Popis:	The partition behaviors of some dyes, anthraquinones, and tanshiones in two kinds of aqueous two-phase systems (ATPSs) have been investigated. The partition constants (K) of ionic dyes and rhein in the first kind of ATPSs are dependent on hydrophobic and electrostatic interactions. A correlation for K as a function of the concentration ratio of total surfactant ions and surface net charge ratio of aggregates between the two coexisting phases has been proposed. Almost 100% of water-insoluble electroneutral extract accumulates in surfactant-rich phase of the first kind of ATPS due to hydrophobic interaction. K of emodin in the second kind of ATPSs is correlated by the same model regardless of electrostatic interaction.
