The natural lipids were extracted with hexane in 2.8% yield and resolved into an acidic fraction (28.7%) and a neutral fraction (71.1%). The normal monocarboxylic acids (19.26%), the hydrocarbons (9.94%), the monohydric alcohols (35.53%) and the sterols (5.61%) were isolated from the acidic fraction and neutral fraction by column chromatography. The class compounds were analysed by gas liquid chromatography, Saturated and unsaturated fatty acids ranging from lauric (C12) to cerotic (C26) were present with palmitic acid (C16) being predominant. The n-alkanes range from henocosane (C21) to heptatriacontane (C37) with hentriacontane (C31) as the major product. The n-alkanols range from behenyl (C22) to myricyl (C30) with ceryl (C26) as the maximum, b-Sitosterol was found to be the major component (97.35%) of the sterol fraction.
