Objective： To explore the optimal clathration process of ultrasonic wave with β-cyclodextrin for Radix Ampelopsis volatile oil. Methods： The products of the oil,the oil-bearing rate and utilization oil were used as comprehensive evaluation indicators to select the technological process by orthogonal design,taking the ratio of the oil to β-cyclodextrin,ultrasonic temperature and time. Results： The optimal technological process of clathration was as follows： the ratio of the oil to β-cyclodextrin was 1： 7,ultrasonic temperature was 60℃ and ultrasonic time was 40 minutes. In this conditions,the products of the oil was 72. 13%,utilization oil was 53.26%,and the oil-bearing rate was 7. 58%. Conclusion： The clathration process of ultrasonic wave with β-cyclodextrin for Radix Ampelopsis volatile oil was simple and feasible.
