Two new flavonol derivatives, Geranioside A (kaempferol  3-[3-(a-rhamnopyranosyl)-4-oxy-5-hydroxy-6-methyl-3,4-dihyropyran-2H-  2-pyranoside]) (1) and Geranioside B (quercetin 3-[3-(a-rhamnopyranosyl)-  4-oxy-5-hydroxy-6-methyl-3,4-dihyropyran-2H-2-pyranoside])  (2), along with 5 known flavonols (quercetin (3), kaempferol (4),  quercetin 4'-O-b -glucopyranoside (5), quercetin 3-O-b  -glucopyranoside (6), and kaemferol-3-O-b -glucopyranoside (7)), a  gallic acid derivative (methyl gallate (8)), and a hydrolysable tannin  (pusilagin (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.
