ABSTRACT
The preparation process of Xiaoyaosan Oral Liquid was investigated with the orthogonal test. As a result,the amount of water added was a main factor influencing the dip-extraction effect of crude Chinese medical materials when the oral liquid was made with the method of distillation and warm dip. It was suggested that the following process would be the best to ensure the extraction of active compo- nents:adding 10 times amounts of water,then dipping and extracting for 1.5h at 90℃ and repeating 3 times.
