摘要:

以新疆野生苍耳籽为材料,采用溶剂法萃取其籽油脂,通过单因素和正交试验研究提取时间、料液比、提取温度工艺参数对苍耳籽油提取率的影响,并用GC-MS 法测得其脂肪酸的含量及组分。结果表明:野生苍耳籽油的最佳提取工艺条件为提取时间2.5h、料液比1:10(g/mL)、提取温度75℃;野生苍耳籽油脂含量为22.14%,油脂以不饱和脂肪酸为主要成分,其中亚油酸相对含量85.73%、油酸相对含量7.67%、棕榈酸相对含量3.76%、硬脂酸相对含量1.35%。本方法可作为苍耳籽油的提取工艺。

Abstract:

Soxhlet extraction was used to extract oil from the seeds of Xanthium sibiricum Patrin wildly grown in Xinjiang. The effects of extraction time, solid/liquid ratio and extraction temperature on oil yield were studied by single factor and orthogonal array design methods. Besides, the fatty acid composition of the extracted oil was measured by GC-MS. The results showed that the optimal values of the above parameters affecting oil yield were determined to be: extraction time 2.5 h, solid/liquid ratio 1:10 and extraction temperature 75 ℃. Under such conditions, the oil yield was 22.14%. Xanthium sibiricum Patrin seed oil contained mainly unsaturated fatty acids, and the relative contents of linoleic acid, oleic acid, palmitic acid, stearic acid were 85.73%, 7.67%, 3.76% and 1.35%, respectively.

Key words: Xanthium sibiricum Patrin seed oil, extraction rate, composition of unsaturated fatty acids
