Abstract

Two new flavan glycosides, (2S)-5,7,4'-trihydroxyflavan-7-O-β-D-glucopyranoside and (2S)-5,7,4'-trihydroxyflavan-5-O-β-D-glucopyranoside, and a new neolignan, (7S,8S)-3-methoxyl-3'-O-β-D-glucopyrannosyl-4':8,5':7-diepoxyneolignan-4,9'-diol, were isolated from the leaves of Liquidambar formosana Hance. Their structures were elucidated on the basis of spectroscopic data and chemical evidence.

摘要

从枫香树（Liquidambar formosana Hance）的叶子中分离出两种新的黄烷糖苷，即(2S)-5,7,4'-三羟基黄烷-7-O-β-D-吡喃葡萄糖苷和(2S)-5,7,4'-三羟基黄烷-5-O-β-D-吡喃葡萄糖苷，以及一种新的新木脂素，即(7S,8S)-3-甲氧基-3'-O-β-D-吡喃葡萄糖基-4':8,5':7-二环氧新木脂素-4,9'-二醇。根据光谱数据和化学证据对它们的结构进行了阐明。
