| 摘 要： | 采用索氏抽提法提取圆锥梾木种仁油,分析了种仁油理化指标,并利用气相色谱质谱联用技术(GC-MS)对油的脂肪酸组成进行了分析。结果表明:圆锥梾木种仁出油率为7.0%,折光指数为1.4804,相对密度0.98,酸值(KOH)39.46mg/g,皂化值(KOH)175.94mg/g。经GC-MS分析鉴定,圆锥梾木种仁油检出11种脂肪酸成分,检出率99.70%。其中,饱和脂肪酸4种,含量占比为7.51%,不饱和脂肪酸7种,含量占比92.19%,未知成分0.3%。

| Abstract: | The Cornus racemosa seed kernel oil was obtained by Soxhlet extraction,and its physical and chemical indexes were analyzed.The fatty acid composition was identified by gas chromatography-mass spectrometry(GC-MS).The results showed that the seed kernel oil production rate of C.racemosa seeds was 7.0%,with refractive index of 1.480 4,relative density of 0.98,acid value(KOH)of 39.46 mg/g,saponification value(KOH)of 175.94 mg/g.The results of GC-MS analysis showed that there were 11 kinds of fatty acids determined from the seeds oil,with detectable rate of 99.70%.Among them,there were 4 kinds of saturated fatty acids,accounting for 7.51%,and 7 kinds of unsaturated fatty acids,accounting for 92.19%. |
