Studies on dammarane-type saponins in the flower-buds of Panax ginseng C.A. Meyer.
From the dried flower-buds of Panax ginseng C.A. Meyer, a new minor dammarane-type triterpene saponin named ginsenoside III together with nine known saponins was isolated. On the basis of spectral and chemical evidence, the structure of the new saponin was elucidated as 3-O-[beta-D-glucopyranosyl(1-->2)-beta-D-glucopyranosyl]-20-O-beta- D-glucopyranosyl-3 beta,12 beta,20(S)-trihydroxy-dammar-25...

متن کاملIsolation, Purification and Quantification of Ginsenoside F₅ and F₃ Isomeric Compounds from Crude Extracts of Flower Buds of Panax ginseng.
In this paper, the isolation, purification and quantification of ginsenoside F₅ and F₃ isomeric compounds from crude extracts of flower buds of Panax ginseng (CEFBPG) was investigated by reversed-phase high-performance liquid chromatography (RP-HPLC) for the first time. The satisfied separation at analytical scale was achieved using a Zorbax Eclipse XDB C-18 column with a ternary mobile phase o...
متن کاملComplete 1H-NMR and 13C-NMR spectral assignment of five malonyl ginsenosides from the fresh flower buds of Panax ginseng
BACKGROUND Ginsenosides are the major effective ingredients responsible for the pharmacological effects of ginseng. Malonyl ginsenosides are natural ginsenosides that contain a malonyl group attached to a glucose unit of the corresponding neutral ginsenosides. METHODS Medium-pressure liquid chromatography and semipreparative high-performance liquid chromatography were used to isolate purified...
