Among them, forty-four were identified as braylin, toddanin, 7-hydroxycoumarin, angustifolin, scopoletin, coriarintin A, coriarintin B, coriarintin C, coriarintin D, coriarintin E, demethylramosinin, 7-hydroxy-3,8-bis(3-methyl-2-butenyl) coumarin, corianin, tutin, coriamyrtin, corinterin A, methyl gallate, gallic acid, ellagic acid, 3,4'-O-dimethylellagic acid, 3,3'-O-dimethylellagic acid, 3,3'-O-dimethylellagic acid-4'-O-��-glucopyranoside, 3,3'-O-dimethylellagic acid-4'-O-��-xylopyranoside, methyl 2-(4-hydroxyphenyl) acetate, tetracosyl (E)-ferulate, coriamedin A, coriamedin B, ��-sitosterol, stigmasterol, ergosta-7,22-dien-3��-ol, ��-sitosteryl 3-O-��-D-glucopyranoside, (24R)-24-ethylcholesta-4,22-dien-3-one, ursolic acid, oleanolic acid, 20-epibryonolic acid, 5-hydroxymethyl-2-furanocarboxaldehyde, coriamedin C, succinic acid monobutyl ester, (R)-dimethylmalate, 2,6-dimethoxybenzoquinone, squalene, brevifolin, glyceryl-1-tetracosanoate. Among them, ten compounds neamed coriarintin A, coriarintin B, coriarintin C, coriarintin D, coriarintin E, corinterin A, corinterin B, coriamedin A, coriamedin B and coriamedin C were new compounds. Demethylramosinin and 7-hydroxy-3,8-bis(3-methyl-2-butenyl) coumarin were reported for the first time from the natural sources. Their structures were determined by 1H, 13C, 2D NMR, MS, UV-Vis and IR spectral analyses. The known compounds were identified by comparison of their physical and spectral data with those reported in the literature.
