摘要:首先采用不同溶剂提取花椒油,确定石油醚为最佳提取溶剂。在此基础上,通过正交试验
对花椒籽油的提取工艺进行了优化,结果得出最佳的工艺条件为:以石油醚为提取溶剂,在料液比
1 ∶ 13 ,提取温度 60 ℃下,提取 2 次,每次 2 h。在此工艺条件下,花椒籽油的提取率达到 90 %以上。
同时利用气相色谱对花椒籽油的脂肪酸组成进行了测定,结果表明,花椒籽油中以油酸和亚油酸含
量最高,最少为棕榈油酸。

Abstract :Prickly ash seed oil wa s fir st extracted by different solvents to determine the optimal one , a nd the
re sult showed that petrole um ether was the best. Af ter t hat , o n the basis of single factor experiment , the
orthogo nal test was used in optimization of technological parameter s. The optimum technological condition
was that prickly ash see d wa s e xtracted by petroleum ether at the ratio of 1 ( material) ∶ 13 (petroleum e2
ther) and 60 ℃for 2 times and 2 hour s per time , unde r which the extracted rate co uld be as high as 90 %.
