Abstract
The antioxidant and antibacterial properties of a Phenolic-rich Orthosiphonstamineus leaf extract were investigated in this study. The antibacterial activity was tested using the disc diffusion method and the determination of minimum inhibitory concentration, while the antioxidant activity was determined using reducing power activity, metal chelating activity, and inhibition of lipid peroxidation assay. It also had the highest metal chelating activity and suppression of lipid peroxidation (EC50 of μg mL−1), as well as the highest reducing power (A700 = 0.462) at 100 μg mL−1. Against both Gram-negative and Gram-positive bacteria, it was found to have considerable antibacterial activity when the extracts were tested. These discoveries provided a scientific foundation for Orthosiphon stamineus's traditional use, as well as demonstrating its viability as a rich source of natural antioxidant and antibacterial compounds.
