| Abstract: | Objective To do the research on the extraction technology of Qianyu granules with nonsugar by means of Cortex Phellodendri as the quantization. Methods Adopt the orthogonal experiment to make the optimization and the methods of HPLC to determine the content of the berberine. Results The concentration of the ethanol had a significant effect on the extraction and other factors also had an effect on the extraction. The optimized technology was A3B3C2. Conclusion The optimized technology was that it was reflowing extracted by 85% ethanol which was ten times than the medical material and extracted twice for 300 min each. |
