β¦ Synopsis
Two new compounds, corialins A (1) and B (2) were isolated from Coriaria nepalensis Wall. These new compounds were established as 7-hydroxy-3-[2,3-acetonide-(3-methylbutane)] coumarin (1) and 3-O-b-D-glucopyranosyl-3,4,5-trihydroxy-1-(3methyl-2-butenyl)-benzene (2), on the basis of 1D and 2D NMR techniques.
