GC/MS Analysis of Fatty Acid in Fagopyrum Esculentum Seed Oil

Abstract

Abstract: In this paper, Fagopyrum esculentum seed oil was extracted with petroleum ether. Hydrolyzed and esterified withpotassium hydroxide and methanol. After saponification and esterification the oil was determined by capillary GC/MS. Morethan 50 peaks were separated and twenty-three compounds representing 96.95% of the oil were identified. C18:2 & C18:1 &C16:0 were chief components, and their relative contents exceeds 32.91% and 24.73% and 20.04%.There are no reported aboutodd number carbon atomy fatty acid, 2, 6, 10, 14, 18, 22-Tetracosahexaene, 23S-Methylcholesterol, Stigmast-5-en-3-ol, Stigmast-5, 24-dien-3-ol, Olean-12-en-3-ol, Urs-12-en-3-ol.

Key words: Fagopyrum esculentum, fatty acid, chemical constituents, GC/MS
