Abstract
A new approach was suggested for the analysis of total marine oil acids without isolation of individual components. The techniques of lithium soap-acetone segregation, molecular distillation, reversed-phase partition chromatography and urea complex fractionation were applied in the successive subdivisions of pilchard acid fractions. Relatively simple mixtures of acids were obtained; the composition of one of which was calculated without isolation of an individual component. The techniques employed were such as might be expected to have caused little or no modification of the component acids.
