Optimization of Extraction Technique of Changfukang A Capsule / 中国中医药信息杂志

Objective To optimize the extraction technique of Changfukang A capsule. Methods A RP-HPLC method for Hesperidin was established. With the water extraction rate and Hesperidin as the parameters, the extract condition of Changfukang A capsule was optimized by orthogonal design. Results The optimized extraction technique was as follows: The medicinal material was extracted for 3 times with total 8 times of water, 1.5 hours for each time. Conclusion The optimal preparation prosess was validated to be stable and feasible.
