Mushrooms 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...

Cavichi, Lucas V.; Liberal, Ângela; Dias, Maria Inês; Mandim, Filipa; Pinela, José; Kostić, Marina; Soković, Marina; Kalschne, Daneysa Lahis

In recent years, the interest in products of natural origin has boosted the exploitation and use of plants as food and sources of bioactive compounds, especially wild plants widely used in different cultures for several purposes. Commelina erecta is a wild edible plant (WEP) traditionally used as food and medicine, about which few studies exist. Thus, this study aimed at enhancing the knowledge about its nutrit...

Pereira, Alexis; Añibarro-Ortega, Mikel; Kostić, Marina; Nogueira, António José M.; Soković, Marina; Pinela, José; Barros, Lillian

This study aimed to promote the total upcycling of quince (Cydonia oblonga Mill.) peel into bioactive extracts (BEs) and fiber concentrates (FCs). The multicomponent extraction processes were optimized using response surface methodology (RSM) coupled with a 20-run experimental design, where the effects of time (1-120 min), temperature (25-95 degrees C), and EtOH percentage (0-100%) were combined. In addition to...

Phytochemical composition and bioactive potential of melissa officinalis L., Sa...

Silva, Beatriz Nunes; Cadavez, Vasco; Caleja, Cristina; Pereira, Eliana; Calhelha, Ricardo C.; Añibarro-Ortega, Mikel; Finimundy, Tiane C.

Plants are rich in bioactive phytochemicals that often display medicinal properties. These can play an important role in the production of health-promoting food additives and the replacement of artificial ones. In this sense, this study aimed to characterise the polyphenolic profile and bioactive properties of the decoctions, infusions and hydroethanolic extracts of three plants: lemon balm (Melissa officinalis...

Chemical composition and biological activity of cardoon (Cynara cardunculus L. ...

Mandim, Filipa; Petropoulos, Spyridon Α.; Pinela, José; Dias, Maria Inês; Giannoulis, Kyriakos D.; Kostić, Marina; Soković, Marina; Queijo, Beatriz

Cardoon seeds collected in Greece at four different maturity stages (samples S1 to S4) were analysed in terms of chemical composition and in vitro bioactivities. The content of phenolic compounds (six compounds in total) increased with increasing maturity, and 3,5-O-dicaffeyolquinic (14.8–33.8 mg/g extract) acid was the compound detected in higher abundance. Mature seeds (sample S4) also revealed the highest co...

Characterization of the biological residue Brassica oleracea L. to obtain a pot...

Pepinelli, Ana Luísa; Oliveira, Tatiane C.G.; Caleja, Cristina; Dias, Maria Inês; Kostić, Marina; Soković, Marina; Gonçalves, Odinei Hess

The food industry has been looking for natural matrices with potential application as natural ingredients. In this sense, the aim of this work was to characterize the Brassica oleracea var. Acephala biowastes, popularly known as kale, regarding its individual phenolic profile and biological action, in order to identify phenolic compounds with preservative and/or bioactive potential for incorporation in the food...

Water stress alleviation effects of biostimulants on greenhouse-grown tomato fruit

Fernandes, Ângela; Chaski, Christina; Pereira, Carla; Kostić, Marina; Rouphael, Youssef; Soković, Marina; Barros, Lillian

The aim of the present study was to evaluate the effects of three biostimulant products (Nomoren (N), Twin Antistress (TW), x-Stress (XS) and control treatment (C: no biostimulants added)) on the nutritional value, chemical composition and bioactive properties of greenhouse tomato fruit grown under full (W+: 100% of field capacity) and deficit irrigation (W–: 70% of field capacity) conditions. Fat content was t...

Evaluation of parasite and host phenolic composition and bioactivities − The pr...

Silva, Ana Rita; Ayuso, Manuel; Pereira, Carla; Dias, Maria Inês; Kostić, Marina; Calhelha, Ricardo C.; Soković, Marina; García, Pablo A.

Cytinus hypocistis (L.) L. is a comestible holoparasite with great potential for cosmeceutical application. Although its high tannin content has been associated with its bioactive and inhibitory enzyme properties, this is the first report establishing a relationship between parasite and host (Halimium lasianthum (Lam.) Greuter) phenolic profile and bioactive properties. Thus, five extracts (aerial and root extr...

Pires Junior, Eleomar de O.; Pereira, Eliana; Pereira, Carla; Dias, Maria Inês; Calhelha, Ricardo C.; Kostić, Marina; Soković, Marina

Ocimum basilicum 'Cinnamon' is an aromatic and medicinal herb belonging to the Lamiaceae family [1]. Cinnamon basil, as it is popularly known, has aroused the interest of the scientific community for presenting significant concentrations of phenolic compounds [2]. Due to the increasing concern that consumers have towards artificial additives, an intensification in the demand for safer and natural preservatives ...
