Objective To optimize the high-speed shear inclusion process on Schizonepetae Spica volatile oil - β-cyclodextrin inclusion complex. Methods On the basis of single factor test, the inclusion process was optimized by Box-Behnken response surface method with the comprehensive score of inclusion complex yield and pulegone inclusion rate as the evaluation index, and mass ratio of β-cyclodextrin to volatile oil, shear speed, and shear time as the investigation factors. The optimum process conditions were selected by analyzing the interaction of various factors by Design-Expert 13 software. Results The optimum process parameters of preparing Schizonepetae Spica volatile oil - β-cyclodextrin inclusion complex by high-speed shearing method were as following: the ratio of β-cyclodextrin to volatile oil was 8∶1, the mass ratio of β-cyclodextrin to purified water was 1∶8, the shearing inclusion time was 40 min, and the shearing speed was 7 700 r/min. Conclusion The optimized process has high inclusion rate and inclusion yield, and the process is reasonable and feasible, which has a certain guiding role for the research and production of subsequent products.
