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

ABSTRACT

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
