摘　　要：运用单因素试验和响应面试验对超声波辅助石油醚提取奇亚籽油的最佳工艺进行优化。以液固比、超声功率、超声时间为单因素条件,以奇亚籽油得率为评价指标,确定各个因素的最佳水平,同时对奇亚籽油的降血脂功能进行研究。结果表明,奇亚籽油提取的最佳工艺条件为液固比15︰1 (mL/g)、超声时间64 min、超声功率320W。在此条件下,奇亚籽油得率为30.12%±0.19%。经体内降血脂动物试验可知,奇亚籽油能有效抑制高脂血症小鼠的TC、TG、LDL-C含量,升高HDL-C含量,表明奇亚籽油具有一定降血脂功能。该研究为奇亚籽油作用机理的深入研究奠定基础。Study the metabolic effects of chia seed oil extracted from chia seeds on hyperlipidemic mice.The optimal process of ultrasound-assisted petroleum ether extraction of chia seed oil was optimized using one-factor test and response surface test.Liquid-solid ratio,ultrasonic power and ultrasonic time were used as the one-factor conditions,the chia seed oil yield was used as the evaluation index to determine the optimal levels of each factor,and the hypolipidemic function of chia seed oil was also investigated.The results showed that the optimal process conditions for chia seed oil extraction were liquid-solid ratio of 15:1(mL/g),ultrasonic time of 64 min,and ultrasonic power of 320 W.Under these conditions,chia seed oil yield was 30.12%±0.19%.As shown in the in vivo lipid-lowering animal experiments,chia seed oil could effectively inhibit triglyceride(TG),total cholesterol(TC) and low density lipoprotein-Cholesterol(LDL-C) content in hyperlipidaemic mice,and increase the content of HDL-C.Chia seed oil has a certain hypolipidemic function,which lays the foundation for the in-depth study of the mechanism of action of chia seed oil.
