Abstract: | Commercial rapeseed lecithin has been analyzed after separation by silicic acid column chromatography. Besides neutral oil
(40%), four major constituents have been found, viz., phosphatidyl ethanolamine (18%), phosphatidyl inositol (8%), phosphatidyl
choline (16%) and sterol glycosides (8%). Among the minor fractions lysophosphatidyl ethanolamine accounts for about 2%. The
phosphatides are characterized by low erucic acid content and the major fatty acids are palmitic, oleic and linoleic acids. |
