Insights into the phenolic composition and in vitro bioactivity of cardoon capi...
Mandim, Filipa; Pinela, José; Marcelino, Sandra Andreia; Dias, Maria Inês; Barracosa, Paulo; Ivanov, Marija; Soković, Marina; Santos-Buelga, CelestinoThe capitulum constituents (stigma, corolla, bracts, pappus, and receptacle) of seven cardoon cultivars were studied for their polyphenolic composition and bioactive properties. Fifteen phenolic compounds were identified, secoiridoid, secoxyloganin, and apigenin-O-hexuronoside in higher concentrations. The bracts had the highest concentration of phenolic compounds, and the corolla had the greatest variety. The ...
A comparative study of lactarius mushrooms: chemical characterization, antibact...
Kostić, Marina; Ivanov, Marija; Fernandes, Ângela; Calhelha, Ricardo C.; Glamočlija, Jasmina; Barros, Lillian; Soković, Marina; Cirić, AnaMushrooms are valued worldwide for their nutritional, organoleptic and chemical properties. The aim of this study was to determine the chemical composition (free sugars, organic acids, fatty acids, tocopherols and phenolic compounds) and bioactivity of three wild mushrooms (Lactarius piperatus, Lactarius quietus and Lactarius vellereus) from Serbia. Chemical analysis was performed with HPLC-RI and UFLC-PDA (for...
Light conditions affect the growth, chemical composition, antioxidant and antim...
Halabura, Marisangela Isabel Wietzikoski; Avelino, Katielle Vieira; Araújo, Nelma Lopes; Kassem, Adma Soraia Serea; Seixas, Flávio Augusto VicenteThe mycelial biomass of basidiomycetes is a promising source of compounds and represents an alternative for industrial and biotechnological applications. Fungi use light as information and hold photoresponse mechanisms, in which sensors respond to light wavelengths and regulate various biological processes. Therefore, this study aimed to investigate the effects of blue, green, and red lights on the growth, chem...
Purple tea: chemical characterization and evaluation as inhibitor of pancreatic...
Silva, Tamires Barlati Vieira; Dias, Maria Inês; Pereira, Carla; Mandim, Filipa; Ivanov, Marija; Soković, Marina; Ferreira, Isabel C.F.R.A variety of the classic green tea plant, Camellia sinensis, was developed and is exclusive to Kenya. Due to high content of anthocyanin polyphenols in its leaves, the beverage obtained from this variety is purple in color and is the origin of the name purple tea. This work had two main purposes. The first one was to identify and quantify the major anthocyanin polyphenols in a hot water aqueous extract of the p...
Evaluation of antimicrobial and antioxidant activities of alginate edible coati...
Lopes, Ana I.; Melo, Adma N.F.; Caleja, Cristina; Pereira, Eliana; Finimundy, Tiane C.; Afonso, Tiago B.; Silva, Sara; Ivanov, Marija; Soković, MarinaPlant extracts (PEs) are natural substances that perform interesting bioactivities. However, they have some limitations. In this work, PEs from licorice, eucalyptus, sage, and thyme were produced and characterized. These extracts showed good bioactive properties. Alginate-based edible coatings and films incorporated with the extracts were produced and their antimicrobial and antioxidant properties were determin...

Tripleurospermum inodorum – mayweed without scent but with range of bioactivities
Ivanov, Marija; Božunović, Jelena; Dias, Maria Inês; Calhelha, Ricardo C.; Barros, Lillian; Ferreira, Isabel C.F.R.; Stojković, DejanTripleurospermum inodorum (L.) Sch. Bip. (Asteraceae), scentless mayweed, is a common weed species, but despite its abundancy it is still underexplored in the terms of its bioactivities. The aim of the study was to explore the bioactivities of scentless mayweed methanolic extract including antimicrobial, antibiofilm, antioxidant, cytotoxic, and antiinflammatory activity and to provide deeper insight into its ch...
Attalea speciosa mesocarp flour in-depth characterization and its application f...
Souza, M.V.S.; Saldanha, Ana Luísa; Pereira, Carla; Ivanov, Marija; Soković, Marina; Steinmacher, Nádia Cristiane; Dias, Maria Inês; Barros, LillianNon-conventional food plants (NFPs) present themselves as a viable and efficient alternative for replacing the food products we consume today. Presenting a huge nutritional, chemical, physical, and biological potential, these plants are usually abundant and not competitors with other vegetable matrices used for human consumption.1 Attalea speciosa (Mart. Ex Spreng - Babassu) is a palm tree from the botanical fa...
Bioactive compounds and functional properties of herbal preparations of Cystus ...
Mocan, Andrei; Fernandes, Ângela; Calhelha, Ricardo C.; Gavrilas, Laura; Ferreira, Isabel C.F.R.; Ivanov, Marija; Barros, Lillian; Babotă, MihaiThe members of Cystus genus are perenial shrubs with a well-established use in traditional medicine. Among these, C. creticus is the most popular, herbal preparations obtained from its aerial parts being recognized as antimicrobial, antitumor and anti-inflammatory agents. The present study aimed to evaluate phytochemical profile and bioactive potential of aqueous and hydroethanolic extracts of C. creticus aeria...
