中文摘要：

摘要以文冠果籽为原料，利用热盐水法提取文冠果籽油。通过响应面法优化提取工艺，建立影响文冠果油提取率的因素与响应值之间的数学模型，并采用GC-MS分析其脂肪酸组成。结果表明：当搅拌转速40r／min，NaCl加入量10％，料液比1：3．5（g：mL）时，油脂提取率可达70．06％，与模型高度拟合；GC—MS分析确定文冠果中主要含8种脂肪酸，其中必需脂肪酸亚油酸含量高达42．83％。

英文摘要：

With the Xanthoceras sorbifolia seeds oil was extracted via hot salt water method. Mathematical model between the primary factors and respond value was built by respond surface method and GC-MS fatty acid composition analysis. The results showed that when the stirring speed was 40 r/min, the dosage of NaC1 was 10% , material liquid ratio was 1：3.5 （g： mL） , the oil extraction rate can reach to 70.06% and it is highly consisted with the mathematical model; GC-MS analysis showed that the seed oil mainly contained 8 fatty acids. Among them, linoleic acid, one es- sential fatty acid was up to 42.83%.
