    The sperm whale oil was divided into several fractions by the column chromatography as shown in Table 2 and the components eluted were checked by thin-layer chromatography (Fig. 1). Fatty acids obtained from the waxes fraction (b, c and d1) and the glycerides fraction (d3, e and f1) were subjected to gas-liquid chromatography, respectively. The results are shown in Table 3.
    Mean carbon numbers of fatty acids in both waxes and glycerides are same and unsaturated fatty acids are contained more in waxes. Concentrations of myristic, palmitoleic and oleic acids in waxes are same as those of glycerides, respectively. Lauric, tetradecenoic and eicosenoic acids are more in the former, but palmitic and docosenoic acids more in the latter. Major components fatty acids are in the order as given in Table 4. Oleic acid is dominant both in waxes and glycerides. The order of eicosenoic and palmitoleic acids or that of docosenoic and palmitic acids is found to be reversal in the both fractions.

    The acetone-soluble lipids were obtained from the head cavity, blubber and meat of a sperm whale and fractionated into hydrocarbons, waxes, glycerides and polar substances by column chromatography (Tables 1-3). Fatty alcohols of waxes and fatty acids of both waxes and glycerides were analyzed by gas-liquid chromatography, respectively (Tables 4-6).
    The waxes fraction amounts to 79.4% in head cavity oil, 85.5% in blubber oil and 60.4% in meat oil, suggesting the overall presence of waxes in the sperm whale body. The alcohol or fatty acid compositions of waxes and glycerides are found to be considerably different according to the part of a body.
    Alcohols in waxes of head cavity are characterized by the high concentration of cetyl alcohol exceeding 50% and a series of alcohols having less carbon atoms in a small quantity. Waxes from blubber and meat oils are similar in the alcohol composition, in which oleyl alcohol is dominant.
    In each test oils, the pattern of fatty acids composing waxes shows some similarity to those composing glycerides. Abundance of fatty acids having comparatively less carbon atoms and less double bonds in head cavity oil and occurrence of higher fatty acids in meat oil, especially highly unsaturated ones in waxes, are noticeable.

    Many reports 1-9) so far-published on the compositions of fatty acids and fatty alcohols of sperm whale oil were based on fractional distillation, except one14) in which gas-liquid chromatography (GLC) was applied to the analyses of sperm whale alcohol.
    The present study was undertaken to establish the analytical method of fatty acids and fatty alcohols in sperm whale oil by GLC. Peaks in chromatogram were tentatively identified by comparison of their retention time with those of the synthesized reference substances including members with odd numbers of carbon atoms (Table 1), by behavior following hydrogenation (Figs. 2 and 3), and by use of a plot of logarithm of retention time vs. carbon chain length (Fig. 1).
    The relative responses of methyl esters and acetyl esters for the thermal conductivity detector were calibrated by using a mixture of synthesized reference substances and were used for correction of peak area.
    The compositions of fatty acids and fatty alcohols were determined on several kinds of sperm whale oil listed in Table 2 and the results are given in Tables 7 and 8. No marked difference was observed among the specimens from different places of catch, but the present data are a little lower in the concentrations of major components than those reported in the past, probably due to the presence of components with odd numbers of carbon atoms. Beaked whale oil revealed higher concentration of eicosenic acid and oleyl alcohol and the concent-ration of palmitic acid and cetyl alcohol was lower than that contained in sperm whale oil. Also the beaked whale oil contained docosenol which was found be absent in sperm whale oil.
