Abstract
India has vital deposit of various herbs and is used in many parts ofthe country as traditional medicinal treatment like Ayurveda, Unani, Siddha and Homeopathy. With increasing problems of side effects related to chemical drug usages and increasing activity of over drug usages has led to multidrug resistant organisms. In
this research we focused on using the plant sources like Piper betle leaves and Cissus quadrangularis stems for understanding their antioxidant scavenging activity. We have extracted the vital compounds using cold percolation method and the methanolic extract was chosen for various antioxidant activity like DPPH, ABTS+, FRAP, Hydrogen peroxide and hydroxyl radical scavenging activity. We have found that both the plant extracts showed higher activity and IC50 value for both the extracts in all the tests showed nearly 60 μg mL-1 and the graph was plotted using the percentage of inhibition scavenging activity vs the concentration taken for each plant extracts
