In this paper we combined three chromatographic separation and purification technique such as affinity chromatography, ion exchanger chromatography and hydrophobic interaction chromatography to develope a new technology of stimutaneous extraction of three enzyme from pancreatin. We optimized the technology by studying the methods of purification and assured the technology as: The crude extraction from the dissolution of Pancreatin is directly absorbed on the DEAE gelose fast flow columnEquilibrating buffer is 0.01mol/L NaoAc-HoAc buffer(pH4.5; eluting buffer is 0.2~0.35mol/LNaCl in 0.01mol/LNaoAc-HoAc buffer (pH4.5), and then be eluted by two steps to acquire the peak of kallikrein.The solution which can"t be adsorbed by DEAE gelose fast flow column is adsorbed on affinity chromatographic column Equilibrating buffer is 0.01mol/LTris-HCl buffer(pH7.5, eluting buffer is 0.5mol/LNaCl in 0.01mol/Ltris-HCl buffer(pH7.5)and then be eluted by one step to acquire the peak of trypsin.The solution which can"t be adsorbed by is pretreated with 30%~80%(NH_4)_2SO_4 fractional precipitation, the deposition of the precipitation is dissolved to beabsorbed on phenyl gelose fast flow columnhydrophobic interaction chromatography condition is Equilibrating buffer is lmol/L(NH_4_2SO_4 in 0.01mol/LNaoAc-HoAc buffer(pH4.5), eluting buffer is 0~0.6mol/L(NH_4)_2SO_4 in 0.01mol/LNaoAc-HoAc buffer (pH4.5) and then be eluted by two steps to acquire the peak of chymotrypsin.

The sizes of the self-assembly micelles of the amphiphilic block copolymers and the effects werestudied by dynamic light scattering and UV-visible spectrophotometer. The micelle sizes werelargely influenced bythe hydrophobic chain content in the copolymer, the properties of the solvent and the copolymer concentration in the organic phase. The morphology of the micelles was investigated by transmission electron microscopy. Theresults showed that the micelles appeared spheres with inner core and outer shell. The critical association concentrations were determined by pyrene monomer fluorescence probe technology. The degradability of copolymer was studied by the loss of the intrinsic viscosity in the degradation process. The results indicated that the degradation rate of PECL was slower thanthat of PELLA and PEDLLA. The stability of the copolymer micelle dispersion was examined by measuring the critical flocculation concentration, which gradually decreased with increasing the content of thehydrophobic chain in the copolymer. The rheological results showed thatthe viscosity ofthe micelle dispersion with higher content of PEG segments was firstly decreased and then increased with the increasingthe temperature. Otherwise, the variation of viscosity was irregular. The viscosity of the micelle dispersion increased with the increase of the electrolyte (Na 2SO 4) concentrations. Polymer micelles paclitaxel was prepared by self-emulsification/solvent evaporation method and solid dispersion technique with amphiphilic block polymers as the carrier material.
