Triacylglycerols profiling as a chemical tool to identify mushrooms submitted t...
Fernandes, Ângela; Barreira, João C.M.; Antonio, Amilcar L.; Martins, Anabela; Ferrreira, Isabel C.F.R.; Oliveira, M.B.P.P.In order to define irradiation treatment as a routine conservation methodology, it is imperative to develop chemometric indicators with the ability to distinguish irradiated from unirradiated foodstuffs. Electron spin resonance, photostimulated luminescence and thermoluminescence methods were employed to monitor radiation-induced markers, as well as different chemical compounds produced from the lipidic fractio...
Phytochemical characterization and antioxidant activity of Opuntia microdasys (...
Chahdoura, Hassiba; Barreira, João C.M.; Barros, Lillian; Santos-Buelga, Celestino; Ferrreira, Isabel C.F.R.; Achour, LotfiChemical composition and antioxidant activity of Opuntia microdasys flowers in different maturity stages was evaluated. Fructose, glucose, sucrose and trehalose were found; oxalic, quinic, malic, and citric acids were also detected; five hydroxycinnamoyl, two kaempferol and six isorhamnetin derivatives; 23 fatty acids were quantified in all stages, except C20:2, which was only found in post flowering stage (F3)...

Rashed, Khaled N.; Ćirić, Ana; Glamočlija, Jasmina; Calhelha, Ricardo C.; Ferrreira, Isabel C.F.R.; Soković, MarinaThis present investigation was undertaken to study antimicrobial and cytotoxic activities ofdichloromethane, ethyl acetate, and methanol 80% extracts from Alnus rugosa L. aerial parts, as wellinvestigate the bio-active compounds of each extract. Antimicrobial activity of the mentioned extractsagainst various bacteria and fungi using microdilution method, and cytotoxicity against five differenthuman tumor cell l...
Explorando a bioatividade dos cogumelos: propriedades antitumorais, antioxidant...
Ferrreira, Isabel C.F.R.Os cogumelos silvestres contêm uma enorme diversidade de biomoléculas com propriedades medicinais (Poucheret, Fons, & Rapior, 2006). Têm sido reconhecidos como al imentos funcionais e como uma fonte para o desenvolvimento de medicamentos e nutracêuticos. Os corpos de frutificação, o micélio e os esporos têm na sua constituição uma grande variedade de metabólitos bioativos com propriedades imunoestimu1adoras, ca...
