摘要：
The partition behaviour of puerarin in ethylene oxide-propylene oxide random copolymer (EOPO)/K2HPO4/water systems was investigated. The optimum conditions were EOPO (SDP30) 28 %, K2HPO4 24 %, temperature-induced condition was 70 degrees C and 0.5 h. Yield of puerarin could reach 42.26 %. Based on the modified model ln K/R-2 = A* + b*(w ''-w') + c*(w ''- w')(2), partition coefficients of puerarin in EOPO/K2HPO4 aqueous two-phase systems were correlated. It was found that the correlation of the experimental data was quite satisfactory.
