Evaluation and Characterization of Lipids from Different Parts of Fluted Pumpkin Seeds

I.A. Okoro and C.E. Onyereke    

Abstract: Column chromatography and gas-liquid chromatography were used in the evaluation and characterization of oil extracts from different parts of fluted pumpkin seeds. The results show phospholipids (40-58%), glycolipids (26-36%), free fatty acids (1-6%), free sterols (1-2%), neutral lipids (10-24%) and steryl esters (0.8-4%). The fatty acid profiles showed more than 60% instauration comprising mainly C18 fatty acids. The seed coat oil showed more than 70% saturated. Fatty acids, contributed mainly by C16 and C18 fatty acid. The oil extracts in all the sample showed traces of C18: 3 fatty acids.
