title: Flavonol glycosides with alpha-D-aldohexoses from Rhododendron irroratum.
abstract: Two new flavonol glycosides which contain rare alpha-D-galactose or alpha-D-glucose were obtained from the flowers of Rhododendron irroratum Franch., namely myricetin 3-O-beta-D-galactoside-3'-O-alpha-D-glucoside (1) and myricetin 3-O-beta-D-galactoside-3'-O-alpha-D-galactoside (2). Their structures were determined by UV, IR, HR-ESI-MS, ESI-MS, 1D- and 2D-NMR techniques.
