酸浆果籽油的提取研究

Comparative study on different methods for oil extraction of physalis alkekengi L.seed

研究浸泡法、超声波辅助萃取法和索氏萃取法对黑龙江产酸浆果籽萃取的影响,分别对乙酸乙酯,乙醚和正己烷的提取效果进行比较。结果表明,浸泡法的籽油产率为乙酸乙酯的18.68%、乙醚的17.68%以及正己烷的14.30%;超声波辅助萃取法的油脂产率为乙酸乙酯的18.51%、乙醚的19.55%以及正己烷的17.26%;索氏提取法的油脂产率为乙酸乙酯的19.53%、乙醚的19.70%以及正己烷的18.83%。GC-MS分析表明3种方法获得的果籽油成分均以亚油酸和油酸为主。

The effects of three extracting methods were studied,including conventional solvent extraction（CSE）,ultrasonic wave-assisted solvent extraction（UASE） and Soxhlet＇s extraction（SE）,for oil extraction from Physalis alkekengi L.seed cultivated in Heilongjiang.And the Effects of three extraction solvents were compared,such as ethyl acetate,ether and hexane.The results showed oil yields were ethyl acetate 19.08%（w/w）,ether 17.68% and hexane14.30% by CSE method.ethyl acetate 18.51%（w/w）,ether 19.55% and hexane17.26% by UASE method.ethyl acetate 19.53%（w/w）,ether 19.70% and hexane18.83% by SE method.Analysis of GC-MS showed linoleic acid and oleinic acid were the main constituents of oil obtained.
