Key Word Index - Rosa davurica; Rosaceae; (+)-taxifolin-3-O-β-D-apio-D-furanoside; dihydroflavonol apioside; tannin; davuriciin M₁; ellagitannin.Abstract - The structure of a dihydroflavonol glycoside from the roots of Rosa davurica has been characterized as (+)-taxifolin-3-O-β-D-apio-D-furanoside. A new hydrolysable tannin, davuriciin M₁, together with three known hydrolysable tannins, have also been isolated.The structure of new tannin was elucidated by spectroscopic and chemical methods.
