[Contributions to the study of the chemical variability of some Galium album Mill. Populations harvested from wild flora in northern Moldavia].

Unlabelled: 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.

Aim: 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.

Material And 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.
