摘　　要：Two new tirucallane-type triterpenoid saponins, Sapimukoside A (1) and Sapimukoside B (2), were isolated from the roots of Sapindus mukorossi Gaertn. On the basis of spectroscopic and chemical evidence, their structures were elucidated to be 3-O-alpha-L-rhamnopyranosyl-(1-->2)-[alpha-L-arabinopyranosyl-(1-->3)]-beta-D-glucopyranosyl-21, 23R-epoxyl tirucall-7, 24R-diene-3beta, 21-diol (1) and 3-O-alpha-L-rhamnopyranosyl-(1-->6)-beta-D-glucopyranosyl-21, 23R-epoxyl tirucall-7, 24R-diene-3beta, 21-diol (2).从无患子科无患子 (SapindusmukorossiGaertn .)根中分离到两个新的大戟烷型三萜皂甙SapimukosideA (1)和SapimukosideB (2 )。运用波谱和化学方法鉴定它们的结构为 3_O_α_L_鼠李吡喃糖基_(1→ 2 )_[α_L_阿拉伯吡喃糖基_(1→ 3) ]_β_D_葡萄吡喃糖基_2 1,2 3R_epoxyltirucall_7,2 4R_diene_3β ,2 1_diol (1)和 3_O_α_L_鼠李吡喃糖基_(1→ 6 )_β_D_葡萄吡喃糖基 2 1,2 3R_epoxyltirucall_7,2 4R_diene_3β ,2 1_diol(2 ) .
