The minor ginsenosides with less polarity from Panax notoginseng leaves may have more potent biological activities. Four minor saponins, i.e. gypenoside XVII, ginsenoside Rd2, notoginsenoside Fe and notoginsenoside Fd, were successfully separated from Panax notoginseng leaves after biotransformation by one-step counter-current chromatography using the biphasic solvent system consisting of n-butanol-ethyl acetate-water (1:4:5, v/v/v). 30 mg of the refined extract of Panax notoginseng leaves produ...
