| Abstract: | Objective: To optimize the extraction process of Phyllanthus urinaria L. Method: The optimum extraction condition was investigated by the orthogonal design in flavonoids content as index. Results: The factors influencing extraction efficiency were as follows:D>A > B> C (A:Concentration of ethanol, B:The amount of ethanol added, C:Time of extraction, D:Times of extraction). The optimum extraction condition was: extracting the drug for 3 times, every time for 2 hour, after adding 8 fold of ethanol, utilizing concentration of ethanol for 70% .Conclusion: The optimized process is stable and high efficient. |
