Plants have been an important source of medicine for thousands of
years. Plants are rich source of natural antioxidant i.e.
tocopherols, vitamin C, flavonoids and phenolic compounds. Whole
plant samples of Swertia chirata were purchased from the local
market of Faisalabad, Pakistan. 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 obtained from methanol extract
84.32% from ethanol extract 82.54%.
