Antioxidant activities of extracts and their main constituents of Callicarpa nudiflora
摘要
Abstract
Callicarpa nudiflora is a famous region drug of Hainan Province, which is mainly used as anti-inflammatory and hemostatic agents. The plant is rich in flavonoids and phenylethanoid glycosides, which have been proved to be one of the main source of natural antioxidants. To investigate the antioxidant capacities of C. nudiflora, the authors use DP-PH scavenging method to determine the antioxidant activity of different polar extracts of C. nudiflora and its main constit-uents. The alcohol extract, water fraction, butyl alcohol fraction, ethyl acetate fraction showed strong antioxidant activity. Three main compounds, luteolin, luteolin-7-O-β-D-glucoside and acteoside, possessed significant antioxidant activity while 5-hydroxy-3,7,3′,4′-tetramethoxyflavone exhibited weak antioxidant activity. The research will provide the evidence for development of health products of C. nudiflora.关键词
