Abstract

AbstractThe purified crude lipid of Psoralia corylifolia seeds was subjected to lipid class and fatty acid analysis by thin layer and gas chromatography. The lipid classes identified were triacyl glycerol, free fatty acid, diacyl glycerol, mono acyl glycerol, hydrocarbon‐waxester and polar lipid fractions. Most of the fractions were found to contain high level of C18:1 while C18:0, C18:3 and C20:0 were also found to be present in all the lipid fractions. It has been observed that the diacyl and monoacyl glycerol fractions contain significant amounts of C14:0 and C18:0 while the hydrocarbon‐waxester fraction was rich in C22:0. The polar lipids contain high level of C18:3 and low level of C18:1 as compared to other lipid fractions. The fatty acid composition of the whole oil was also determined and found to be similar to other fractions. Unidentified long chain fatty acids were also present in significant amounts in all the lipid fractions.
