title: Isolation and identification of a novel ellagitannin from Phyllanthus urinaria L.
abstract: OBJECTIVE
  To investigate the chemical constituents of Phyllanthus urinaria L.
  
  
  METHODS
  Various chromatographic techniques were employed for the isolation and purification. The structure was elucidated by spectral analyses.
  
  
  RESULTS
  A novel ellagitannin named phyllanthusiin G was isolated, its structure was established as 1-O-galloyl-2-phyllanthoyl-3,6-(R)-HHDP-beta-D-glucose.
  
  
  CONCLUSIONS
  Phyllanthusiin G is a new compound.
