Abstract

The conditions for extracting oil from Malania oleifera Chun kernel assisted by microwave were studied.The effect of solvent types,microwave power,extraction time and ratio of material to solvent on the oil yield were discussed through single factor and orthogonal experiments.The results showed that the optimal solvent was ligarine(60-90℃),and the optimal conditions were as follows: ratio of material mass to solvent volume 1∶8,extraction time 150 s,microwave power 600 W.Compared with Soxhlet extraction,the yield of oil with microwave-assisted extraction method increased by 2.1% and the microwave-assisted extraction time was only the 1/280 of Soxhlet extraction time.Fatty acids in the Malania oleifera Chun oil were analyzed by GC-MS,and fifteen components were separated,in which eleven ones were identified and determined.There were 90.67% components identified.
