[Study on the extracting and dried process of Qinxiangzhixie enteric-coated tablet].

To study the optimum extracting and dried process of Qinxiangzhixie enteric-coated tablet.With the content of Aesculin and Aescaletin as factor, the optimum extraction process was selected with the orthogonal design.The optimum extraction process conditions were as: decocting for 2 times, with water of 8, 6 times of the drug mixture respectively 1.5 h, 1.0 h respectively. The optimum decompression dried process conditions was as follows :60 degrees C, -0.08 pa.The experimental results provide the basis for the ascertainment of extraction process of Qinxiang enteric-coated tablet.
