Five flavonoid glycosides having kaempferol 3 , quercetin 4 and myricetin 2 , 5 and 6 skeleton were isolated from leaves of Catha edulis species together with querce tin. The structure of ampelopsin ( 2) , was assigned by combination on 1D and 2D NMR spectroscopy for the f irst time as well as MSESI. While the structures of kaempferol 3-O- β -Glucopyranoside (3) , Quercetin 3-O- β - Galactopyranoside(4) , Myricetin 3-O- β - Glucopyranoside (5) and Myricetin 3-O- β -Xylofuranoside ( 6) were identified by 1 H and 13 C NMR, as well as UV spectroscopy and also confirmed by the spectral dat a of aglycones and TLC of the sugars obtained after acid hydrolysis. Compounds 3 , 5 and 6 were reported for the first time from this plant.
