Summary Solvent‐fractionation used in conjunction with molecular distillation and chromatographic adsorption yielded wax fractions whose separation into their components was successfully and easily accomplished. Without benefit of either molecular distillation or chromatography however, but merely by a solvent‐fractionation procedure there were isolated cerotic acid and melissyl alcohol under conditions which point to their occurrence in ouricuri wax in an ester combination. Column chromatography was found to be a remarkably successful tool in resolving the mixture of hydrocarbons which this wax contains and in establishing the homogeneity of an individual hydrocarbon. Indicated beyond a reasonable doubt is the presence of C 24 and C 32 n paraffins; that of all the four even homologs between these limits is strongly indicated.
