The study examined the antioxidant activity of methanol extracts of three widely used medicinal herbs belonging to the family Apocynaceae namely Tabernaemontana corymbosa, Plumeria rubra and Thevetia peruviana and their combinations was investigated and compared. Methanol extract was prepared by subjecting plant leaves of three species. Qualitative phytochemical screening was performed to check the presence to major phytochemical constituents of each plant. Our study reveals that T. corymbosa possesses more antioxidant activity than other studied plants. Our results also suggest that reduction potential of different concentration of aqueous solution are higher in T. peruviana that that of other two species. It also suggests that T. peruviana had higher reduction potential that can cause antagonism antioxidant activity. Therefore, the study considered that medicinal plants acquire substantial amount of antioxidant and may contribute to the well-being of individuals who consume them.
