Abstract: According to forgoing research results, authors analyzed the changing orderliness of the model of extraction technology about extraction ratio with the ratio of solvent to material, extraction temperature and extraction time with response surface methodology(RSM), and optimized the technology. When the ratio of liquid to solid material is 8.02, temperature is 77.20 ℃, time is 4.32 hours, the extraction ratio is up to 92.62%.
