Özet
Two new flavonol derivatives, Geranioside A (kaempferol 3-[3-(alpha-rhamnopyranosyl)-4-oxy-5-hydroxy-6-methyl-3,4-dihyropyran-2H-2-pyranoside]) (1) and Geranioside B (quercetin 3-[3-(alpha-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-beta-glucopyranoside (5), quercetin 3-O-beta-glucopyranoside (6), and kaemferol-3-O-beta-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.
