从五加科植物Nothopanax davidii (Franch) Harms 中分离得到两个新的齐墩果烷型三萜苷，命名为一叶两万糖苷I 和一叶两万糖苷II。通过化学和光谱分析阐明了它们的化学结构。一叶凉丸苷I：C57H88O25，白色粉末，mp 203-205℃(分解)，αD20-3.47(c 0.1，CH 3 OH)。其结构确定为3-O-α-(3',4'-O-二酸-乙酰基)-L-阿拉伯吡喃糖基-3β-羟基油酸-12-烯-28,29-二酸-28-O-[α-L-吡喃鼠李糖基-(1----6)-β-D-吡喃葡萄糖基- (1----4)-β-D-吡喃葡萄糖基]酯。一叶凉丸苷II：C37H56O10，白色粉末，熔点240-244℃(分解)，αD20+36.5(c 0.1，CH3OH)。其结构被确定为3-O-α-(3'-O-乙酰基)-L-阿拉伯吡喃糖基-3β-羟基齐墩果酸-12-烯-28,29-二酸。
Two new oleanane type triterpene glycosides, named yiyeliangwanoside I and yiyeliangwanoside II, were isolated from Nothopanax davidii (Franch) Harms (Araliaceae). Their chemical structures were elucidated by means of chemical and spectrometric analysis. Yiyeliangwanoside I: C57H88O25, a white powder, mp 203-205 degrees C (dec.), [alpha]D20-3.47(c 0.1, CH3OH). Its structure was determined as 3-O-alpha-(3',4'-O-dioic-acetyl)-L-arabinopyranosyl-3 beta-hydroxyolean-12-ene-28,29-dioic acid-28-O-[alpha-L-rhamnopyranosyl-(1----6)-beta-D-glycopyranosyl- (1----4)-beta-D-glycopyranosyl] ester. Yiyeliangwanoside II: C37H56O10, a white powder, mp 240-244 degrees C (dec.), [alpha]D20+36.5(c 0.1, CH3OH). Its structure was determined as 3-O-alpha-(3'-O-acetyl)-L-arabinopyranosyl-3 beta-hydroxyolean-12-ene-28,29-dioic acid.
