title: [Contributions to the study of the chemical variability of some Galium album Mill. Populations harvested from wild flora in northern Moldavia].
abstract: Within a complex research regarding the chemical intra- and inter-specific variability of some medicinal plants, we compared two species of Galium: Galium verum L. and Galium album Mill.
  
  
  OBJECTIVE
  In the present study, we quantified some secondary metabolites from 7 natural populations of Galium album Mill., harvested from Suceava and Neamţ districts, during July 2008.
  
  
  METHODS
  The chemical investigations used TLC, UV-VIS spectrophotometry and HPLC, in order to analyze the composition in iridoids, flavones and polyphenolic acids.
  
  
  RESULTS
  Our study revealed the existence of important chemical variations between the different populations (Râşca, Crucea/ Borca, Runc, Târzial). Meanwhile the harvesting moment within the vegetative cycle plays a major role for the further quality of the product.
