Abstract
MesoDyn has been carried out to elaborate the micellar properties of natural surfactant glycyrrhizin which is frequently used in traditional Chinese medicine (TCM). The effect of shear rate on the aggregation behavior of glycyrrhizin has been investigated. The results showed that the critical micelle concentration (CMC) of glycyrrhizin increased with the addition of shear rate. And the glycyrrhizin aggregation transformed from spherical micelle to cylindrical micelle as the increase of shear rate. Furthermore, the aggregation behavior of the as-formed micelle was not stable to the change of shear rate. Removal of shear rate was unable to recover the micelle completely in the changing process of shear rate. The simulation results provide mesoscopic information for the solubilization of poorly water-soluble drug, and at the same time provide guidance for high efficient experiments.
