A new compound from Rhododendren anthopogonosides maxim.
A new compound, (2R)-4-phenyl-2-O-[beta-D-xylopyranosyl(1-->6)-beta-D-glucopyranosyl]butane (1), has been isolated from the aerial parts of Rhododendren anthopogonoides, together with two known compounds, fraxin (2), and lyoniside (3). Their structures were determined by means of physico-chemical evidence and spectral analyses, including UV, IR, HR-FABMS, 1H and 13C NMR, and 2D NMR data.
