In vitro antioxidant activity of Clitoria ternatea Linn.

Abstract

The objective of the study was to evaluate the in vitro antioxidant activities of Clitoria ternatea. Various concen- trations(250, 500, 750 and 1000µg) of the methanol extract of Clitoria ternatea (MECT) was subjected to reducing power assay, superoxide anion scavenging assay, hydroxyl radical scavenging assay, lipid peroxidation assay and DPPH(2,2 diphenyl-1-picryl hydrazyl) assay, with ascorbic acid as standard. The extract exhibited significant reduc- ing power and free radical scavenging effects. The findings suggest that the methanol extract of Clitoria ternatea is a source of natural antioxidants and could be used in the treatment and management of free radical mediated diseases.
