Abstract
Using reversed-phase high performance liquid chromatography, nine ginsenosides were simultaneously separated on an UltimateC₁₈ column with high-resolution and high purity of each chromatographic peak. Adopting the QAMS quality evaluation model for traditional Chinese medicines, ginsenoside Rb₁ was used as the internal reference substance, and the relative correction factors (RCFs) and the relative retention values (RTRs) of ginsenosides Rg₁, Re, Rf, Rb₁, Rc, Rb₂, Rb₃, Rd and 20 (S)-ginsenoside Rg₃ to ginsenoside Rb₁ were calculated individually. Through a series of methodology evaluations, and positioned by the red ginseng reference chromatograph and RTVs, nine ginsenosides in red ginseng were simultaneously assayed only by quantitative determined ginsenoside Rb₁.
