From Stauntonia hexaphylla, two new 3,28-bisglycosidic triterpenoid glycosides named staunosides A and B, were isolated along with three known triterpenoid glycosides, one of which was isolated from nature of the first time, though it had previously been obtained from the acid hydrolysate of kizuta saponin K12. On the basis of chemical and physicochemical evidence, the structures of staunosides A and B were elucidated as 3-O-(beta-D-glucopyranosyl)-hederagenin-28-O-[beta-D- glucopyranosyl(1-->6)-beta-D-glucopyranosyl]ester and 28-O-[alpha-L-rhamnopyranosyl(1-->4)-beta-D-glucopyranosyl(1-->6)- beta-D-glucopyranosyl]ester, respectively.
从六叶野木瓜中分离得到了两种新的3,28 - 双糖苷三萜类糖苷，分别命名为野木瓜苷A和野木瓜苷B，同时还得到了三种已知的三萜类糖苷，其中一种是首次从自然界中分离得到，尽管它之前是从木通皂苷K12的酸水解产物中获得的。基于化学和物理化学证据，野木瓜苷A和野木瓜苷B的结构分别被阐明为3 - O -（β - D - 吡喃葡萄糖基）- 常春藤皂苷元 - 28 - O - [β - D - 吡喃葡萄糖基（1→6）-β - D - 吡喃葡萄糖基]酯和28 - O - [α - L - 鼠李吡喃糖基（1→4）-β - D - 吡喃葡萄糖基（1→6）-β - D - 吡喃葡萄糖基]酯。
