| Abstract: | This study systematically investigated the retention behavior of seven neutral ginsenosides Rg1, Re, Rf, Rb1, Rb2, Rc, Rd, and an acidic ginsenoside R0, the major pharmacologically active components of Radix Ginseng with RP-HPLC. The effects of solvent, pH value, ionic strength
of the mobile phase, and column temperature were investigated using an octadecylsiloxanebonded silica gel column. Based on
the ginsenosides’ retention characteristics, the concentration of acetonitrile and the gradient of the mobile phase needed
to maintain the baseline separation of the major neutral ginsenosides in Radix Ginseng were theoretically predicted. Furthermore,
the ionic strength of mobile-phase necessary to achieve good resolution of the neutral ginsenosides and acidic ginsenosides
was carefully investigated. According to the results of the quantitative analysis of ginsenosides in eight batches of ginseng
samples from different sources, the developed HPLC technique may be a valuable tool for the quality assessment of Radix Ginseng.
