To optimize the preparation of total saponins of Aralia taibaiensis phospholipid complex( TSAT-PC) by the central composite design-response surface method.
Total saponins of Aralia taibaiensis phospholipid complex was prepared by using solvent evaporation method, five factors including reaction solvent, reaction time, reaction temperature, ratio of reactants on this reaction, and the concentration of the drug were investigated, then to optimize the preparation of TSAT-PC by the central composite design response surface method, and to study its physicochemical properties.
The optimal process conditions were as follows, the reaction time was 1 h, the reaction temperature was 45 ℃,the ratio of soya lecithine ( SL) and TSAT was 3∶ 1, the reaction concentration was16 mg / m L, the complexing rate was 97. 23%,it was less than 5% with the predicted deviation; IR analysis proved the formation of TSAT-PC, and the solubility in the octyl alcohol was higher than the original drug.
TSAT-PC was successfully developed by the optimized process, enhance the solubility in octyl alcohol, which provide the reference for the further development and utilization of Chinese materia medica preparation.
