Seventeen compounds were isolated from the leaves of PANAX GINSENG C. A. Meyer. Among them, a new minor saponin was established as 3beta,6alpha,12beta-trihydroxy-dammar-20(22), 24-diene-6- O-alpha- L-rhamno-pyranosyl-(1-->2)-beta- D-glucopyranoside ( 2). Fourteen compounds were identified as 20(
Five compounds were isolated from the leaves of Panax ginseng and characterized as 20(R)-protopanaxatriol, daucosterine, ginsenoside-F2, ginsenoside-F3 and majoroside-F4 on the basis of spectral analysis and chemical evidence. Among them, majoroside-F4 is obtained from plant for the first time.
Four compounds were isolated from the fruit of cultivated Panax ginseng and identified as beta-sitosterol,20(R)-protopanaxatriol, daucosterine and 20(R)-ginsenoside-Rg3 on the basis of physicochemical constants and spectral evidences.
An effective method for simultaneous determination of five hydrolysis products of 20 (R)-dammarane-3β,6α,12β,20,25-pentol, 24(R)-ocotillol, 20(R)-protopanaxatriol, 20(S)-panaxatriol and 20(R)-dammarane-3β,12β,20,25-tetrol was developed using high-performance liquid chromatography with evaporative
