中文摘要: 以橡胶籽为原材料，通过超声波辅助溶剂法提取橡胶籽油。以橡胶籽油提取率为考察指标，在单因素试验的基础上，选取料液比、超声功率、超声时间、超声温度进行响应面优化试验；采用气相色谱法测定橡胶籽油脂肪酸组成。结果表明：石油醚提取效果最好，料液比1∶12.4（g/mL）、超声功率306 W、超声时间47 min、超声温度45.7℃，在此条件下橡胶籽油提取率可达 42.80%。橡胶籽油主要是由棕榈酸（C16∶0）、硬脂酸（C18∶0）、油酸（C18∶1）、亚油酸（C18∶2）和 α-亚麻酸（C18∶3）组成，不饱和脂肪酸含量达到 79%以上。
Abstract:With rubber seed as material，rubber seed oil was extracted by ultrasonic-assisted solvent extraction method.On the basis of single factor test，material-liquid ratio，ultrasonic power，ultrasonic time and ultrasonic temperature were optimized by response surface method（RSM），rubber seed oil extraction rate as evaluation index；The fatty acids composition was determined by gas chromatography（GC）.The research showed that petroleum ether was the best，the premium parameters for rubber seed extraction were the material-liquid ratio 1∶12.4 （g/mL），ultrasonic power was 306 W，ultrasonic time for 47 min，ultrasonic temperature was 45.7℃.Under this circumstance，the rubber seed oil extraction rate of polyphenols could reach 42.80%.Results showed that major fatty acids were palmitic acid（C16∶0），stearic acid（C18∶0），oleic acid（C18∶1），linoleic acid（C18∶2）and α-linolenic acid（C18∶3）and the content of unsaturated fatty acids was more than 79%.
