Abstract

Ultrasonic extraction method was used to extract oil from red raspberry seed and then the fatty acid composition of seed oil was analyzed by GC/MS.The results showed that 34 components were determined and 19 fatty acids(accounting for 97.85 % of total oil) were identified.The saturated fatty acids were 11.88 %,in which the content of palmitic acid,stearic acid were 6.74 % and 2.69 %,respectively,while the unsaturated fatty acids were 85.97 %,in which the content of linoleic acid,linolenic acid were 57.42 % and 25.41 %,respectively.
