Figure 1. Quantitative determination of ginsenosides in S4h using High-Performance Liquid Chromatography (HPLC).
(A) HPLC chromatogram of S4h recorded at 202 nm. Four group peaks are enlarged and the retention times indicated under the enlarged window (inset). (B) Analytical data of S4h. The major constituents in S4h were ginsenosides Rg3, Rg2 and 20R-Rg2. Ginsenosides Rg1, Re and Rb2 were not detected. Ginsenoside peak numbers in HPLC chromatogram (A) were shown in (B).
