Four new hydrolyzable tannins and an acylated flavonol glycoside from Euphorbia maculata

Article abstract of DOI:10.1139/v97-088

The structure of a new acylated flavonol glycoside from the leaf extract of Euphorbia maculata was characterized as quercetin 3-O-(2″,3″-di-O-galloyl)-β-D-glucopyranoside. Four new hydrolyzable tannins together with twelve known tannins were also isolated and their structures were established by spectral and chemical means as 1,2,6-tri-O-galloyl-α-D-glucose, 1-O-galloyl-2,4;3,6-di-O-chebuloyl-β-D-glucose (eumaculin E), and dimers (eumaculins B and D) having a tergalloyl and a macaranoyl group as the linking unit of monomers, respectively.
