Ahmad, Samir M.; Calado, Bruno B.C.; Oliveira, Mariana N.; Neng, Nuno R.; Nogueira, J.M.F.In the present work we propose, for the first time, bar adsorptive microextraction coated with carbon-based phase mixtures, followed by microliquid desorption and high performance liquid chromatography-diode array detection (BAμE-μLD/HPLC-DAD) analysis, to enhance the performance of the determination of traces of benzotriazoles (BTRs), benzothiazoles (BTs), and benzenesulfonamide derivatives (BSDs) in environme...
Glycosyl flavonoids from Salvia sclareoides: contribution to the development of...
Abraços, L.; Martins, A.; Neng, N.; Nogueira, J.M.F.; Serralheiro, M.L.; Batista, A.P.; Raymundo, A.; Sousa, I.; Albuquerque, T.G.; Costa, H.S.Salvia sclareoides is a plant of spontaneous Portuguese vegetation that has relevant properties, as part of its cholinergic action and in the prevention of the formation of amyloid plaques. Previous studies suggested [1,2] that this species of Salvia can be used as a functional food and also in the development of a food supplement in the context of the prevention and treatment of Alzheimer's disease.

Aroma Profile Discrimination of Coffees and Industrial Blends According to the ...
Rodrigues, Carla Igreja; Máguas, Cristina; Nogueira, J.M.F.In the present work, static headspace solid phase microextraction using carboxen/polydimethylsiloxane polymeric fibre (HS-SPME(CAR/PDMS)) followed by gas chromatography-mass spectrometry (GC-MS), revealed the best analytical performance to characterize the aroma profile of coffees and industrial blends with different chromatic values (64.9, 70.6, 75.3, 86.1 and 89.6). The most relevant classes of aroma compound...
