毛乌素沙地牛心朴子种子中脂肪酸成分的GC_MS分析_贝盏临 . Analysis on Fatty Acids Composition of Maowusu Desert Cynanchum komarovii Al.by GC-MS

Abstract

Objective:To extract and analyse the composition of fatty acid in Cynanchum komarovii Al.seeds.Methods:By soxhlet extraction from Cynanchum komarovii Al.seeds extract fat-soluble composition,gas chromatography-mass spectrometry detecting its chemical composition.Results:the 15 fatty acid were separated and identified from Cynanchum komarovii Al.seeds,and amount to the total fractions of chromatographic peak area 99.39%.Mainly for linoleic acid(0.79%),linolelaidicacid(0.21%),oleic acid(Z)-(2.11%),elaidic acid(58.85%),linolenic acid(0.32%),Heptadecanoic acid(0.45%),Hexadecanoic acid,14-methyl-(2.17%),Octadecanoic acid(7.8%),Hexadecanoic acid(9.12%),palmitoleic acid(17.11%).Conclusion:In Cynanchum komarovii Al.seeds,fatty acid mainly was unsaturated fatty acid,and the main fatty acids was elaidic acid and palmitoleic acid.
