摘要
(3R)-3,4-Dihydro-6,8-dihydroxy-3-(2'-acetyl-3'-O--d-glucopyranosyl-5'-hydroxyphenyl)methyl-2(1H)-benzopyran-1-one (feralolide-3'-O-- d -glucopyranoside, 1), feralolide (2), aloe-emodin (3), feroxidin (4), and chlorogenic acid (5) were isolated from the 70% EtOH extract of flowers of Aloe arborescens. Structures of these compounds were elucidated on the basis of physical and spectral data. Absolute structure of 1 was determined on the basis of circular dichroism spectra for the first time.
