Abstract: The borage seed,containing 32% of fatty acids(FA) was extracted for getting from its oil 22.55% γ-linolenic acid (GLA),After separations through methods of urea occlusion and AgNO3-SiO2 column chromatograghy, GLA contents can reach 80.4% and 93.7% respectively.The GLA content in products was determined by gas chromatograghy after esterification with iodomethane.The effects of urea,Ag+ and temperature during the separation process were discussed.When urea/FA=3:1,t=2℃ in the urea occlusion and AgNO3/(SiO2+AgNO3)=6%,the best separation of GLA from borage seed oil may be obtained.
Key words: borage, γ-linolenic acid.purification, urea occlusion, chromatograghy
