthifolia Raddi.

ETHNOPHARMACOLOGICAL RELEVANCE: Schinus terebinthifolia Raddi (Anacardiaceae) is rich in essential oil, distinguished by a predominance of monoterpenes and sesquiterpenes, it being widely used in traditional medicine for the treatment of inflammations. AIM OF STUDY: This study's objective was to investigate the chemical composition of the essential oil of S. terebinthifolia (EOST) collected in six states of Brazil, evaluate its anti-inflammatory effects in mice, and analyze the histochemistry and micromorphology of leaves and stems. MATERIALS AND METHODS: Aerial parts of S. terebinthifolia were collected in six states of Brazil, and the essential oil was extracted by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS). The histochemistry and micromorphology of leaves and stems were performed using standard reagents, light and field emission scanning electron microscopy, beyond energy-dispersive X-ray spectroscopy. The EOST were evaluated for anti-inflammatory activity and hyperalgesia using the carrageenan-induced paw edema methodology. RESULTS: The EOST showed variation across the six states in its yield (0.40%-0.86%) and chemical composition: hydrocarbon monoterpenes (28.76%-47.73%), sesquiterpenes, (31.43%-41.76%), oxygenated monoterpenes (14.31%-19.57%), and oxygenated sesquiterpenes (4.87%-14.38%). Both α-pinene and limonene were predominant constituents of essential in five regions, except for one state where α-phellandrene and limonene were the dominant components. A comprehensive description of the leaf and stem micromorphology and histochemistry was performed. In the in vivo testing, all EOST samples exerted antiedematogenic and anti-hyperalgesic effects, when tested in a carrageenan-induced paw inflammation (mechanical and thermal hyperalgesia) model with oral doses of 30 mg/kg. CONCLUSION: Our results indicate that the EOST samples collected in six Brazilian states differed in their chemical composition but not their anti-inflammatory and antihyperalgesic effects, which was correlated with the synergistic effect of its components, collaborating the etnhopharmacologycal use of this plant due to its an anti-inflammatory effect. Also, micromorphology and histochemistry of leaves and stems presented in this study provide anatomical and microchemical information, which aids species identification.

Cytotoxic effect of Cotinus coggygria extract on Hep3B cancer cell line.

Cotinus coggygria Scop. is a medicinal plant which contains a variety of precious phytochemical compounds applicable in traditional medicine. The aim of this study is to investigate the cytotoxic effect of Cotinus coggygria extract on Hep3B cancer cells. The cytotoxic effect was measured by MTT assay. Based on IC50 values, the C. coggygria leaf extract showed cytotoxic effect on Hep3B cancer cells, which was found better at 24 h (IC50 = 3.642) then at 48 h (IC50 = 3.956). Also, the dose of C. coggygria extract showed negative correlation (p < 0.05) with cell viability of 24 h and 48 h and positive correlation (p < 0.05) with cytotoxic effect of 24 h and 48 h. The cytotoxic effects were concentration-time dependent. According to our study, C. coggygria extract had protective effect at 24 h on AML12 cell line and cytotoxic effect on the Hep3B cancer cell line, where it indicates that it may have an antitumorigenic effect.

Optimized method for dna extraction and PCR amplification in aroeira tree

Molecular markers are important tools in the characterization of plant genetic diversity and can provide support for conservation strategies for endangered populations. The different molecular techniques involve the evaluation of many individuals; therefore, it is crucial to have fast, efficient, and inexpensive methods for DNA extraction. Given the importance of the Aroeira (Myracrodruon urundeuva Fr. All.) it is pertinent to optimize a protocol that allows the obtainment of intact and pure DNA, aiming to assist conservation strategies for this species that is threatened with extinction. Thus, this study aimed to compare five DNA extraction methods: Dellaporta et al. (1983), Doyle and Doyle (1987) modified, Ferreira and Grattapaglia (1995), Romano and Brasileiro (2015), and Khanuja et al. (1999) and optimize the most efficient protocol for M. urundeuva. The modified DNA extraction protocol proposed by Doyle and Doyle (1987), using 100 mg of leaf tissue and 6 µl of ß-mercaptoethanol was the protocol that presented the sharpest bands after DNA electrophoresis and after the reactions of amplification employing Polymerase Chain Reaction (PCR). Therefore, it is suggested to use the protocol described by Doyle and Doyle (1987) modified for the extraction of DNA from young M. urundeuva leaves to carry out techniques involving molecular markers.

Ameliorative Effect of Bouea macrophylla Griffth Seed Extract Against Bacteria-Induced Acne Inflammation: in vitro study.

Currently, bioactive compounds derived from nature have been thought to be promising anti-acne substances owing to the variety of potential biological effects. This study aimed to evaluate the ameliorative effect of Bouea macrophylla Griffth seed extract against bacteria-induced acne inflammation for the first time in terms of antibacterial effects against acne-inducing bacteria, anti-inflammatory, and antioxidant properties. Initially, extracting procedures were optimized and five different extracts were obtained. Considering their antibacterial activities against Cutibacterium acnes, Staphylococcus aureus, and Staphylococcus epidermidis, ethanolic and ethyl acetate fractions exerted a notable effect which were highly superior above those of polyphenol standards. Additionally, these two extracts presented outstanding antioxidant capacities in terms of DPPH and ABTS radicals scavenging effects, reducing power, and inhibitory effect on lipid peroxidation which also play a role in the exacerbation of acne inflammation. Besides, inhibition on lipid peroxidation and reducing power of ethanolic fraction were significantly (p<0.05) better than those of ethyl acetate fraction which was corresponding to their phenolic and ellagic acid contents. However, flavonoids found in ethyl acetate fraction might play an important role in its potentials. After that, the anti-inflammatory effects of the extracts were elucidated by means of inhibition on nitric oxide production from LPS-induced RAW 264.7 cell lines at which the effects of both extracts were dosedependency. Taken together, our findings have apparently proven that B. macrophylla seed extracts exerted a variety of potential properties including antioxidation, anti-acne-inducing bacteria, and anti-inflammatory effects which could serve as a promising anti-acne agent for cosmeceutical applications.

Entomopathogenic fungi and Schinus molle essential oil: The combination of two eco-friendly agents against Aedes aegypti larvae.

Aedes aegypti transmits arbovirus, which is a public health concern. Certain filamentous fungi have the potential to control the disease. Here, the effects of Metarhizium anisopliae s.l. CG 153, Beauveria bassiana s.l. CG 206 and Schinus molle L. were investigated against Aedes aegypti larvae. In addition, the effect of essential oil on fungal development was analyzed. Fungal germination was assessed after combination with essential oil at 0.0025 %, 0.0075 %, 0.005 %, or 0.01 %; all of the oil concentrations affected germination except 0.0025 % (v/v). Larvae were exposed to 0.0025 %, 0.0075 %, 0.005 %, or 0.01 % of the essential oil or Tween 80 at 0.01 %; however, only the essential oil at 0.0025 % achieved similar results as the control. Larvae were exposed to fungi at 107 conidia mL-1 alone or in combination with the essential oil at 0.0025 %. Regardless of the combination, M. anisopliae reduced the median survival time of mosquitoes more than B. bassiana. The cumulative survival of mosquitoes exposed to M. anisopliae alone or in combination with essential oil was 7.5 % and 2 %, respectively, and for B. bassiana, it was 75 % and 71 %, respectively. M. anisopliae + essential oil had a synergistic effect against larvae, whereas B. bassiana + essential oil was antagonistic. Scanning and transmission electron microscopy, and histopathology confirmed that the interaction of M. anisopliae was through the gut and hemocoel. In contrast, the mosquito's gut was the main route for invasion by B. bassiana. Results from gas chromatography studies demonstrated sabinene and bicyclogermacrene as the main compounds of S. molle, and the in-silico investigation found evidence that both compounds affect a wide range of biological activity. For the first time, we demonstrated the potential of S. molle and its interaction with both fungal strains against A. aegypti larvae. Moreover, for the first time, we reported that S. molle might be responsible for significant changes in larval physiology. This study provides new insights into host-pathogen interplay and contributes to a better understanding of pathogenesis in mosquitoes, which have significant consequences for biological control strategies.

Schinus terebinthifolia Raddi leaf lectin is an antiangiogenic agent for Coturnix japonica embryos.

Angiogenesis (budding of new blood vessels) is involved in several processes, including the development of embryos and growth of tumors. Schinus terebinthifolia leaves express an antitumor lectin (SteLL). This work hypothesized that SteLL can interfere with the formation of a vascular network from preexisting vessels. To test this hypothesis, the effect of SteLL on the angiogenesis process was assessed using an in vivo model of yolk sac membrane of Coturnix japonica embryos. SteLL was isolated with purification factor of 46.6. As expected, polyacrylamide gel electrophoresis (PAGE) for native basic proteins confirmed the homogeneity and PAGE in presence of dodecyl sodium sulphate revealed a single 14-kDa polypeptide band. The fractal analysis by box counting and information dimension measurements indicated that SteLL at 1.35 mg/mL significantly decreased by ca. 12% the angiogenesis within the C. japonica yolk sac membrane regarding the control. The inhibition of the vascular network formation in the yolk sac membrane resulted in decreased blood supply to the embryos. Consequently, the area of embryos was significantly reduced by 9.2% regarding the control, which corroborated with the antiangiogenic activity of SteLL. The findings implicate SteLL as an antiangiogenic agent and add to the panel of biological activities of this lectin.

Insecticidal activity of the essential oil of Schinus areira against Rhipibruchus picturatus (F.) (Coleoptera: Bruchinae), and its inhibitory effects on acetylcholinesterase.

During the storage of Prosopis alba pods, substantial quantitative and qualitative losses were observed. One of the main factors is the seed beetle Rhipibruchus picturatus. A key strategy to develop new pest control management is the use of essential oils (EOs) due they are efficient, less toxic, and less persistent in the environment compared to synthetic pesticides. In this context, seeds and leaves of Schinus areira L. (Anacardiaceae) EOs and Citrus spp. EO were studied in the present work. In the leaves of S. areira EO, 1-epi-cadinol, sesquiterpenoid alcohol, was the major compound. On the other hand, the main compounds of the EO extracted from S. areira seeds are the monoterpenes sabinene, and α-pinene. Finally, in the Citrus EO, limonene is the principal component. The three EOs obtained exhibited insecticidal activity against R. picturatus, being the first report of the use of EOs against this insect pest. The best insecticidal results were obtained with the leaves of S. areira EO. Moreover, this EO inhibits the acetylcholinesterase enzyme in vitro assays. Molecular docking studies on acetylcholinesterase (AChE) suggest that the main components of the leaves of S, areira EOs, bind to the active site of the enzyme, in good agreement with in vitro competitive inhibition against AChE observed for this EO. The data obtained demonstrate the potential use of Schinus areira EOs in the development of new storage pest control strategies.
