摘　　要：A new triterpenoid saponin, namely pomatoside A (3) 13beta, 28-epoxy-16-oleananone-3-O-[alpha-L-rhamnopyranosyl-(1 -->6)-O-beta-D-glucopyranosyl-(1 -->4)-O-beta-D-glucopyranosyl-(1 -->6)-O-beta-D-glucopyranosyl-(1 -->2)]-beta-D-glucopyranoside, together with twelve known compounds, was isolated for the first time from Pomatosace filicula Maxim., a monotypic endemic plant, grown in the Qinghai-Xizang Plateau of China. Their structures were elucidated by spectroscopic analyses and chemical methods, especially 2D-NMR.首次从中国特有的单属单种植物羽叶点地梅(Pomatosace filicula Maxim.)分离到13个化合物。应用波谱技术(尤其足2D-NMR:TOCSY, HMQC,HMBC)及化学方法鉴定了它们的结构。其中,化合物3为一新的三萜皂苷类化合物,其结构为13β,28-epoxy-16-oleananone-3-O-[α-L-rhamnopyranosyl-(1→6)-O-β-D-glucopyranosyl(1→4)-O-p-glucopyranosyl-(1→6)-O-β-D-glucopyranosyl-(1→2)]-β-D-glucopyranoside,命名为羽叶点地梅甲苷(pomatoside A)。
