从云南‘雨林牌’血竭 Dracaena cochinchinensis(Lour.) S. C. Chen中分高鉴定了一个 新的酚苷:3,4-二羟基烯丙基苯4-O一[α-L-鼠李吡喃糖基(1-6)-β-D-葡萄吡喃糖苷,2个已知的 甾体皂苷:26-O-β-D-葡萄吡喃糖苷-呋甾烷-5,20(22),25(27)-三烯-1β,3β,26-三醇-1-O[a-L-鼠 李吡喃糖基(1→2)]-a-L-阿拉伯吡喃糖苷和26-O-β-D-葡萄吡喃糖基-呋甾烷-5,25(27)-二烯-1β, 3β,22β,26-四醇-1-O-[a-L-鼠李吡喃糖基(1→2)]-a-L-阿拉伯吡喃糖苷,它们的结构是根据光谱数 据和物理方法确定的。

[Abstract]
A new phenolic glycoside:3,4-dihydroxyallylbenzene 4-O-[a-L-rhamnopyranosyl(1→6)]-(β-D-glucopyranoside was isolated from the Yulin Brand Xuejie of the Chinese Dragon's Blood,Dracaenacochinchinensis (Lour.)S. C. Chen,together with two known steroidal saponins:26-0-β-D-glucopyranosyl-furostan-5,20 (22),25 (27)-triene-1β, 3β, 26-triol-l-O-[α-L-rhamnopyranosyl (1→2)}-a-L-arabinopyra-noside and 26-0-β-D-glucopyranosyl-furostan-5 .25 (27)-diene-1β, 3β, 22β. 26-tetraol-l-O-[a-L-rhamnopy-ranosyl (1→2)}-α-L-arabinopyranoside. Their structures were identified by spectral data and physical meth-ods.
