| Abstract: | To high-efficiency use the seeds of Euscaphis konishii Hayata,n-hexane and heating reflux extraction was used to extract oil from the seeds of E.konishii,and the effects of extraction time,extraction temperature and liquid/solid ratio of n-hexane and E.konishii seed on extraction rate were investigated.Based on the results of single-factor test,Box-behnken response surface design and data analysis were carried out by using Design-Expert 8.0.6 software to further optimize the reflux extraction process of E.konishii seed oil.The results showed that the order of the factors affecting the extraction rate were extraction time,extraction temperature and liquid/solid ratio.The optimal extraction process was heating reflux extraction time 62.04 min,extraction temperature 80.2℃and liquid/solid ratio 10.14∶1(mL∶g).The predicted extraction rate under these conditions was 5.84%and the total extraction rate obtained from verifying test was(5.85±0.001)%,which was close to the predicted value and the relative error was 0.17%,indicating that the response surfaced optimized extraction process of E.konishii seed oil was stable and workable.Meanwhile,by analyzing the oil extracted from seed of E.konishii,the yield of kernel oil was(35.6±0.7)%and the yield of seed coat oil was(2.1±0.15)%,18 fatty acid components were defected,among which the unsaturated fatty acids were 65.52%,and linoleic acid content was up to 45.64%. |
