Živković, Jelena; Barreira, João C.M.; Stojković, Dejan; Cebovic, Tatjana; Santos-Buelga, Celestino; Maksimović, Zoran; Ferreira, Isabel C.F.R.This study was designed to characterize the phenolic profile and evaluate the antibacterial, antimutagenic and antitumor activities of Veronica urticifolia Jacq. methanolic extract. HPLC-DAD/ESI-MS analysis revealed the presence of phenolic acids, flavonoids and phenylethanoids, with acteoside as the main component (14.9 mg/g of extract). Antibacterial effect was determined using the microbroth dilution assay a...

Stojković, Dejan; Živković, Jelena; Soković, Marina; Glamočlija, Jasmina; Ferreira, Isabel C.F.R.; Janković, Teodora; Maksimović, ZoranThis study was designed to evaluate the antibacterial activity of the Veronica montana L. water extract and its main phenolic compound, protocatechuic acid. The antibacterial activity was determined by microdilution assay against six strains of Gram-positive and Gram-negative bacteria. Listeria monocytogenes was the most sensitive of the tested bacterial species. Antibacterial preserving properties of protocate...
Phenylethanoid glycosides in Veronica urticifolia extracts: characterization by...
Barreira, João C.M.; Stojković, Dejan; Maksimović, Zoran; Živković, Jelena; Santos-Buelga, Celestino; Ferreira, Isabel C.F.R.Veronica (Piantaginaceae) is a genus of 450 species found in temperate regions of both hemispheres. ln this work, the aerial parts of Veronica urticifolia were collected during flowering period from Mountain Goc in central Serbia. Powdered samples (1 g) were extracted twice with methanol:water 80:20 (v/v). After removing solvents, the combined extracts were re-dissolved in 20% aqueous methanol, filtered through...
