Polar Lipids of Spinach (Spinacia oleracea) Roots

Authors


Abstract

The polar lipid components in the roots of spinach (Spinacia oleracea) plant were identified as phosphatidylcholine, phosphatidylserine, phosphatidylethanolamine, monogalactosyl-diglycerides, digalactosyldiglycerides, polygalactosyldiglycerides, sulpholipids and three unknown glycosides. Phospholipids constituted only 10% of the polar lipid fraction and 90% was of nonphosphatidic nature. This latter fraction was highly unsaturated and contained linoleic acid as the major fatty acid component.
