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.
