Abstract

Using a reversed-phase high performance liquid chromatography, the separation of 20(S)-, 20(R)-prosapogenin stereo-isomers of ginsenoside-<TEX>$Rg_2$</TEX> and of ginsenoside-<TEX>$Rg_3$</TEX> in ginseng saponins has been carried out with binary solvent system. The optimum conditions for the isomer separation are as following: Nova-<TEX>$Pak^{(R)}C_{18}$</TEX> (Waters, <TEX>$3.9{\times}150mm$</TEX>) column, <TEX>$CH_3CN/CH_3CN$</TEX> (100:8, v/v) binary solvent system and the flow rate was 1.7 mL/min. The stereoisomers were separated with change of the mixture ratio of the solvent system, the solvent elution by gradient program, and then detected at 203 nm of UV detector. The simultaneous separation of mixture that were the <TEX>$Rg_2$</TEX>, <TEX>$Rg_3$</TEX> isomers was easily performed in nonpolar solvent for <TEX>$Rg_2$</TEX>, polar solvent for <TEX>$Rg_3$</TEX> at the same optimum conditions.
