Phenolic Profile and Antioxidant and Biological Activities of Plant Extracts Ri...
Melo, Adma N.F.; Afonso, Tiago B.; Pedrosa, Mariana C.; Carvalho, Marta; Rodrigues, Cláudia; Dias, Maria Inês; Ribeiro, Tânia; Machado, ManuelaIn this work, hydroethanolic plant extracts (acorn husk, laurel, eucalyptus, and rockrose leaves) were screened for their content in condensed tannins (HPLC-DAD/MS), polyphenol content, antioxidant, antimicrobial, and antiviral activities, and lack of toxicity. The results showed the highest values of condensed tannins found for laurel and eucalyptus extracts, while the total phenolic content ranged within 204....
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...
Evaluation of minimum inhibition concentrations of plant against environmental ...
Afonso, Tiago B.; Melo, Adma N.F.; Carvalho, Marta; Ribeiro, Tânia; Pinto, Miguel M.; Barros, Lillian; Carocho, Márcio; Tavaria, Freni K.The outbreak of COVID-19 disease eaused by SARS-CoV-2 has led the seientifie eompmnity to seareh for new alternatives to help eontrol the virus. In this context, the use of face masks has been reeommended as a preventive measure against the spread of SARS-CoV-2. The application of antimierobial agents in the tissues used to produee masks would be an additional hurdle on the prevention of other respiratory infee...
Plant extract with bioactive potential against SARS-CoV-2
Melo, Adma N.F.; Afonso, Tiago B.; Carvalho, Marta; Rodrigues, Cláudia; Ribeiro, Tânia; Carocho, Márcio; Pinto, Miguel M.; Tavaria, Freni K.The novel disease caused by SARS·CoV-2 has been causing chaos worldwide due to its high mortality, morbidity and contagiousness nature, and therefore forced the scientific world to develop n'ew alternatives to combat and assist the fight against this virus. Plant extracts have bioactive molecules that might provide a starting point for the research on the use of plants as an excellent source ofoew antiviral age...
