LIPID-COMPOSITION OF PERILLA SEED

The composition of lipids and oil characteristics from perilla [Perilla frutescens (L.) Britt.] seed cultivars are reported. Total lipid contents of the five perilla seed cultivars ranged from 38.6 to 47.8% on a dry weight basis. The Lipids consisted of 91.2-93.9% neutral lipids, 3.9-5.8% glycolipids and 2.0-3.0% phospholipids. Neutral lipids consisted mostly of triacylglycerols (88.1-91.0%) and small amounts of sterol esters, hydrocarbons, free fatty acids, free sterols and partial glycerides. Among the glycolipids, esterified sterylglycoside (48.9-53.2%) and sterylglycoside (22.1-25.4%) were the most abundant, while monogalac tosyldiacylglycerol and digalactosyldiacylglycerol were present as minor components. Of the phospholipids, phosphatidylethanolamine (50.4-57.1%) and phosphatidylcholines (17.6-20.6%) were the major components, and phosphatidic acid, lysophosphatidylcholine, phosphatidylserine and phosphatidylinositol were present in small quantities. The major fatty acids of the perilla oh were linolenic (61.1-64.0%), linoleic (14.3-17.0%) and oleic acids (13.2-14.9%). Some of the physicochemical characteristics and the tocopherol composition of perilla oil were determined.
