A detailed comparative study between chemical and bioactive properties of Ganod...
Stojković, Dejan; Barros, Lillian; Calhelha, Ricardo C.; Glamočlija, Jasmina; Ćirić, Ana; Van Griensven, Leo J.I.D.; Soković, MarinaA detailed comparative study on chemical and bioactive properties of wild and cultivated Ganoderma lucidum from Serbia (GS) and China (GCN) was performed. This species was chosen because of their worldwide use as medicinal mushroom. Higher amounts of sugars were found in GS, while higher amounts of organic acids were recorded in GCN. Unsaturated fatty acids predominated over saturated fatty acids. GCN revealed ...
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...
Cultivated strains of Agaricus bisporus and A. brasiliensis: chemical character...
Stojković, Dejan; Reis, Filipa S.; Glamočlija, Jasmina; Ćirić, Ana; Barros, Lillian; Van Griensven, Leo J.I.D.; Ferreira, Isabel C.F.R.; Soković, MarinaAgaricus bisporus (J. E. Lange) Emil J. Imbach and Agaricus brasiliensis Wasser, M. Didukh, Amazonas & Stamets are edible mushrooms. We chemically characterized these mushrooms for nutritional value, hydrophilic and lipophilic compounds. The antioxidant and antimicrobial activities of methanolic and ethanolic extracts were assessed. Hepatotoxicity was also evaluated. The ethanolic extract of both species was te...
A comparative study of chemical composition, antioxidant and antimicrobial prop...
Heleno, Sandrina A.; Stojković, Dejan; Barros, Lillian; Glamočlija, Jasmina; Soković, Marina; Martins, Anabela; Queiroz, Maria João R.P.A comparative study on chemical composition (nutritional value, primary and secondary metabolites), antioxidant properties (scavenging activity, reducing power and inhibition of lipid peroxidation), and antimicrobial activity (antibacterial and demelanizing properties) of two samples of Morchella esculenta (morel) from different countries (Portugal and Serbia) was performed. This species was chosen for being on...
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...
Tirmania pinoyi: chemical composition, in vitro antioxidant and antibacterial a...
Stojković, Dejan; Reis, Filipa S.; Ferreira, Isabel C.F.R.; Barros, Lillian; Glamočlija, Jasmina; Ćirić, Ana; Nikolić, Miloš; Stević, TanjaDesert truffle, Tirmania pinoyi (Maire) Malençon from Libya was chemically characterized in nutritional value, primary and secondary metabolites. Antioxidant (scavenging activity, reducing power and inhibition of lipid peroxidation) and antibacterial activity of its methanolic extract alone and in combination with potassium metabisulfite (E224) were evaluated under in vitro conditions. Furthermore, the effect o...
Nutrients and non-nutrients composition and bioactivity of wild and cultivated ...
Stojković, Dejan; Reis, Filipa S.; Barros, Lillian; Glamočlija, Jasmina; Ćirić, Ana; Van Griensven, Leo J.I.D.; Soković, Marina; Ferreira, Isabel C.F.R.Mushrooms have been reported as sources of biomolecules with various potential. Coprinus comatus was studied to obtain information about this species, comparing cultivated and wild samples. Free sugars, fatty acids, tocopherols, organic acids and phenolic acids were analysed by chromatographic techniques coupled to different detectors. C. comatus methanolic extractwas tested for its antioxidant potential (reduc...
Chemical characterization and bioactivity of two different species of wild mush...
Reis, Filipa S.; Stojković, Dejan; Soković, Marina; Glamočlija, Jasmina; Ćirić, Ana; Martins, Anabela; Ferreira, Isabel C.F.R.Mushrooms are widely appreciated all over the world for their nutritional properties, and also for their pharmacological value. They have been considered valuable health foods, being a source of many different bioactive compounds such as unsaturated fatty acids, tocopherols, organic acids and phenolic compounds. The present work reports and compares the nutritional value, bioactive compounds and antioxidant pro...
Chemical constituents and biological activity of Boletus aereus Bull. growing w...
Stojković, Dejan; Ćirić, Ana; Reis, Filipa S.; Barros, Lillian; Glamočlija, Jasmina; Ferreira, Isabel C.F.R.; Soković, MarinaBoletus aereus Bull. is a bolete, an edible mushroom frequently consumed all over the globe as a delicate mushroom, especially in Serbia, Portugal, Basque Country, Navarre, France and Italy. As a member of the Boletaceae family, this mushroom has tubes and pores, instead of gills beneath its cap. B. aereus growing wild in Serbia was chemically characterized in nutritional value and individual compounds (sugars,...
