Determination of Saponins in Leaf of Panax Ginseng C. A. Mey. by High Performance Liquid Chromatography

摘要： A high performance liquid chromatography(HPLC) with UV detection was established for simultaneous determination of saponins in the leaf of Panax ginseng C. A. Mey. Nine ginsenosides(Rb1,Rb2,Rb3,Rc,Rd,F1,F2,F3,F5) and notoginsenoside Fe(NFe) were studied. Among the saponins,the ginsenosides F1,F2,F3,F5 and NFe were determined by HPLC-UV method for the first time. The determination of the ginsenosides via the HPLC-UV method was performed on a reversed-phase C18 column with gradient elution in 40 min. The linearity,precision,accuracy,and detection limit for determining the saponins were studied and the samples from different areas in China were analyzed. The HPLC-ESI-MS was used to identify the saponins. The results indicate that the HPLC-UV pro-vided a good accuracy,reproducibility and sensitivity for the determination of the ten saponins. ... （共5頁）
