Technical Abstract: Dietary sterols have received much attention recently due to their ability to reduce serum cholesterol in humans and animals. Sterols also have reported antitumor-promoting and anti-inflammatory activities. The sterol and fatty acid composition of lentils (Lens culinaris) were studied using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Sterols were derivatized with BSTFA:TMCS (99:1) and chromatographed as their TMS derivatives. Beta-Sitosterol was the major sterol in lentils, comprising about 68% of the total sterols. Campesterol, stigmasterol and beta-amyrin were also identified. Palmitic, steric, oleic, linoleic and linolenic acids, determined as their methyl esters, were identified in lentils. Details on the concentration of these constituents will be presented.
