摘要

从龙脑香叶中分离出一种新的呋喃甾醇苷（1）以及螺甾-5,25(27)-二烯-1β,3β-二醇 1-O-α-L-吡喃鼠李糖基-(1→2)-α-L-吡喃阿拉伯糖苷（2）。通过光谱分析 1D 和 2D NMR 以及质谱分析（正向模式 HR-ESI-MS），阐明了 1 的结构为 (25R)-26-O-β-D-吡喃葡萄糖基-22α-甲氧基-5α-呋喃甾-1β,3β,26-三醇-1-O-β-吡喃葡萄糖苷。

A New Furostanol Glycoside from Dracaena cambodiana

A new furostanol glycoside (1), along with spirosta-5,25(27)-dien-1β,3β-diol 1-O-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranoside (2), were isolated from the leaves of Dracaena cambodiana. The structure of 1 was elucidated as (25R)-26-O-β-D-glucopyranosyl-22α-methoxy-5α-furost-1β,3β,26-triol-1-O-β-Dglucopyranoside, which was determined by spectroscopic analysis 1D and 2D NMR, and mass spectroscopy (HR-ESI-MS in positive mode).
