“…The analysis was performed using a LC-DAD-ESI/MSn (Dionex Ultimate 3000 UPLC, Thermo Scientific, San Jose, CA, USA) as previously described by Bessada, Barreira, Barros, Ferreira, and Oliveira (2016). Double online detection was performed using 280, 330 and 370 nm as preferred wavelengths for DAD and in a mass spectrometer (MS).…”

A B S T R A C TThe edible flowers are widely used, but there is still a lot to be done in relation to its bioactive potential and its correlation with the presence of phenolic compounds. The aim of this study was determined the individual phenolic profile in the hydromethanolic extracts and infusion preparations of four different flower samples (Dahlia mignon, Rosa damascena 'Alexandria' and R. gallica 'Francesa' draft in R. canina, Calendula officinalis L., and Centaurea cyanus L.) and their bioactive potential (antioxidant, antiproliferative, and antibacterial capacity). All the studied flowers presented different profiles regarding their phenolic composition and revealed biological potential. The bioactive potential of the studied flowers was moderate, the hydromethanolic extracts of rose petals showed the best results for antioxidant and antibacterial assays, while the antiproliferative properties were only present in some of the tested cell lines, for the hydromethanolic extracts, in which dahlia and rose showed the best results. These results demonstrate that edible flowers can be used as a source of phenolic compounds with bioactive potential, which can be applied in the food sector, as foods and as sources natural ingredients.

“…The lyophilized extracts were re-dissolved in a 80:20 methanol:-water (v/v mixture and the phenolic profile was determined by highperformance liquid chromatography-diode array detection-electrospray ionization multi-stage mass spectrometry (HPLC-DAD-ESI)/MSn (Dionex Ultimate 3000 UPLC, Thermo Scientific, San Jose, CA, USA) as previously described by Bessada, Barreira, Barros, Ferreira, & Oliveira (2016). Double online detection was carried by DAD using 280 and 370 nm as the preferred wavelengths and a mass spectrometer connected to the HPLC system via the DAD cell outlet.…”

A B S T R A C TSeeds from Araucaria angustifolia (Bertol.) Kuntze are consumed after cooking and their coats discarded. Both coats and the cooking water present phenolic compounds, which may be used to improve mechanical properties and provide antioxidant characteristics to films. The objective of this work was to obtain and pinhão coat extracts and to apply these polyphenolic-rich extracts in zein films. Phenolic compounds composition, extraction yield and antioxidant activity (DPPH, ABTS and FRAP) of the extracts were determined. The most abundant molecules present in the hydroethanolic extract were (+)-catechin and an (epi)catechin dimer, whereas protocatechuic acid were predominant in the both cooking water and ethanolic extracts. Glass transition temperature of zein was not found in the extract-loaded films. Morphological changes were also caused by the presence of the extracts yielding smoother surfaces. The extracts added to zein films led to a three-fold increase in tensile strength (from 5.80 MPa to 17.65 MPa) and two-fold increase in the elongation at break (from 1.60% to 3.18%).

“…The gradient elution applied was: 15% B (0e5 min), 15% B to 20% B (5e10 min), 20e25% B (10e20 min), 25e35% B (20e30 min), 35e50% B (30e40 min), the column was then re-equilibrated, using a flow rate of 0.5 mL/min. Data was collected simultaneously with DAD (280 nm) and in negative mode detection on a Linear Ion Trap LTQ XL mass spectrometer (ThermoScientific, San Jose, CA, USA), following a procedure previously described by Bessada et al (2016). Xcalibur ® data system (ThermoScientific, San Jose, CA, USA) was used in data acquisition.…”

a b s t r a c tGanoderma lucidum was characterized in terms of nutritional value and chemical composition. Thereafter, ethanolic Soxhlet extracts were evaluated for antioxidant, anti-inflammatory, antityrosinase, antimicrobial and cytotoxic effects, and further characterized in terms of phenolic acids, polysaccharides and triterpenoids. Finally, the obtained extracts were tested as cosmeceutical ingredients. G. lucidum proved to be a source of macronutrients and important bioactive compounds such as terpenoids, specially triterpenoids, and polysaccharides. In the extracts, ganoderic acids C2, A and H were the most abundant triterpenic acids and protocatechuic, p-hydroxibenzoic and syringic acids the identified phenolics. The developed cosmeceutical formulation preserved the extract bioactivities, presented a lightyellow colour and a pH of 4.6, which is considered appropriate for cosmeceutical's design. Behind the important nutritional/bioactive composition of G. lucidum, a potential towards its valorisation in the field of cosmeceuticals is foreseeable, as deduced from the bioactivities of its ethanolic extract and preservation in the tested formulation.
