A new angeloylated oleanane-type triterpenoid saponin, sorbifoliaside (1), and a known saponin, xanifolia O54, were isolated from the husks of Xanthoceras sorbifolia Bunge. Their chemical structures were elucidated on the basis of various spectroscopic analyses coupled with chemical degradation. To our knowledge, compound 1 is the first example of a naturally occurring triterpenoid saponin with an angeloyl group at C-2 of the sugar moiety.
从文冠果（Xanthoceras sorbifolia Bunge）的外壳中分离得到了一种新的酰化齐墩果烷型三萜皂苷，即山桐子苷（1），以及一种已知的皂苷，即 Xanifolia O54。基于各种光谱分析和化学降解，确定了它们的化学结构。据我们所知，化合物 1 是第一个在糖部分的 C-2 位上具有酰基的天然存在的三萜皂苷。
