Abstract

As the glycosyl constituents of Ficus pumila L. fruits (Moraceae), three new sesquiterpenoid glucosides, pumilasides A, B and C were isolated together with benzyl beta-D-glucopyranoside, (E)-2-methyl-2-butenyl beta-D-glucopyranoside and rutin. Their structures were characterized as (1S,4S,5R,6R,7S,10S)-1,4,6-trihydroxyeudesmane 6-O-beta-D-glucopyranoside, (1S,4S,5S,6R,7R,10S)-1,4-dihydroxymaaliane 1-O-beta-D-glucopyranoside and 10 alpha, 11-dihydroxycadin-4-ene 11-O-beta-D-glucopyranoside by spectral and chemical methods.

摘要

作为薜荔果实（桑科）的糖基成分，分离得到了三种新的倍半萜糖苷，即薜荔苷A、B和C，以及苄基β-D-吡喃葡萄糖苷、（E）-2-甲基-2-丁烯基β-D-吡喃葡萄糖苷和芦丁。通过光谱和化学方法，它们的结构被鉴定为（1S，4S，5R，6R，7S，10S）-1，4，6-三羟基桉叶烷6-O-β-D-吡喃葡萄糖苷、（1S，4S，5S，6R，7R，10S）-1，4-二羟基马兜铃烷1-O-β-D-吡喃葡萄糖苷和10α，11-二羟基杜松-4-烯11-O-β-D-吡喃葡萄糖苷。
