Partition Behavior

The partition behavior of Puerarin in ethylene oxide-propylene oxide random copolymer (EOPO)/ K2HPO4/water systems was investigated .The optimum conditions were EOPO （SDP30） 28%, K2HPO424%, temperature-induced condition was 70°C and 30min. yield of Puerarin could reach 42.26%. Based on the modified model lnK/R2=A*+b*(w”-w’)+c*(w”-w’)2, partition coefficients of Puerarin in EOPO/K2HPO4aqueous two-phase systems were correlated. It was found that the correlation of the experimental data was quite satisfactory.

PEG/ ammonium sulfate aqueous two-phase systems were supplied to separate GMP. It was found that PEG molecular weight, PEG concentration and ammonium sulfate concentration could influence the partitioning of GMP. The data of experiment showed that 18% (w/w) PEG6000 and 15% (w/w) ammonium sulfate were the optimum system, in which the protein recovery was 69.2%
