[en] We have tried to establish some criteria to avoid the substitution of Veronica officinalis L; with anti-ulcer and anti-inflammatory activities with other species of the genus Veronica, especially Veronica chamaedrys L. widely spread and without therapeutic use. We have studied the different histological, anatomical and phytochemical characters for the two species. A rapid method for the identification of both species is the TLC for flavonoids and phenylpropanic compounds was described. Moreover HPLC is useful to detect the presence of acteoside only in Veronica chamaedrys, while Veronica officinalis contains isoacteoside.
