Abstract:
Objective To optimize a preparation technique of Pingfenggujin Granule. Methods The technique was determined by the orthogonal design with content of Astragalosides, polysaccharides and the rate of dried extracts. The contents of polysaccharides and Astragalosides were determined by UV and ELSD-HPLC respectively. Results The optimum water-extraction technique was to steep 2.5 h, ten times of water as much as weigh of total drugs and extract three times, 2 h each. Conclusion The optimum technique is feasible, and the method of content determination is accurate and reliable.
