  The decrease of the surface of natural ecosystems, to which can be added the climatic changes from the last decades, have lead to a reduction of the areas where some species have grown, and, on the other hand, to the decrease of intra- and inter specific genetic variability. The aim of this project is to contribute to the protection the biodiversity of the Veronica species. These studies will contribute to the biodiversity conservation but also to its reconstruction in areas where it was affected already by the anthropogenic impact. Veronica is the most species-rich genus of family Plantaginaceae. In the spontaneous Romanian flora 41 species of Veronica have been reported. The genetic diversity (Albach et al., 2004) of the species, and the chemical composition used for phytotherapy (Crisan et al., 2009), have encouraged different types of research to be carried out on these species with the practical aim of including them in breeding programs, especially the V. officinalis species. A characterization, with the Geographic Information System (GIS) of the habitat conditions from two protected areas - Ceahlau National Park and Apuseni Natural Park - was carried out. By analyzing the comprehensive digital maps, significant differences between the habitat conditions of the two protected areas have been identified. Knowing the value and importance of the V. officinalis species for phytotherapy, and also the antropic preasure maintained on it as source of active pharmacological compounds, a comparative biochemical screening of different Veronica species, in order to identify alternative species with comparable biosinthetic spectra to be used as alternative sources was performed. The biochimical fingerprint of the V. officinalis species was characterized through HPLC-MS for polyphenols and iridoids. In Veronicae officinalis herba, the free polyphenols are found in small quantities since their biggest part are present as esters; the esters of the ferulic acid are present in the biggest quantity. For the first time in our country the quantitative determination of aucubin and catalpol in V. officinalis was carried out.
