马兰籽油中脂肪酸的不同甲酯化方法与GC_MS分析_姜显光 . Different Esterification Method for Analysis of Fatty Acids in Kalimeris indica Seed Oil by GC-MS

Abstract

Kalimeris indica seed oi1 was extracted by Soxhlet extraction.The fatty acids in Kalimeris indica seed oil were esterified by two methods and analyzed by gas chromatography-mass spectrometry(GC-MS).The components and relative contents of the fatty acids esterified by two methods were compared.The results showed that 16 fatty acids were identified by the first esterification method and 6 fatty acids were identified by Esterification Method 2.The contents of the identified fatty acids accounted for 98.66% and 63.68% of Kalimeris indica seed oil,respectively.The predominant fatty acids of Kalimeris indica seed oil were octadecadienoic acid,octadecenoic acid and Hexadecanoic acid by two esterification methods.
