Objectives: Plants represent a diverse template that could be tapped as sources of novel drugs. This study highlights antioxidant, anti-inflammatory, anti-proliferative and as well antimicrobial activities of Combretum glutinosum (BE) and Gardenia aqualla (GE) roots ethanol extracts. Methods: The Biological activities were evaluated using the established standard methods. Results: Both extracts exhibited antioxidant and anti-inflammatory activities with BE being better than GE. Anti-proliferative (cytotoxicity) assay on HepG2 and BHK-21 cell lines similarly revealed that BE (IC 50 : 55, SI: 1.81) is more cytotoxic and more selective than GE (IC 50 : 478.60, SI: 0.99). For the antimicrobial study, BE inhibited the growth of pathogenic bacteria; Pseudomonas aeruginosa, Staphylococcus aureus, Vibrio species and E. coli, while GE extract showed activity against Candida albicans. Conclusion: We conclude that Combretum glutinosum extract (BE) possessed the most robust activity from this study. Hence, it could be a promising source of novel drug with wide biological activities, especially antioxidant and anticancer activities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
