6'-O-Coumaroylaloesin from Aloe castanea--a taxonomic marker for Aloe section Anguialoe.
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.
