摘要/Abstract

摘要： The partition coefficients of baicalin were measured in ethylene oxide and propylene oxide
(EOPO)/salt aqueous two-phase systemsat 298.15K. It was found that most of baicalin
partitioned into EOPO-rich phase. The partition coefficients of baicalin varied from 10 to
120.The effect of various factors, including tie-line length, salt composition, molecular
weight of EOPO, and solution pH, on the partition behaviorwas investigated in EOPO/salt
systems. Furthermore the partition coefficients of baicalin were correlated using the
modified Diamond-Hsumodel. Good agreement with experimental data is obtained. The average
relative deviations are less than 5.0%.
