Introduction: Veronica beccabunga L. belongs to the class dicotyledons, order Lamiáles, family Scrophulariaceae. Representatives of the genus Veronica have long been used in folk medicine as antiinflammatory, antibacterial, antiseptic, wound healing, hemostatic, choleretic and antispasmodic drugs. Widely studied species are Veronica officinalis and Veronica chamaedrys. Veronica beccabunga L., which is the object of our study, remains a poorly studied plant. Aim: The study of external signs, microscopy and chemical composition of medicinal plant materials of Verоnica beccabunga L. herb. Materials and Methods: Chromato-mass spectrometry was used in the work. Results and Discussion: When describing external signs and microscopy, diagnostic signs of Verоnica beccabunga were revealed. 27 compounds were identified by chromatography-mass spectrometry. The maximum content falls on: Citronellol epoxide (R or S) (30.5 %), Linolenic acid, ethyl ester (15.18), Diethyl succinate (12.17%), Ethyl palmitate (6.43%), Phytol (4.89%), Acetaldehyde ethyl amyl acetal (3.94%), Dibenzylamine (3.01%), Oleamide (2.77%), 2-(1-Methylbutyl)oxirane (2.7%), Butyl octyl phthalate(1.7%), Ethyl 10-bromodecanoate (1.68), Valeric acid, 4-methyl-, ethyl ester (1.58). Glycoside detected : 1-Benzyl-1Hbenzimidazole 3-oxide (0.76%). Conclusion: The revealed morphological and anatomical signs of Verоnica beccabunga herb can be used to diagnose this species and develop authenticity indicators for promising medicinal herbs. 27 compounds were identified by chromatographymass spectrometry. Using the method of simple normalization, the relative percentage of identified compounds was determined.
