Investigation Some Physicochemical Properties, Lipids, Glycerides and Fatty acid Composition of Mulberry (Morus Alba L) Seed oil of three Different Regions of Bangladesh

摘要

The physicochemical properties, glycerides, lipids and fatty acid compositions of mulberry (tut) seed oil have been studied. It was observed that tut, a shrub grown well under the soil and climatic conditions of Bangladesh contains 31.41% of orange yellow colored oil. The oil was fractionated into mono, di and triglycerides by silicic acid column chromatography. The triglyceride was varied from 90.08-91.05%, diglyceride from 3.25-4.10% and monoglyceride from 1.47-2.05%. The total lipids were fractionated into three major lipid groups, neutral lipids, glycolipids and phospho-lipids by silicic acid column chromatograpy. The neutral lipid ranges from 92.97-93.10%, glycolipids from 2.12-2.43% and phospholipid from 1.85-1.92% of the total oil of the lipid applied. Saturated and unsaturated fatty acids present in the oil were separated and the amount varied from 15.04-16.28% and 74.29-75.86%, respectively, depending on soil conditions of the areas in which the plant grows. The percentage of fatty acid compositions of the oil were analyzed by GLC and found to contain linoleic acid (74.29%), palmitic acid (10.60%), stearic acid (5.61%) and myristic acid (0.07%).
