Abstract
The structure of 6'-O-coumaroylaloesin [2-acetonyl-8-(6-O-coumaroyl-beta-D-glucopyranosyl)-7-hydrox y-5-methylchromone], a mono-ester chromone derivative in which only the 6-position of the glucosyl moiety is esterified, was determined by spectroscopic methods. The compound is a unique chemotaxonomic character restricted to the six species in Aloe section Anguialoe.
摘要
6'-O-香豆酰芦荟素[2-丙酮基-8-(6-O-香豆酰-β-D-吡喃葡萄糖基)-7-羟基-5-甲基色酮]是一种单酯色酮衍生物，其中仅葡萄糖基部分的6位被酯化，其结构通过光谱方法确定。该化合物是一种独特的化学分类学特征，仅限于芦荟属狭叶芦荟组的六个物种。
