A unusual flavone glycoside named Shamimarin (1) and a new compound Acetoxy-8-methyl-chromen-2H-one (2) were isolated from aerial parts of Rhododendron lepidotum L. Along with four known coumarins daphnin (3), daphnetin 8-O-β-D-glucopyrano-side (4), daphnetin (5) and umbelliferone (6). The structural elucidations were based on analyses of chemical and spectroscopic data by including ID and 2D NMR analyses.
