【摘要】 以r-亚麻酸甲酯为原料可合成二高-r-亚麻酸,再经生物合成得前列腺素E₁。本文报道了由月见草（Oenothera biennis）种子油制备 r-亚麻酸甲酯的方法。所得产品为无色或微带黄色的油状液体,含有 r-亚麻酸60%（GLC）以上。按月见草油计算,总收率约3%。更多还原

【Abstract】 Dihomo-γ-Linolenic acid was obtained chemically using methyl γ-linolenate as starting material.It could then be converted into prostglandin E₁ through bio- synthesis.In this paper,a modern method for preparing methyl γ-linolenate from the seed oil of Oenothera biennis was reported.The product obtained was a col- ourless or light yellowish oil.The content of γ-linolenic acid was higher than 60%（GLC）.The total yield was about 3% caculated on the weight of the seed oil.更多还原
