[Studies on chemical constituents of Phyllanthus urinaria L].

To investigate the chemical constituents of Phyllanthus urinaria.Various chromatographic techniques were employed for isolation and purification of the constituents. The structures were elucidated by chemical and spectral analyses.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.
