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(
Two minor compounds isolated from the leaves of Panax ginseng C. A. Meyer were characterized as 20(R)-protopanaxadiol (I) and 3 beta, 6 alpha, 12 beta-trihydroxydammar-20 (22), 24-diene-6-O-alpha-L-rhamnosyl-(1----2)-beta-D-glucopyranoside (II) on the basis of spectral analysis and chemical
20(S)-protopanaxadiol (PPD(S)) and 20(R)-protopanaxadiol (PPD(R)), the main metabolites of ginsenosides Rg3(S) and Rg3(R) in black ginseng, are potential candidates for anti-cancer therapy due to their pharmacological activities such as anti-tumor properties. In the present study, we report the
