Abstract: Application of a reference mixture of natural products for systematic analysis and comparison of the properties of biphasic solvent systems in counter-current/partition chromatography. Because the reference mixture is comprised of compounds with varying polarities, functional groups, and structural features it provides a rational method for mapping the optimal resolution polarity range of a particular solvent system. The mapping of optimal resolution polarity ranges of solvent systems provided for the description of the overall optimal resolution polarity range of a solvent system family, comprised of the same solvents in different proportions. By comparing the reference mixture performance in the individual members of a solvent system family, the solvent system that best functions as the representative of, or portal to, the solvent system families is determined. Use of the reference mixture also afforded a method to compare the overall optimal resolution polarity ranges of solvent system families.
