Isolation and identification of a novel ellagitannin from Phyllanthus urinaria L.
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.
