title: Flavonoids from Glycyrrhiza pallidiflora hairy root cultures.
abstract: Three flavonoids named licoagrosides D, E and F together with four known flavonoids, medicarpin 3-O-glucoside, calycosin 7-O-glucoside, formononetin 7-O-(6"-malonylglucoside) and 2'-hydroxyformononetin 7-O-glucoside were isolated from Glycyrrhiza pallidiflora hairy root cultures. Their structures were determined on the basis of spectroscopic evidence. Licoagrosides E and F are the first examples of a 6a-hydroxypterocarpan glycoside and an alpha-O-glycosidic alpha-hydroxydihydrochalcone, respectively.
