A method for the purification of substituted cyclopent-2-en-1-one congeners and substituted 1,3-cyclopentadione congeners from a complex mixture using countercurrent separation

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