| 論文備考 | To analyze racemic 20 (R, S)-ginsenoside-Rg2, an anti-shock agent, a simple and reproducible high-performance liquid chromatographic (HPLC) method has been developed. The enantiomeric separation and determination were successfully achieved using a DiamonsilTM ODS C18 reversed-phase column with an RP18 guard column and a mobile phase of MeOH-aq. 4% H3PO4 (65:35, v/v, pH 5.1) with UV detection at 203 nm. Both enantiomers, 20 (R)-ginsenoside-Rg2 and 20 (S)-ginsenoside-Rg2, were well separated at 14.5 min and 13.6 min, respectively. In pharmacokinetic studies in rat plasma after intravenous administration of 20 (R, S)-ginsenoside-Rg2, the enantiomers were rapidly absorbed and eliminated.
