Three ginsenosides were isolated from flower-buds of Panax ginseng C.A. Meyer of Jilin by column chromatography on silica gel repeatedly .Their structures were identified as ginsenoside-Rg2 (Ⅰ),-Re(Ⅱ)and-Rd(Ⅲ) Respectively, by means of IR spectra,nuclear magnetic resonance and mass spectra of their acetylated compounds, as well as from their chemical properties, and by direct comparison with the authentic samples these were confirmed.
