Phenolic profile, antibacterial, antimutagenic and antitumour evaluation of Ver...
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...
Phenolic profiling of Veronica spp. grown in mountain, urban and sand soil envi...
Barreira, João C.M.; Dias, Maria Inês; Živković, Jelena; Stojković, Dejan; Soković, Marina; Santos-Buelga, Celestino; Ferreira, Isabel C.F.R.Veronica (Plantaginaceae) genus is widely distributed in different habitats. Phytochemistry studies are increasing because most metabolites with pharmacological interest are obtained from plants. The phenolic compounds of V. montana, V. polita and V. spuria were tentatively identified by HPLC-DAD-ESI/MS. The phenolic profiles showed that flavones were the major compounds (V. montana: 7 phenolic acids, 5 flavone...
Antibacterial activity of Veronica montana L. extract and of protocatechuic aci...
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...
Comparative evaluation of antimutagenic and antimitotic effects of Morchella es...
Stojković, Dejan; Davidović, Slobodan; Živković, Jelena; Glamočlija, Jasmina; Ćirić, Ana; Ferreira, Isabel C.F.R.; Soković, MarinaMorchella esculenta (L.) Pers. methanolic extracts, obtained from fruiting bodies growing wild in Serbia and Portugal, were screened for their antimutagenic properties and compared to protocatechuic acid, previously identified in both species. Salmonella typhimurium TA100 reversion assay was used for the antimutagenic properties. Methanolic extracts expressed important antimutagenic potency towards S. typhimuri...
