Abstract

Two new dimeric hydrolyzable tannins named eumaculin A (1) and eusupinin A (2) have been isolated from Euphorbia maculata L. and Euphorbia supina RAFIN., and their structures elucidated. Twelve other polyphenolic compounds including five hydrolyzable tannins and five flavonol glycosides have also been isolated.
