Objective To optimize the processing technology of Atractylodis Macrocephalae Rhizoma prepared by rice-washed water rinsing, and provide a scientific basis for producing specification in processing. Methods Design the processing with central composite design-response surface methodology and take the factors of volume of rice-washed water, rinsing time, and rinsing temperature as independent variables. The contents of atractylenolide I, Ⅱ, and Ⅲ were determined by HPLC and the comprehensive scores of the three components were regarded as the response index or OD. By analyzing with Design Expert, the best processing parasite for the experiment could be induced. Results The best processing conditions were 9-time volume of rice-washed water, 55 h for rinsing, and at the temperature of 26℃. On the selected condition, the value of OD was at 0.960. Conclusion The rice-washed water rinsing processing technology for Atractylodis Macrocephalae Rhizoma is stable and feasible under the condition selected, which can be used as reference for its production and quality control.
