One new beta-hydroxychalcone, 4-acetoxy-5,2',4',6',beta-pentahydroxy-3-methoxychalcone (1), one new flavanone, 7,3'-dihydroxy-5,4'-dimethoxyflavanone (2) and seven known compounds, 2R,3R-transaromadendrin (3), naringenin-7-O-methylether (4), myricetin (5), quercetin-3-O-rutinoside (6), ursolic acid (7), gallic acid (8) and D-glucose (9) were isolated from the methanolic fruit extract of Cornus mas L. (=Cornus mascula L.), Cornaceae. The structures of the new compounds were elucidated on the basis of extensive spectroscopic methods, including 2D NMR experiments and of known compounds by comparison of physical and spectral data with literature.
