摘要
对斜叶梾木种子油的主要理化特性进行了测定,并利用气相色谱质谱联用技术(GC-MS)对种子油的脂肪酸组成进行了分析。结果表明:斜叶梾木种子出油率为7.4%,折光指数为1.48%,相对密度(d204)0.98,酸值(以KOH计)31.90 mg/g,皂化值(以KOH计)201.02 mg/g。脂肪酸组成分析表明,种子油中含7种脂肪酸,其中不饱和脂肪酸5种,质量分数为95.91%;饱和脂肪酸2种,质量分数为3.34%。在所有脂肪酸中亚油酸质量分数最高,为68.29%;其次是油酸,为25.25%。
The experiment was conducted to determine the physicochemical properties of Comus 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 （n ）, 0.98 of relative density （d42） , 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.
