摘要： 琉璃芭含油量高达3200,其中γ-亚麻酸含量占21%～25%,与多种含不饱和脂肪酸的植物如黑加仑、醋栗、月见草及红加仑等种子相比,琉璃芭种子油中γ-亚麻酸含量最高.γ-亚麻酸具有调血脂、降血压、美容保健、延缓衰老等多项生理功能.琉璃芭全草可食.

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
