| 摘 要： | 对采自湖南保靖白云山的华榛种仁,采用超声波提取法提取种仁油脂,设计正交实验比较不同超声强度、提取时间、溶剂种类、料液比对提取率的影响,获得最佳提取工艺条件为:以石油醚为溶剂,料液比1:9,超声强度250 W,提取时间30 min,油脂提取率为57.84％,所得油脂橙黄清亮.利用气相色谱-质谱( GC - MS)联用技术对油脂脂肪酸成分及含量进行分析,得出油酸69.54％,亚油酸16.09％,9-十六碳烯酸0.22％,棕榈酸9.01％,硬脂酸4.44％,11-二十烯酸0.24％,花生酸0.23％,2-己基环丙烷辛酸0.14％,十七烷酸0.09％,其中不饱和脂肪酸含量高达86.09％,具有较高的应用价值.

| Abstract: | The seed kernels of Corylus chinensis Franch collected from Baiyun mountain in Baojing county of Hunan Province in China were assessed.Ultrasonic extraction method was used to extract the oil from seed kernel of Corylus chinensis Franch,and the effects of ultrasound intensity,extraction time,solvent sorts,solid-liquid ratio on extraction rate were studied by orthogonal test.The optimum conditions were determined as follows:petroleum ether used as extractant,extraction time 30 min,ultrasound intensity 250 W,... |
