花生油与紫苏种子油脂肪酸组分的比较研究—胡彦(GC-MS) . Comparison of Fatty Acid Components Between Peanut Seed Oil and Perilla Frutescens Seed Oil

Abstract

The oil contents and fatty acid compositions of the peanut seeds and Perilla frutescens seeds are studied using methods of chemical extraction and GC/MS analysis.The results shows that oil contents of the peanut seeds and Perilla frutescens seeds are 34.60% and 39.40% respectively.According to the GC/MS analyzing results,eight kinds of fatty acids,linoleic acid,oleic acid,palmitic acid,stearic acid,docosanoic acid,10-octadecenoic acid,eicosanoic acid and 11-eicosenoic acid,are detected in peanut seeds oil; only five kinds of fatty acids,palmitic acid,linoleic acid,α-linolenic acid,stearic acid and 10-octadecenoic acid,are detected in Perilla frutescens seeds oil.The major compositions in the sample of peanut oil are linoleic 53.05% acid,31.74% oleic acid and 7.95% palmitic acid; while those in the sample of Perilla frutescens seeds oil are α-linolenic 80.06% acid,11.83% linoleic acid and 5.37% palmitic acid.The content of unsaturated fatty acids in total fatty acids in peanut seeds oil and Perilla frutescens seeds oil is 85.21% and 92.82% respectively.
