Several species of the Myrcia genus have been used in folk medicine to treat diabetes. Therefore, the aim of this work was to investigate the inhibitory activity of α-glucosidase and pancreatic lipase in the crude extract (EBF) and in the ethyl acetate fraction (FFA) of Myrcia hatschbachii, as well as to identify isolated phenolic compounds and to evaluate the antioxidant property and preliminary in vitro toxicity against Artemia salina. EBF (IC50: 3.21 μg/mL) and FFA (IC50: 1.14 μg/mL) showed inhibitory activity superior to acarbose (IC50: 193.65 μg/mL). In addition, they showed inhibitory effects of pancreatic lipase (IC50: 556.58 μg/mL for EBF and 532.68 μg/mL for FFA), antioxidant potential, absence of preliminary toxicity and presence of gallic andellagic acids in FFA. The relevant results in the inhibition of α-glucosidase and pancreatic lipase motivate new studies for the development of herbal medicines that assist in the treatment of diabetic patients.

Herbal medicine has played a leading role in the health systems of many traditional societies. The main objective is to characterize an aspect of the natural and culturalheritage of a protected area of the town of La Calera, through the documentation of medicinal plants of the Bamba Water and Recreational Nature Reserve (RNHRB), in the province of Córdoba, Argentina. Methodologies of social and natural sciences, typical of ethnoecological approaches, were combined, complementing with qualitative and quantitative analyzes. A total of 221 uses corresponding to 137 medicinal species were documented. The most relevant families in terms of quantity of species and uses are Asteraceae, Fabaceae and Lamiaceae. In all cases the native / wild status predominates. Applications associated with gastrointestinal conditions are the most frequent, followed by dermatological, pneumonological, infectological and nephrological. It is concluded that herbal medicine in protected areas provides valuable information and efforts for the conservation of biocultural heritage in intangible rural areas with urbanized spaces, as well as for the potencial knowledge and use of resources by small local producers.

In this study, against streptozotocin (STZ) induced diapetic nephropathy (DN); it is aimed to investigate the use of thymoquinone (TQ) and β-aminoisobutyric acid (BAIBA) and to compare the effects of these agents. With randomselection of 35 male rats, five groups (seven rats in each group) were constituted as follows: Control, STZ, STZ + TQ, STZ + BAIBA, STZ + TQ + BAIBA. In the STZ group; body weight, glutathione (GSH) and insulin levels decreased, relative kidney weight, malondialdehyde (MDA), glucose, blood urea nitrogen (BUN) and creatinine (Cr) levels were increased. Also, in kidney tissue; histopathological changes (such as thickening of the capsular, glomerular and tubular basement membranes, increased mesangial matrix amount, increased cytoplasmic vacuolization in some of the tubular epithelial cells, increased tumor necrosis factor-alpha (TNF-α) expression, and inflammatory cell infiltrations in interstitial tissue) were detected. It was observed that these changes occurring after diabetes mellitus (DM) reversed significantly in TQ, BAIBA and TQ + BAIBA groups.

To explore a new underlying molecular mechanism of Huangkui Extract Powder (HKEP) in the alleviation of diabetic nephropathy (DN). Murine immortalized podocytes were divided into (i) normal glucose (NG, 5.6 mM), (ii) NG + HKEP (0.45 g/L), (iii) HG, and (iv) HG + HKEP (0.45 g/L) groups. MTT assay and flow cytometry were used to detect the podocyte proliferation, apoptosis and cell cycle. Cell viability was inhibited, and apoptosis increased in (iii) HG group compared with (i) NG group (p<0.05). mRNA and protein expression of nephrin and podocin significantly decreased in (iii) HG group compared with (i) NG group (p<0.05). When compared with (iii) HG group, (iv) HG + HKEP group had higher cell viability, lower apoptotic rate and higher mRNA and protein expression of nephrin and podocin (p<0.05). HKEP can attenuate HG-induced podocyte damage, which may be one of the mechanisms of HKEP for attenuating DN.

We aimed to investigate the effects of Calendula officinalis and Echinacea purpurea extracts in terms of growth parameters, antibacterial activity and phenolic profile in tomato infected by Clavibacter michiganensis subsp. michiganensis (CmmT7). A significant difference was observed in E. purpura extract, indicating the highest effects on plant height (27.25 cm), fresh plant weight (28.45 cm), root length (24.42 cm), and root weight (6.74 g) (p<0.05). Moreover, Calendula officinalis and Echinacea purpurea extracts showed significant inhibitory activity against CmmT7 (p<0.05). Among phenolic compounds, the only chlorogenic acid amounts were varied in the tomato seedlings leaves with C. officinalis extract (K3) + CmmT7, E. purpurea extract (E3) + CmmT7 and CmmT7 (p<0.01). Moreover, chlorogenic acid amount was approximately 9 times higher than in CmmT7-treated leaves when compared to control. The results showed that application of the extracts of these plants had a significant influence on bacterial canker and growth parameters.

The present study aimed to analyze the chemical composition of the essential oil from Garcinia gardneriana (Planchon & Triana) Zappi leaves and fruits, and to determine its acaricidal activity on Rhipicephalus microplus by larval packet test and larvicidal action on Aedes aegypti by larval immersion test. The chemical analysis of the essential oil by gas chromatography-mass spectrometry identified sesquiterpene hydrocarbons and oxygenated sesquiterpenes in bacupari leaves and fruits, and α-cedrene, α-chamigrene, α-trans-bergamotene, and β-curcumene as major compounds. Essential oil from leaves of G. gardneriana presented acaricidal activity on R. microplus (LC50 = 4.8 mg/mL; LC99 = 10.8 mg/mL) and larvicidal effect on A. aegypti (LC50 = 5.4 mg/mL; LC99 = 11.6 mg/mL), whereas essential oil from the fruits of G. gardneriana showed LC50 = 4.6 mg/mL and LC99 = 8.9 mg/mL against R. microplus and LC50 = 6.4 mg/mL and LC99 = 13.9 mg/mL against A. aegypti. These results thus demonstrate the potential acaricidal and larvicidal activity of essential oil of G. gardneriana, offering new perspectives for the realization of bioassays from this essential oil.

Drimys winteri JR et G. Forster var chilensis (DC) A. is a tree native to central and southern Chile. Also it found in part of Argentina. It is abundant in wet swampy localities from sea level to an altitude of 1700 m. This tree is sacred for the Mapuche culture; it is used in folk medicine in such as inflammatory and painful processes. Phytochemical studies have demonstrated that this plant contains mainly sesquiterpenes of the drimane type, flavonoids, essential oils, phytosterols and some lignans. These drimanes have attracted interest because of their antifeedant, plant growth regulation, cytotoxic, antimicrobial and insecticidal properties. The objective of this review is to establish clearly the phytochemistry and biological activity of Drimys winteri JR et G. Forster var chilensis (DC) A. Articles based on other varieties are not considered.

Resveratrol is a phenolic phytoconstituent found in many plants. This molecule has always caught the attention of scientists because of biological potentials such as inhibition of inflammation, oxidative stress and platelet aggregation as well as to prevent/protect against cardiovascular and neurodegenerative disease/disorders. Literature search have been conducted over resveratrol in covid-19 and asthma studies published in Pubmed and Google Scholars until 30 September 2020. The criteria used in the literature review were determined and were reviewed works on resveratrol including 368 articles and 47 articles on covid-19 and asthma, respectively. As a result of meta-analysis, TNF-α values of the studies showed a significant difference (heterogeneity) of I2=68.39% from each other in total (Cohran Q:6.33, p<0.0423). This study shows that resveratrol would have a potential to reduce ARDS symptoms, by suppressing the cytokine storm and severe inflammation caused by SARS-CoV-2, and by showing strong activity against various types of DNA/RNA viruses.

Semi-structured interviews (80) were applied in order to document the medicinal plants used by the Pijao indigenous community in Natagaima, Colombia. As a result, a total of 110 species distributed in 54 families were registered, Asteraceae and Fabaceae (9% each) being the most important families. Regarding the parts of the plant, the most used structure was leaves (46.7%), the main form of preparation was infusion (32%), and the most used way of administration was oral (77.8%). The value of use of the species by informants (VUis), the relative importance of medicinal species (IRE) and the index of cultural value of medicinal species (IVUs) were determined. The most important species according to their value of use were: Tamarindus indica L., Psidium guajava L., Mentha x piperita L., Moringa oleifera Lam. The most reported ailments were gastrointestinal problems such as stomach pain and diarrhea, general aches, headache, fever, swollen liver, and respiratory problems.

This study determined phytochemical composition, antifungal activity and toxicity in vitro and in vivo of Syzygium cumini leaves extract (Sc). Thus, was characterized by gas chromatography coupled to mass spectrometry and submitted to determination of Minimum Inhibitory (MIC) and Fungicidal concentrations (MFC) on reference and clinical strains of Candida spp. and by growth kinetics assays. Toxicity was verified using in vitro assays of hemolysis, osmotic fragility, oxidant and antioxidant activity in human erythrocytes and by in vivo acute systemic toxicity in Galleria mellonella larvae. Fourteen different compounds were identified in Sc, which showed antifungal activity (MIC between 31.25-125 μg/mL) with fungistatic effect on Candida. At antifungal concentrations, it demonstrated low cytotoxicity, antioxidant activity and neglible in vivo toxicity. Thus, Sc demonstrated a promising antifungal potential, with low toxicity, indicating that this extract can be a safe and effective alternative antifungal agent.
