Abstract
Five flavonol glycosides, kaempferol 3,7-di-O- α -L-rhamnopyranoside (1) , isorhamnetin 3,7-di-O- α -L-rhamnopyranoside (2) , kaempferol 3-O- β -D-glucopyranoside-7-O- α -L-rhamnopyranoside (3) , isorhamnetin 3-O- β -D-glucopyranoside-7-O- α -L-rhamnopyranoside (4), Kaempferol 3-O- β -xylopyranosyl-(1'''→2'')-O- α -L-rhamnopyranoside-7-O- α -L-rhamnopyranoside (5), have been isolated from the aerial parts of Reseda arabica. Their structures were established on the basis of physical and spectroscopic analysis, and by comparison with the literature data.
