Abstract

Tricalysiosides V and W, two new ent-kaurane glycosides with an acylated disaccharide moiety at the C-3 position, were isolated from the roots of Tricalysia okelensis and their structures established by spectroscopic and chemical methods as ent-kauran-3alpha,16alpha,17-triol-19-al 3-O-[5-O-vanilloyl-beta-D-apiopyranosyl(1-->6)]-beta-D-glucopyranoside (1) and ent-kauran-3alpha,16alpha,17-triol-19-al 3-O-[5-O-E-sinapoyl-beta-D-apiopyranosyl(1-->6)]-beta-D-glucopyranoside (2).

摘要

从奥氏三角叶的根部分离出了两种新的对映-贝壳杉烷糖苷——三叶苷V和W，它们在C-3位带有一个酰化二糖部分，通过光谱和化学方法确定其结构分别为对映-贝壳杉烷-3α,16α,17-三醇-19-醛3-O-[5-O-香草酰基-β-D-阿吡喃糖基(1→6)]-β-D-葡萄糖苷(1)和对映-贝壳杉烷-3α,16α,17-三醇-19-醛3-O-[5-O-E-芥子酰基-β-D-阿吡喃糖基(1→6)]-β-D-葡萄糖苷(2)。
