title: [Physico-chemical characterisation of Zn-flavonols complexes].
abstract: The aim of flavonols complexation is to improve their specific activity.
  
  
  METHODS
  The flavonols sources were Morus alba L. and Morus nigra L., zinc being the biological active ion. Physico-chemical characterization was made by thin-layer chromatography, UV-VIS spectrophotometry, IR spectrometry and polarography.
  
  
  RESULTS
  The complexes results were within acceptability limits, but their obtaining is economically inefficient.
