斜叶梾木种子油的理化性质及脂肪酸成分分析（GC-MS） . Physicochemical Properties and Fatty Acid Composition of Cornus obliqua Seed Oil

Abstract

The experiment was conducted to determine the physicochemical properties of Cornus obliqua seed oil and analyzed its fatty acid composition by GC-MS. The oil yield of C. oblique seed oil is about 7.4%. The physicochemical properties of the oil are 1.48% of refraction index( n20D),0.98 of relative density( d204),31.90 mg/g KOH of acid value and 201.02 mg/g KOH of saponification value. Five kinds of unsaturated fatty acids are in seed oil,and the relative content is over 95.91%.Two kinds of saturated fatty acids are in seed oil,and the relative content is 3.34%. The highest relative content of linoleic acid is about 68.29% followed by 25.25% of oleinic acid.
