遏蓝菜种子油理化性质及脂肪酸组成的GC-MS分析 . Analysis of Physicochemical Properties and Fatty Acid Composition of Penny Cress Seed Oil

Abstract

In order to explore the penny cress seed oil's physicochemical properties and fatty acid compositions.The penny cress seed oil is extracted by Soxhlet extraction method and the physicochemical properties are determined.It analyzes its fatty acid composition and relative content by GC-MS.The result shows that the oil content,relative density,acid value,iodine value and saponification value are 43.93%,0.88 g/mL,2.27 mgKOH/g,124.27 I2g/100 g,198.33 mgKOH/g.The penny cress seed oil mainly contains nine fatty acid,erucic acid(31.06%),linoleic acid(24.83%),oleic acid(14.55%),linolenic acid(11.33%),11-eicosenoic acid(4.87%),palmtic acid(5.18%),15-fourteen carbon acid(3.23%) and stearic acid(0.57%).It provides a scientific reference of penny cress as the development and utilization of biomass energy.
