The present study was undertaken to explore the phytochemical screening, anti-bacterial and anti-oxidant activities of the hydro-methanolic leaves extract of Mangifera indica using standard screening methods such as disc diffusion and DPPH methods. In phytochemical screening, Mangifera indicaextract showed presence of secondary metabolites such as carbohydrate, phenols, tanins and proteins whereas Saponins were absent. It also showed antibacterial activities against almost all the test organisms. The extracts possessed potent hydroxyl radical scavenging activity against the positive control standard Ascorbic acid. Results denote the presence of hydroxyl radical scavenging principles in the extracts.

In order to contribute to the fight against infectious diseases, thein vitroantibacterial activity and the antibiotic-potentiating effects ofTristemma hirtumand five other Cameroonian edible plants have been evaluated against Gram-negative multidrug-resistant (MDR) phenotypes. The microdilution method was used to evaluate the bacterial susceptibility of the extracts and their combination to common antibiotics. The phytochemical screening of the extracts was carried out according to standard methods. Phytochemical analysis of the extracts revealed the presence of alkaloids, triterpenes, steroids, and polyphenols, including flavonoids in most of the tested extracts. The entire tested extracts showed moderate (512 μg/mL ≤ MIC ≤ 2048 μg/mL) to weak (MIC > 2048 μg/mL) antibacterial activities against the tested bacteria. Furthermore, extracts of leaf ofTristemma hirtumand pericarpsofRaphia hookeri(at their MIC/2 and MIC/4) strongly potentiated the activities of all antibiotics used in the study, especially those of chloramphenicol (CHL), ciprofloxacin (CIP), kanamycin (KAN), and tetracycline (TET) against 70% (7/10) to 100% (10/10) of the tested MDR bacteria, with the modulating factors ranging from 2 to 128. The results of this study suggest that extracts from leaves ofTristemma hirtumand pericarps ofRaphia hookerican be sources of plant-derived products with antibiotic modifying activity.

Selaginella Tamariscina

In Vietnam, Selaginella tamariscina (Beauv.) Spring. has been used as a traditional medicine for osteoarthritis, haemorrhage, hepatitis, burn, … However, Selaginella tamariscina is less studied than in other countries. Therefore, this research focuses on study some bioactivities (such as antioxidative, antibacterial activities, and inhibition of albumin denaturation) and preliminary phytochemical screening of six extracts (ethanol extracts of root, leaf, whole plant, petroleum extracts of root, leaf, whole plant) of S. tamariscina collect from Co Thach, Binh Thuan Province. The preliminary phytochemical screening results show that Selaginella tamariscina extracts have most of secondary metabolite groups such as phenolics, alkaloids, flavonoids, steroids, and lactone. The antibacterial activity of the ethanol extract of root is higher than that of other extracts. Moreover, the ethanol extract of root also has the highest reducing ability and free radical scavenging activity, with EC50 = 1.590 ± 0.091mg/ml. In the anti-denaturation of albumin test, the petroleum ether extract of whole plant has the lowest IC50 at 99 ± 5μg/ml.
