    Abstract:
    OBJECTIVE: To study the best ultrasonic technology of the extraction of icariin of Hugu capsule. METHODS: Used the content of icariin as index, orthogonal experiment was carried out to investigate 4 influential factors as follows: the ultrasonic power (A), the ultrasonic frequency (B), the material fluid ratio (C), the time (D). RESULTS: The best extraction conditions were as follows: the ultrasonic power was 120 W, the ultrasonic frequency was 28 KHz, solid-liquid ratio of 1 : 35, the extraction time was 10 min. CONCLUSION: Optimization of extracting process is simple, quick and low energy consumption. Under these conditions, the extraction of icariin is 1.8 times higher than that of the traditional extraction method.
