白芥子油的提取研究

The Extraction of Mustard Seed Oil

采用索氏提取法提取了内蒙产白芥子的白芥子油。结合单因素考察和正交试验优化了提取条件，确定白芥子油的最佳提取条件为：石油醚（沸程60～90℃）作为提取剂，提取温度为95℃，提取时间为4 h ，白芥子质量浓度为0．125 g/mL。实验结果表明：在最佳提取条件下，白芥子油提取率可达35．4％。GC/MS分析结果表明：白芥子油的脂肪酸主要由油酸、亚油酸、亚油酸和芥酸组成。

The mustard see d oil was obtained by Soxhlet extraction with the seed origin from Inner Mongolia .According to single factor and orthogonal test ,the optimum extraction condition is as follows ：petroleum ether （distillate range 60-90 ℃） used as extraction solvent ,extraction temperature 95 ℃ ,extraction time 4 h ,mustard seed mass concentration is 0 .125 g/mL .Under these conditions the extraction rate reached to 35 .4% .Mustard oil fatty acid composition was analyzed by GC/MS .It mainly contained by erucic acid ,oleic acid ,linoleic acid and linolenic acid .
