The evaluation of contents of nine ginsenoside monomers in four commercial ginseng by reverse phase high performance liquid chromatography (RP-HPLC)

摘要

Nine ginsenoside monomers (Rg1, Rg2, Rf, Re, Rb1, Rb2, Rb3, Rc) were simultaneously determined by reverse phase high performance liquid chromatography (RP-HPLC) to assay chemical components in white ginseng, red ginseng, sugar ginseng and fresh ginseng. The results demonstrated that four different processing ginseng contained the same type of ginsenosides (Rg1, Rg2, Rf, Re, Rb1, Rb2, Rb3, Rc), but the content of each ginsenoside monomer varied significantly (P&0.05). The quality of those four different types of ginseng was evaluated according to the total content of nine ginsenoside monomers, and the results showed that white ginseng was the best, followed by sugar and fresh ginseng was the worst.
