The dried and ground sample subjected for extraction by shaking method with different solvents i. e. 75% methanol and ethanol. In the present study antioxidant activity of plant Swertia chirata was investigated by measuring total phenolics (TPC), total flavonoids (TFC), DPPH (2, 2-Diphenyl-1-picrylhydrazyl) and Percent inhibition of linoleic acid peroxidation. The total phenolics (TPC) obtained from methanol 2. 565g / 100g from ethanol 1. 612g / 100g gallic acid equivalents. TFC obtained from methanol 13. 247g / 100g from ethanol 10. 948g / 100g catechin equivalents, inhibition of linoleic acid peroxidation obtained from methanol 94. 04% from ethanol 93. 05% and Percentages scavenging of plant Swertia chirata...
