摘要
采用新型酯化法，仅１０ｍｉｎ即完成油中各脂肪酸的甲酯化．用尿素络合法从玻璃苣油中分离出高浓度γ－亚麻酸甲酯，经用石墨化碳黑作为载体涂层制备出的ＤＥＧＳ（丁二酸二乙二醇聚酯）ＰＬＯＴ玻璃毛细管柱进行ＧＣ分析，纯度达９３％以上．为获得ｒ－亚麻酸标准品提供了一条可靠的途径．
In the paper,bring to success methyl esterification of fatty acid in oil in the short space of tenminute by new technique of ester. Having separated high concentrated metyl r-linolenic from Borago offici-nalic L. by urea complexing. Examination by gas chromatography of DEGS.PLOT glass capillary columncoated with graphitized carbon black confirmed that the purity of r-linolenic was up to 93.1389%.For ob-tain standard material of r- linolenic supplied a reliable way.
