【Abstract】 Aim To investigate the chemical constituents of Phyllanthus urinaria L. Methods Various chromatographic techniques were employed for the isolation and purificat ion. The structure was elucidated by spectral analyses. Results A novel ellagitannin named phyllanthusiin G was isolated, its structure was esta blished as 1-O-galloyl-2-phyllanthoyl-3,6-(R)-HHDP-β-D-gl ucose. Conclusion Phyllanthusiin G is a new compound.更多还原
