A new method for the qualitative analysis of fats has been devised by using paper chromatography. The method employed involves the oxidative decomposition of fat by potassium permanganate in the acetone solution, esterification of the acidic oxidation products, preparation of their hydroxamic acid derivatives, and final paper chromatographic separation of these acids. [Cf. INouYE and NODA: This Journal, 23, 294, 368 (1950); 24, 291, 295 (1951)] The hydroxamic acids prepared from the oxidation products of each fat give a characteristic chromatogram, in which the appearance of spots differs from that of other fats, because the amount and kind of the lower carboxylic acids produced by oxidation are restricted within specific range according to each, on account of the peculiarity of structures and proportions of the component fatty acids of original fat. It seems that this method can be utilized for the qualitative analysis of fats as a new interesting method.
