从民间抗生育药山苷草Mussaenda pubesecus的总皂苷酸水解产物中, 分离得到MP-C、D、E和F四个化合物, 经UV、IR、NMR、MS解析和化学方法, 确定了它们的化学结构。MP-C为一种新型的含有酰胺键接γ-内酯环的三萜化合物, 一新近报道的Heinsiagenin A的结构一致。MP-D、E和F分别为MP-C的β-D吡喃葡萄糖苷、β-D-吡喃木糖苷和β-D吡喃葡萄糖(1→2)-β-D-吡喃木糖苷, 均为新化合物, 分别命名为MussaendosideA、B和C。

A cyclolanostene-type triterpene and 3 of its saponins, were isolated from the acid-hydrolyzate of the mixture of saponins of Mussaenda pubesecus. Their structures were elucidated on the basis of chem. and UV, IR, 1H, 13C NMR, and mass spectral evidence. The triterpene was identified as heinsiagenin A (I, R = H), a recently, reported new cyclolanostene-type triterpene with a g-lactone attached at its 27-amide group. The saponins were identified as I [R = b-D-glucopyranosyl, b-D-xylopyranosyl, b-D-glucopyranosyl-(1?)-b-D-xylopyranosyl], named mussaendoside A, B, and C, resp.
