超声提取护骨胶囊中淫羊藿苷的工艺研究

Study on Extraction Process for the Icariin of Hugu Capsule with Ultrasonic Technology

目的:采用正交试验方法研究护骨胶囊(HG)的最佳超声提取工艺。方法:以淫羊藿苷含量作为考察指标,采用正交试验法对超声功率(A)、超声频率(B)、药液比例(C)及超声时间(D)4个因素进行考察,分析最佳提取条件。结果:护骨胶囊中淫羊藿苷的最佳超声提取条件为:超声功率为120 W,超声频率为28 KHz,药液比例为1∶35,超声时间为10 min。结论:该超声提取工艺具有简便、快速、耗能低等特点,在最佳工艺条件下淫羊藿苷含量可比传统提取法高1.8倍。

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 caiTied 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 ieariin is 1.8 times higher than that of the traditional extraction method.
