摘要
本文采用不同于文献的技术方法,对中国产鲜人参中的天然皂甙——丙二酸单酰基人参皂甙进行了分离、鉴定研究,从中国产鲜人参中分离出四种单体化合物。其中三种经理化及光谱鉴定为:丙二酸单酰基人参皂甙Rb_1,Rb_2,Rd(Malonyl—ginsenosides Rb_1,Rb_2,Rd)。三者系首次从中国鲜人参中获得。
To study the pharmacologic effect of the original ginsenosides and the mechanism of their transformation and degradation in the course of ginseng processing, we isolated four chemical constituents from the fresh ginseng root cultivated in China by means of different methods. On the basis of the physicochemical properties and spectroscpic analysis, three of them were ducidated as Malonyl-ginsenosid Rb1, Rb2, and Rd. They were first isolated from the fresh ginseng root cultivated in China. Their were established to be 3 -O- {6-O-malonyl-β-D-glucopyra-nosyl(l-2)-β -D-glucopyranosyl} - 20-O- {β-D-glucopyranosyl (1- 6) - β-D-glucopyranosyl} -20(S)-protopanaxadiol; 3 -O- (6 - O-malonyl -p-D-glucopyranosyl(1 -2)- β-D-glucopyranosyl} - 20-O- {a-L-arabinopyranosyl (l-6) -3-D-glucopyranosyl}-20 (S)-protopanaxadiol; 3-O- {6 -O-malonyl-3-D-glucopyranosyl (1-2) - β-D-glucopyranosyl} - 20- {β-D-glucopyranosyl} - 20(S)-protopanaxadiol.
