Background

As a typical Chinese herbal medicine, rhizoma Cimicifugae (RC, in Chinese) possesses various pharmacological effects involved in antioxidant activity.

Methods

Firstly, five RC extracts (i.e. petroleum ether extract PERC, ethyl acetate extract EARC, absolute ethanol extract AERC, 95% ethanol extract 95ERC, and water extract WRC) were prepared and determined by various antioxidant methods, including anti-lipidperoxidation, protection against DNA damage, ·OH scavenging, ·O2- scavenging, DPPH· (1,1-diphenyl-2-picryl-hydrazl radical) scavenging, ABTS+· (2,2'-a
