Study on the Extraction Process of Herbs in Compound Shanzha Jiangya Tablets by Orthogonal Design

Objective： To optimal the technology of extraction for compound shanzha jiangya tablets. Method： Orthogonal test was employed for selecting the optimum of extraction technology by colligation score and the contents of hyperosicle and total solid matters in water extraction were used as indexes. Result： Eleven volumes of water, extracting 3 times with two hours for each time was considered the optimum extraction technology of herbs. Conclusion： The considerable extraction rate of active components in the drugs is achieved by applying the selected technology, and the simple method is fit for production.
