In addition, a further study was made of the technique of extraction, isolation and purification of GLA. The factional extraction used in the laboratory with n-hexane and ethanol was changed into the whole extraction of 6〓 solvent, which simplified production technique and reduced cost of production. The fungal lipid extracted from the fermentation in the medium-scale test was concentrated by the urea adducting method with methanol as solvent, at 75～80℃ for 3 hours. After GLA had been adducted twice, the content of GLA came up to 84. 25%, around a twelfth as much as the original concentration.
