Abstract:

The methanolic extract of young and mature leaves of nine coastal plants from West coast of Maharshtra were analysed to evaluate free radical scavenging activity. The antioxidant activity was evaluated using 1,1-diphenyl-2-picryl hydrazyl radical (DPPH) and the reductive potential of the methanolic extract. The highest antioxidant activity was recorded in young leaves of Hibiscus tiliaceus (76 %), followed by Syzigium corymbosa (71 %) Calophyllum inophyllum (68 %) and Colubrina asiatica (55 %). The plant species also posseses appreciable reductive potential. The leaves of these species were found to be rich in Flavanoids (6.03 to 16.63 mg /g of dry weight) and total polyphenol (12.12 to 26.23 mg /g of dry weight) and these compounds mainly contributed the antioxidant potential of these plants.
