The constituents were extracted by some solvents. 18 constituents were isolated from Chloroform fraction by different chromatography. 15 constituents were identified by IR ,MS and NMR as follows: 3-sitosterol, P-sitosterylpalm itate,succinate acids, 1, 4-benzenediol, 1, 2-benzenediol, p-hydroxybenzaldehyde, syringaresinol, oleanolic acid, usolic acid, ethyl caffeate , Rosmarinic acid ethylster and etc. In such constituents ,nine compounds were isolated for first time from Origanum vulgare L..
