In order to fully develop and utilize the new oil resource of Akebia quinata seed,Soxhlet extraction method was used.Single factor experiment and response surface methodology were used to optimize the extraction process.Petroleum ether with boiling range of 30～60 ℃ was selected as the extraction solvent.With the extraction rate as the index,the effects of extraction time,extraction temperature and material liquid ratio on the extraction rate of Akebia quinata seed oil were investigated respectively,and the extraction process under different factor levels was finally determined.The regression model was established and the data were analyzed.The results showed that the three factors affecting the extraction rate of Akebia quinata seed oil were extraction temperature＞extraction time＞material to liquid ratio.The optimum extraction process of Akebia quinata seed oil is as follows:extraction time 3.7 h,extraction temperature 81 ℃,material to liquid ratio(g∶mL)2∶61.At this time,the extraction rate of Akebia quinata seed oil reaches 13.6％.
