Study on extraction process for the icariin of hugu capsule with ultrasonic technology

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.
