摘　　要：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.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.
