| Abstract: | Gas chromatography-mass spectrometry(GC-MS) was used to analyze fatty acid compounds from silkworm pupa oil which was extracted by Soxhlet method and modified to methyl esters,and cured golden thread meat by NIST MS spectral library searching and alignment ofspectral data.A total of 8 kinds of fatty acid compounds were identified.The components are quantitatively determined by norm alization method,which consisted of myristic acid(0.20%),arachidonic acid(0.27%),palmitic acid(16.84%),palmitoleic acid(2.40%),... |
