Two New Tirucallane-Type Triterpenoid Saponins from Sapindus mukorossi

TENG Rong-Wei, NI Wei, HUA Yan and CHEN Chang-Xiang   


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-α-L-rhamnopyranosyl-(1→2)-[α-L-arabinopyranosyl-(1→3)]-β-D-glucopyranosyl-21, 23R-epoxyl tirucall-7, 24R-diene-3β, 21-diol(1) and 3-O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranosyl-21, 23R-epoxyl tirucall-7,24R-diene-3β, 21-diol(2). Key words: Sapindus mukorossi; Sapindaceae; triterpenoid saponin; Sapimukoside A; Sapimukoside B

从无患子科无患子(Sapindus mukorossi Gaertn.)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-21,23R-epoxyl tirucall-7,24R-diene-3β,21-diol(1)和3-O-α-L-鼠李吡喃糖基-(1→6)-β-D-葡萄吡喃糖基21,23R-epoxyl tirucall-7,24R-diene-3β,21-diol(2)。
