Abstract
Two flavonoid allose diglycosides were found in the terrestrial part of Tha lictrum squarrosum St. ex Willd. and T. minus L. (Ranunculaceae). 7,4'-Di-O -beta-allopyranosylapigenin was isolated from T. minus. In T. squarrosum, i ts monoacetate was also found and characterized as 7-O-(6-O-acetyl-beta-all opyranosyl)-4'-O-(beta-allopyranosyl)apigenin. The sites of attachment of t he carbohydrate residues were determined by HMBC; the location of the aceta te group was identified by ROESY. Both substances were isolated from these plants for the first time.
