Three novel triterpenoid saponins, named masonosides A-C, were isolated from the corms of Crocosmia masoniorum. On the basis of spectral and chemical evidence, the structures of masonosides A-C were elucidated as 3-O-[alpha-L-arabinopyranosyl-(1-->6)-beta-D-glucopyranosyl]-28-O- (2-O- [beta-D-apiofuranosyl-(1-->4)-beta-D-xylopyranosyl-(1-->4)- alpha-L-rhamnopyranosyl]-3-O-(beta-D-glucopyranosyl)-4-O-(2-hydroxy-9-ox o-16- alpha-L-rhamnopyranosyloxyhexadecanoyl)- beta-D-fucopyranosyl)-polygalacic acid, 3-O-[alpha-L-arabinopyranosyl-(1-->6)- beta-D-glucopyranosyl]-28-O-(2-O-[beta-D-apiofuranosyl-(1-->4)-bet a-D- xylopranosyl-(1-->4)-alpha-L-rhamnopyranosyl]- 3-O-(beta-D-glucopyranosyl)-4-O-(2,16-dihydroxy- 9-oxohexadecanoyl)-beta-D-fucopyranosyl)-polygalacic acid and 3-O-[alpha-L-arabinopyranosyl-(1-->6)-beta-D-glucopyranosyl]- 28-O-(2-O-[beta-D-xylopyranosyl-(1-->4)-alpha-L-rhamnopyranosyl]-3-O- (beta-D-glucopyranosyl)-4-O-(2,16-dihydroxy- 9-oxohexadecanoyl)-beta-D-fucopyranosyl)-polygalacic acid, respectively.
从雄黄兰的球茎中分离出三种新的三萜皂苷，命名为雄黄兰皂苷A - C。基于光谱和化学证据，雄黄兰皂苷A - C的结构分别被阐明为3 - O - [α - L - 阿拉伯吡喃糖基 - (1→6) - β - D - 葡萄糖吡喃糖基] - 28 - O - (2 - O - [β - D - 芹菜呋喃糖基 - (1→4) - β - D - 木糖吡喃糖基 - (1→4) - α - L - 鼠李吡喃糖基] - 3 - O - (β - D - 葡萄糖吡喃糖基) - 4 - O - (2 - 羟基 - 9 - 氧代 - 16 - α - L - 鼠李吡喃糖氧基十六烷酰基) - β - D - 岩藻吡喃糖基) - 多星果酸、3 - O - [α - L - 阿拉伯吡喃糖基 - (1→6) - β - D - 葡萄糖吡喃糖基] - 28 - O - (2 - O - [β - D - 芹菜呋喃糖基 - (1→4) - β - D - 木糖吡喃糖基 - (1→4) - α - L - 鼠李吡喃糖基] - 3 - O - (β - D - 葡萄糖吡喃糖基) - 4 - O - (2,16 - 二羟基 - 9 - 氧代十六烷酰基) - β - D - 岩藻吡喃糖基) - 多星果酸和3 - O - [α - L - 阿拉伯吡喃糖基 - (1→6) - β - D - 葡萄糖吡喃糖基] - 28 - O - (2 - O - [β - D - 木糖吡喃糖基 - (1→4) - α - L - 鼠李吡喃糖基] - 3 - O - (β - D - 葡萄糖吡喃糖基) - 4 - O - (2,16 - 二羟基 - 9 - 氧代十六烷酰基) - β - D - 岩藻吡喃糖基) - 多星果酸。
