title: Phenols and flavonoids from the aerial part of Euphorbia hirta.
abstract: OBJECTIVE
  To investigate the chemical constituents of the aerial part of Euphorbia hirta Linn.
  
  
  METHODS
  The chemical constituents were isolated and purified by various chromatographic techniques, and their structures were elucidated on the basis of spectroscopic analysis.
  
  
  RESULTS
  Nine compounds were isolated and identified as scopoletin (1), scoparone (2), isoscopoletin (3), quercetin (4), isorhamnetin (5), pinocembrin (6), kaempferol (7), luteolin (8), gallic acid (9).
  
  
  CONCLUSIONS
  Among them compounds 1-3, 5-8 were found from this plant for the first time.
