Abstract :Two new flavonol derivatives, Geranioside A insert ignore into journalissuearticles values(kaempferol 3-[3-insert ignore into journalissuearticles values(a-rhamnopyranosyl);-4-oxy-5-hydroxy-6-methyl-3,4-dihyropyran-2H- 2-pyranoside]); insert ignore into journalissuearticles values(1); and Geranioside B insert ignore into journalissuearticles values(quercetin 3-[3-insert ignore into journalissuearticles values(a-rhamnopyranosyl);- 4-oxy-5-hydroxy-6-methyl-3,4-dihyropyran-2H-2-pyranoside]); insert ignore into journalissuearticles values(2);, along with 5 known flavonols insert ignore into journalissuearticles values(quercetin insert ignore into journalissuearticles values(3);, kaempferol insert ignore into journalissuearticles values(4);, quercetin 4`-O-b -glucopyranoside insert ignore into journalissuearticles values(5);, quercetin 3-O-b -glucopyranoside insert ignore into journalissuearticles values(6);, and kaemferol-3-O-b -glucopyranoside insert ignore into journalissuearticles values(7););, a gallic acid derivative insert ignore into journalissuearticles values(methyl gallate insert ignore into journalissuearticles values(8););, and a hydrolysable tannin insert ignore into journalissuearticles values(pusilagin insert ignore into journalissuearticles values(9););, were isolated from the aerial parts of Geranium purpureum. The structures of the isolated compounds were elucidated on the basis of UV, IR, and 1D- and 2D-NMR experiments as well as TOF-MS.
