Abstract

The present study aimed to evaluate the in-vitro antioxidant activities of Cissus quadrangularis L. stem. The preliminary phytochemical assay using solvents of different polarity namely water, 50% hydroethanol, ethanol, acetone, chloroform and petroleum ether showed the presence of secondary metabolites like flavanoids, alkaloids, tannins, triterpenoids, carbohydrates, saponins, glycosides, ligins and inulins. Among all the extracts, hydroethanol extract showed the presence of more secondary metabolites. Hence it was utilized for antioxidant assays like superoxide radical scavenging activity, hydroxyl radical scavenging activity and metal chelating activity. These results revealed that the 50% hydroethanol extract of Cissus quadrangularis L. stem possessed potent antioxidant properties.

Keywords: Cissus quadrangularis L., phytochemistry, antioxidant activity.
