Abstract

In addition to lotaustralin and linamarin, a novel cyanogenic glycoside, 2-((6-O-(beta-D-apiofuranosyl)-beta-D-glucopyranosyl)oxy)-2-met hylbutanenitrile , two novel non-cyanogenic glycosides, (2S)-((6-O-(beta-D-apiofuranosyl)-beta-D- glucopyranosyl)oxy)butane and 2-((6-O-(beta-D-apiofuranosyl)-beta-D-glucopyranosyl)oxy)propane, and a simple non-cyanogenic glycoside, ethyl beta-D-glucopyranoside, were isolated from an ethanolic extract of the fresh root cortex of Manihot esculenta. From a methanolic extract of the fresh leaves of this species lotaustralin and linamarin, and two flavonoid glycosides, kaempferol-3-O-rutinoside and quercetin-3-O-rutinoside were isolated.

摘要

除了洛塔斯澳苷和亚麻苦苷外，还从木薯新鲜根皮的乙醇提取物中分离出一种新型氰苷，2-((6-O-(β-D-阿吡喃呋喃糖基)-β-D-吡喃葡萄糖基)氧基)-2-甲基丁腈，两种新型非氰苷，(2S)-((6-O-(β-D-阿吡喃呋喃糖基)-β-D-吡喃葡萄糖基)氧基)丁烷和2-((6-O-(β-D-阿吡喃呋喃糖基)-β-D-吡喃葡萄糖基)氧基)丙烷，以及一种简单的非氰苷，β-D-吡喃葡萄糖苷乙酯。从该物种新鲜叶子的甲醇提取物中分离出洛塔斯澳苷和亚麻苦苷，以及两种黄酮苷，山奈酚-3-O-芸香糖苷和槲皮素-3-O-芸香糖苷。
