Abstract:
OBJECTIVETo establish methods for quantitative determination of ginseng saponins, ginsenoside Rg1, Re, Rb1 and polysaccarides and compare the qualities of Tongrentang Red Ginseng and Korean Red Ginseng.
METHODMacroreticular resin-colorimetric method was developed to determine ginseng saponins and a new HPLC method with gradient eluents was established for determination of ginsenoside Rg1, Re, Rb1. For ginseng polysaccharides, phenol-oil of vitriol colorimetric method was developed and some factors were also optimized.
RESULTThe content of ginseng saponins in Tongrentang Red Ginseng was not lower than that of Korean Red Ginseng. Ginsenoside Rg1 and Rb1 in Tongrentang Red Ginseng were higher than those in Korean Red Ginseng, while Ginsenoside Re was slightly lower than that of Korean Red Ginseng. However, the amount of Ginseng Polysaccharides in Tongrentang Red Ginseng was greater than those in Korean Red Ginseng.
CONCLUSIONThe contents of ginseng saponins and ginsenoside Rg1, Re, Rb1 in Tongrentang Red Ginseng were not lower than that in Korean Red Ginseng. The methods for determination of ginsenosides and ginseng polysaccharides were quite accurate and reliable to the quality control of Ginseng.
