Abstract:
OBJECTIVETo establish the mathematical kinetic model of the components extracted from the Salvia miltiorrhiza.
METHODIn the conditions of ultrasound extracting the course of traditional Chinese medicine, the role of ultrasound intensity is large enough, the proliferation of boundary layer can be infinitesimal, as well as the solute upon the surface of medicine quickly into the main solution, we can assume that the whole process of extraction from the control of proliferation. A mathematical model of dual-frequency ultrasound extraction kinetics based on Fick's second diffusion law was established for traditional Chinese medicine. Based on material size and solid/liquid ratio significant factors.
RESULTWe adopt Origin software to carry out a mathematics simulation, the result showed: simulation graphics and experiment value are very fitting.
CONCLUSIONThis proves that S. miltiorrhiza extraction course accords with ordinary extraction dynamics equation at the dual-frequency ultrasound.
