The fatty acid composition of the seed fat of Taraktogenos kurzii has been investigated by carrying out the preliminary resolution of the mixed fatty acids into 13 fractions by low‐temperature crystallisation followed by urea adduction and by subsequent identification of the component acids of each fraction by paper chromatography. The presence and the quantity of linoleic acid has been established by ultra‐violet spectrophotometry. The composition of the mixed fatty acids as established in the present work consists of chaul‐moögric 21.0%; hydnocarpic 19.6%; palmitic 5.8%; myristic 5.9%; gorlic 26.6%; oleic 11.3% and linoleic 4.4%. A gel‐like substance of unestablished composition amounting to 5.4%, probably a mixture of partially polymerised/oxidised unsaturated acid was also obtained. The results agree with those of earlier workers for the percentages of chaul‐moögric, gorlic, oleic and palmitic acids concerned, but not of hydnocarpic acid. The presence of linoleic and myristic acids in this seed fat has been established for the first time.
