Investigation of the fixed oil isolated from the roots of echinops kebericho mesfin

The investigation of the fixed oil of the roots of Echinops kebericho Mesfin [Family Compositae] was carried out for the first time. This study revealed the presence of the following fatty acids: Lauric myristic, myristoleic, palmitic, palmitoleic, stearic, oleic, linoleic, linolinic, arachidic and behenic acids in the saponifiable fraction. The unsaponifiable fraction was found to contain beta-sitosterol, stigmasterol, campesterol, beta-amyrin, lupeol and ursolic acid. The identification of ursolic acid was carried out by spectroscopic methods [H-NMR, 13C-NMR and MS]. The chemotaxonomic value of this study has been discussed
