Methods of purifying individual congeners of substituted cyclohexa-2,4-dienones, substituted cyclohexane-1,3,5-triones, substituted cyclopent-2-en-1-ones, and substituted 1,3-cyclopentadiones and compositions using the same are disclosed. The purification method includes the steps of: (a) selecting a congener to be isolated; (b) dissolving the mixture of congeners in a bi-phasic solvent system specific to the selected congener to be isolated, wherein said bi-phasic system has a partition coefficient from about 0.5 to 5.0; (c) subjecting the mixture dissolved in the bi-phasic solvent system to a counter current chromatography; and (d) isolating the selected congener in substantially pure form.
