Abstract: According to forgoing research results, the changing orderlinesses of the model of purifying technology about crystallization pressure, temperature and time with response surface methodology(RSM) were analyzed, and the technology was optimized. On the conditions of crystallization pressure 22.12 MPa, temperature 32.35 ℃, time 2.17 hours, the purity of puerarin was up to 57.55%.

Key words: supercritical CO2 anti-solvent, puerarin, crystallization technology, optimization
