The separation of unsaturated triglycerides on the basis of degree of unsaturation is achieved by an adsorptive chromatographic process in liquid phase with silane- or alcohol-treated silica gel as the adsorbent. Desorbents in the separation process include ketones, having from 3 to 8 carbon atoms, low molecular weight esters, having from 3 to 8 carbon atoms or p-cymene, or mixtures thereof, alone or mixed with a hydrocarbon diluent. The preferred temperature in the separation column is from 120 DEG -150 DEG C.
