In-vitro antioxidant potential of solvent extracts from Anisomeles malabarica

Abstract

Anisomeles malabarica (Linn.) Lamiaceae found in Western Ghats of southern India. This plant has traditional medicinal value with phytochemical components which have antioxidant potential. In this present study investigation was done to evaluate in vitro antioxidant assay by DPPH (1, 1-diphenyl-2-picryl hydrazyl) free radical scavenging activity and reducing ability with leaf extracts of A. malabarcia using various solvents (methanol and hexane). It was found that methanol and hexane leaf extracts showed good potency of antioxidant activity. Comparative study of these crude extracts revealed that methanol extract was more effective than hexane. Methanol extract showed very good antiradical activity and reductive ability against standard antioxidant (BHA) and standard reductive agent ascorbic acid. Even hexane extract also revealed some good potential comparison with these standards. The result suggests that the methanol extract of A. malabarica contains relatively significant quantities of novel active antioxidant compounds compared with hexane extract.
