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.
本发明公开了纯化个别取代的环己-2,4-二烯酮、取代的环己烷-1,3,5-三酮、取代的环戊-2-烯-1-酮和取代的1,3-环戊二酮的方法以及使用它们的组合物。纯化方法包括以下步骤:(a)选择要分离的同分异构体;(b)在特定于所选择的同分异构体的双相溶剂体系中溶解同分异构体混合物,其中所述双相系统的分配系数约为0.5至5.0;(c)将溶解在双相溶剂体系中的混合物进行逆流色谱;以及(d)以基本纯形式分离所选择的同分异构体。
