17:0)甲酯作為內(nèi)標(biāo)物,對γ-亞麻酸進(jìn)行了定量分析。結(jié)果表明,月見草種子油中γ-亞麻酸的含量占11.23%。;A method of capillary GC for the determination of fatty acids in oil of Oenothera odorata was reported. The oil was extracted by chemical method. Fatty acids in the oil was saponified by KOH-MeOH and trans-formed to methyl esters by means of BF3-MeOH,under TLC surveillance.The methyl esters obtained were separated and determined by a Rtx-5 quartz capillary column,(30 m X 0.25 mm. WCOT. fixative fluid 5% Biphenyl-95% dimethyl polysiloxane). γ-Linolenic acid in the oil was determined with methyl heptadecanoate as internal standard. The contents of γ-linolenic acid in the oil sample was found to be 11.23%."/>
