Rezumat:

In the study regarding the chemical composition of 5 Veronica species (V. urticifolia, V. austriaca, V. officinalis, V. chamaedrys, V. beccabunga), originating from habitats with reduced anthropization from the area surrounding the Moldavian Subcarpathians, we achieved a general phytochemical analysis to identify the big groups of active principles. By means of TLC and HPLC we analyzed the polyphenolic components, spectrophotometrically dosing the flavonoids, iridoids and polyphenolic acids.

With the Veronica populations, we noticed the qualitative and quantitative variability of the polyphenolic acids and flavonoids, dependent on the analyzed species and the original habitat. The HPLC analysis confirmed the presence in some extracts of the derivates of apigenin, luteolin as well as caffeic acid [1]. Similarly, we noticed the existence of an inter- and intra-specific variability of the iridoids and polyholosides.
