Abstract:  A new acylated secoiridoidal glucoside, named gentiorigenoside A (1 ), was isolated from the root of Gentiana rigescens (Gentianaceae) , together with eight known compounds, gentiopicroside ( 2) , 6′- O-β- D-glucopyranosyl gentiopicroside (3) , loganic acid (4 ) , 6′- O-β- D-glucopyranosyl loganic acid ( 5), sweroside ( 6 ), 2′-( o, m-dihydoxybenzyl) -sweroside (7), swertiamarin (8) and secologanoside (9) . heir structures were elucidated on the basis of detailed spectroscopic analysis. Iridoidal glucosides 3, 5 and 9 were isolated for the first time from the title plant.
