title: [Contributions to the comparative study of the antioxidant potential of some extracts obtained from chamomile flowers].
abstract: Within a complex research regarding the pharmaceutical quality of Chamomillae flos commercialized in the Romanian pharmaceutical network (as well as the food chain), we investigated 9 samples of chamomile "tea" purchased in April/May 2005 in compliance to the European Pharmacopoeia.
  
  
  OBJECTIVE
  Since the vegetal material proved to be very different from the chemical composition point of view we tried to establish the antioxidant activity of some extracts (tinctures and infusions) obtained from the selected plant material.
  
  
  METHODS
  Therefore we studied the scavenging abilities observed against DPPH and the ferrous binding propreties correlating its to the polyphenolic content previously determined in the chamomile extracts.
  
  
  RESULTS
  Surprisingly, the scavenging activity against DPPH indicates similar potential both for the hidro-alcoholic extracts as well as fot the infusions, meanwhile the chelation on the ferrous ion was higher for the tinctures that for infusions and different from one sample to the other.
