Glycosides H and I, the structures of which were established by modern physicochemical analytical methods (PMR, 13C NMR, COSY, TOCSY, HMBC, MS) and acid-base hydrolysis, were isolated from the purified total saponins from fruit of Phytolacca americana containing at least 10 triterpene glycosides by rechromatography of enriched fractions over a column of silica gel. Glycoside H was a bidesmoside of
用现代理化分析方法(PMR、13C NMR、COSY、TOCSY、HMBC、MS)和酸碱水解建立了糖苷H和I的结构,它们是从美洲商陆果实中纯化的总皂苷中分离出来的,其中含有通过在硅胶柱上对富集馏分进行再色谱分离,得到至少 10 种三萜糖苷。Glycoside H 是 phytolaccageninic 酸的一种双糖苷,较早从 Phytolacca acinosa 的细胞培养物中分离出来。糖苷 I 是 3-O-(β-D-吡喃木糖基-(1 → 3)-β-D-吡喃半乳糖基-(1 → 3)- β-D-吡喃木糖基)-28-O- β-D-吡喃葡萄糖基植物漆,这是我们第一次孤立。
