Abstract:
Objective To study the chemical constituents of the acid hydrolytic products from the stems and leaves of Panax quinquefolium. Methods The stems and leaves of P. quinquefolium were hydrolyzed with acid;Isolation and purification were carried out by various chromatographic techniques,such as silica gel and so on. Compounds were identified and elucidated by spectral and chemical methods. Results Eight compounds were obtained from the acid hydrolytic products in the stems and leaves of P. quinquefolium and identified as 20 (S)-panaxadiol (Ⅰ),20 (S)-protopanaxadiol (Ⅱ),20 (R)-protopanaxadiol (Ⅲ),20 (S)-panaxatriol (Ⅳ),24 (R)-ocotillol (Ⅴ),20 (R)-protopanaxatriol (Ⅵ),20 (R)-dammarane-3?,12?,20,25-tetrol (Ⅶ),and 20 (R)-dammarane-3?,6?,12?,20,25-pentol (Ⅷ). Conclusion Compounds Ⅰ-Ⅷ are the derivates of the aglycones of ginsenosides,isolated from the acid hydrolytic products from the stems and leaves of P. quinquefolium for the first time. Among these compounds,Ⅳ,Ⅶ,and Ⅷ are discoverd from the roots,stems,leaves,fruits,and buds of P. quinquefolium for the first time. Compound Ⅶ is discovered and reported that it is the derivate of the aglycone of protopanoxadiol ginsenoside,with the conspicuous anticancer activity from the fruits of P. ginseng for the first time.
