Abstract: Objective：To extract Schizonepeta Volatile Oil from Herba Schizonepetae with steam distillation method,optimize the extraction process and inclusion process. Methods：The weight of Schizonepeta Volatile Oil was taken as the observation index，water adding volume，soak time and extraction time were taken as three main factors．L9(34) orthogonal test was adopted to optimize the best extraction process．The proportion of β－cyclodextrin and oil, the amount of extraction solvent and time as factors ,to optimize the best inclusion process．Results：The best extraction process: 12 times of water adding volume，3 h soaking，2 h extraction．The best inclusion process: the proportion of β－cyclodextrin and oil was 1:10, the amount of solvent was 3 times,grinding time was 15min．Conclusion：The optimum processes are simple,steady and attainable, can be used as industrial production process.
