Abstract

Two novel bidesmosidic cycloartane-type glycosides, depressosides C and D were isolated from Corchorus depressus L. Their structures were elucidated as (22R)-16beta,22-epoxy-3beta,26-dihydroxy-9,19-cyclolanost-++ +24E-ene 3, 26-di-O-beta-D-glucopyranoside and (22R,24S)-22,25-epoxy-3beta,16beta,24-trihydroxy-9,19-cyclolano stane 3, 24-di-O-beta-glucopyranoside, respectively on the basis of chemical evidence and detailed spectroscopic studies.

摘要

从圆叶茼麻中分离出两种新型双糖苷型环阿尔廷烷型糖苷，即圆叶茼麻苷C和D。基于化学证据和详细的光谱研究，它们的结构分别被鉴定为(22R)-16β,22-环氧-3β,26-二羟基-9,19-环羊毛甾-24E-烯3,26-二-O-β-D-吡喃葡萄糖苷和(22R,24S)-22,25-环氧-3β,16β,24-三羟基-9,19-环羊毛甾烷3,24-二-O-β-吡喃葡萄糖苷。
