  Flavonol glycosides with α-D-aldohexoses from Rhododendron irroratum

  摘要：

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