【Abstract】 Objective:To investigate the chemical constituents of Phyllanthus urinaria.Method:Various chromatographic techniques were employed for isolation and purification of the constituents. The structures were elucidated by chemical and spectral analyses.Result and Conclusion:Fourteen compounds were isolated and seven of them were identified as corilagin(Ⅰ),rutin(Ⅱ),brevifolincarboxylic acid(Ⅵ),isostrictiniin(Ⅸ),geraniin(Ⅹ),gallic acid(Ⅺ) and ellagic acid (Ⅻ).Compound Ⅵ was found from P. urinaria for the first time and compound Ⅸ was found from genus Phyllanthus for the first time.
