EVALUATION OF ANTIOXIDANT POTENTIAL OF CLITORIA TERNATEA L.

摘要

Clitoria ternatea L. (C. ternatea var. ternatea and C. ternatea var. pilosa) are herbaceous medicinal plant are used in India to treat liver problems. The objective of this study is to investigate the antioxidant activities to justify the use of the plant in folkloric medicine. A ntioxidant activities of different fractions from different extracts (Leaves, Stem and Root) were evaluated by using antioxidant assay like DPPH, FRAP, Metal Chelating Ability, Reducing Power assay. Methanolic extract of C. ternatea var. pilosa root showed highest value 87.75±0.05% and 74.26±0.04% in DPPH and Ferrous ion chelating activity whereas its stem extract 0.588±0.2 and leaves extract 2.132±0.037 mg of AAE per 100 g in FRAP and Reducing power assay respectively. Almost all the fractions of white variety showed highest activity as compare to blue variety. The results obtained in this st udy showed that both variety of C. ternatea have antioxidant properties which provide a basis for the traditional use of plant and could be harnessed as drug formulation.
