The Analysis of Fatty Acids of Dry-Thallus High-Yield ofArachidonic Acid Producing Strain byGas Chromatography and Mass Spectrometry / 分析化学

A high-yield arachidonic acid producing strain (mortierella alpina) was selected with ion implantation. After treating the dry-thallus of high-yield arachidonic acid-producing strain with BF3-CH3CH solution, the fatty acid in dry-thallus of arachidonic acid producing strain were analyzed by gas chromatography and mass spectrometry. The result showed that there were saturated and unsaturated fatty acids in the dry-thallus. The relative content of arachidonic acid is 70.2% in the all fatty acids. In addition, there were oleic acid, linoleic acid and γ-linolenic acid in the dry-thallus.
