The neutral lipids were isolated from palm oil from dura and pisifera varieties of Elaeis guineensis grown in India. On examination by TLC, they were found to be composed of triacylglycerols (87.7% and 89.8% respectively), diacylglycerols (4.5%, 3.8%) monoacyglycerols (1.2%, 1.0%), free fatty acids (4.0%, 3.0%) and sterol esters (1.6%, 1.4%), along with hydrocarbons and free sterols (1.0%, 1.0%).

GLC analysis of the sterols and sterol esters revealed the presence of β-sitosterol, stigmasterol, campesterol and brassicasterol, identified by reference to the relative retention time values of the standards. GLC analysis of the triacylglycerols, diacylglycerols, monoacyglycerols, free fatty acids, and sterol esters showed the presence of mainly palmitic and oleic acids, along with some stearic, linoleic and linolenic acids.
