Abstract
The present study was carried out to evaluate the in vitro antioxidant activities of methanolic extract of Prunella vulgaris , a valuable medicinal plant from Central Himalayans

This was achieved by screening of the plant extracts at varying concentrations (1-70 µ g/ml), using 2,2-diphenyl-1-picryl- hydrazyl (DPPH ) radical scavenging activity, reducing power assay superoxide radical scavenging activity, metal chelating activity, and analysis o f total antioxidant activity by ABTS method.
