Antioxidant activity of Schisandra chinensis extract and derivatives

摘要

Antioxidant activities of acetone and methyl ethyl ketone extracts from leaves of Schisandra chinensis, one of traditional Chinese medicine consumed in the eastnorth region of China, were examined by a DPPH (1,1-Diphenyl-2-picrylhydrazyl) radical-scavenging assay and a β-carotene-linoleic acid test. In DPPH, the antioxidant activity of the acetone extracts, methyl ethyl ketone extracts and derivative were superior to that of control with IC_(50) were 256.54, 342.28 and 124.32μg/mL, respectively. In the β-carotene-linoleic acid test, IC_(50) were 278.29, 384.12 and 145.25μg/mL. It was concluded that Schisandra chinensis and its derivatives might be a potential natural source of antioxidants.
