Coumarins from Coriaria nepalensis
Two new coumarins ( 1 ) and ( 2 ), along with seven known coumarins 3 – 9 , were isolated from the leaves and stems of Coriaria nepalensis Wall. The two new compounds were established as 7-hydroxy-6-methoxy-3,8-bis(3-methyl-2-butenyl) coumarin ( 1 ) and 7-hydroxy-6-methoxy-3-(3-methyl-2-butenyl) coumarin ( 2 ), on the basis of 1D and 2D NMR techniques. The known compounds 3 , 6 – 9 were isolated from this plant for the first time.
