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...
