Ethanol and water extracts of white and fermented ginseng were prepared and their ginsenoside composition and antioxidant effects were assessed. The main ginsenosides in white ginseng were Rb-1>Re>Rg(1), and those in fermented ginseng were Rb-2+Rb-3>Rd>Rg(1). Ginsenosides Rd and Rg(3) in fermented ginseng were enriched 11 and 58 times, respectively, over that in white ginseng through fermentation with five Bacillus spp. The greatest levels of 2-deoxyribose and superoxide anion dismutase-like activities were found in 50% ethanol extracts of fermented ginseng. Thus, these data suggest that white ginseng has the greatest free radical scavenging activity and that fermented ginseng has the highest antioxidant activity.
