Authenticity and Bioactive Markers Search in the Phenolic‐Rich Extracts of Aste...
Garcia Perez, Pascual; Garcia‐Oliveira, Paula; Finimundy, Tiane C.; Pinela, José; Calhelha, Ricardo C.; Nenadić, Marija; Soković, MarinaThe Asteraceae family has been of significant concern for ethnobotanical studies, thanks to its health-promoting properties linked to a plethora of bioactive compounds, among which phenolic compounds play a critical role. In this work, a workflow based on computational chemometrics was employed to assess the authenticity and biomarker search of five key Asteraceae species commonly employed in traditional medici...
Nutrients, Phytochemicals, and In Vitro Biological Activities of Goldenberry (P...
Añibarro-Ortega, Mikel; Dias, Maria Inês; Petrović, Jovana; Mandim, Filipa; Núñez, Sonia; Soković, Marina; López, Víctor; Barros, Lillian; Pinela, JoséThis study provides a comprehensive characterization of Physalis peruviana L., covering the nutritional composition of the fruit and the phytochemical profiles and in vitro bioactive properties of berry and calyx extracts. The fresh fruit stood out as a source of dietary fiber (5.16 g/100 g) and is low in fat (0.49 g/100 g). A 100-g serving also contained notable amounts of ascorbic acid (32.0 mg), tocopherols ...
Valorization of Solanum melongena L. crop by-products: phenolic composition and...
Añibarro-Ortega, Mikel; Dias, Maria Inês; Petrović, Jovana; Núñez, Sonia; Calhelha, Ricardo C.; Costa, Eduardo M.; Machado, M.; Pintado, ManuelaThis study explored the valorization of post-harvest eggplant aerial parts as a sustainable source of value-added ingredients by investigating their phenolic composition and in vitro bioactive properties. HPLC-DAD-ESI/MSn analysis identified chlorogenic acid derivatives as the predominant phenolic compounds (53 % of the phenolic fraction), followed by O-glycosylated kaempferol and quercetin. The extract display...

Añibarro-Ortega, Mikel; Dias, Maria Inês; Petrović, Jovana; Pereira, Alexis; Soković, Marina; Barros, Lillian; Pinela, JoséLulo or naranjilla (Solanum quitoense Lam.) is an Andean fruit with a sour and refreshing flavor, widely used in the preparation of juices and sweets. Despite its potential for international markets, it remains largely unknown outside its native regions, and most existing studies have focused on the whole fruit or its juice. This study investigated the nutritional and phenolic profiles of the peel, pulp, and se...
Chemical profiles and bioactivities of polyphenolic extracts of Lavandula stoec...
Silva, Beatriz Nunes; Cadavez, Vasco; Caleja, Cristina; Pereira, Eliana; Calhelha, Ricardo C.; Molina, Adriana K.; Finimundy, Tiane C.; Kostić, MarinaThis study assessed the chemical profiles and bioactivities of the infusions, decoctions and hydroethanolic extracts of tarragon, basil and French lavender. The extracts were chemically characterised (HPLC-DAD-ESI/MS) and their bioactivities were evaluated in vitro. All extracts revealed antimicrobial, antifungal and antioxidant properties. French lavender extracts showed higher total phenolic content, regardle...
Insights into the phenolic composition and in vitro bioactivity of cardoon capi...
Mandim, Filipa; Pinela, José; Marcelino, Sandra Andreia; Dias, Maria Inês; Barracosa, Paulo; Ivanov, Marija; Soković, Marina; Santos-Buelga, CelestinoThe capitulum constituents (stigma, corolla, bracts, pappus, and receptacle) of seven cardoon cultivars were studied for their polyphenolic composition and bioactive properties. Fifteen phenolic compounds were identified, secoiridoid, secoxyloganin, and apigenin-O-hexuronoside in higher concentrations. The bracts had the highest concentration of phenolic compounds, and the corolla had the greatest variety. The ...
Bioactives of the essential oil from the leaves of Eugenia pyriformis Cambess (...
Medeiros, Jaqueline Pavelegini de; Rodrigues, Selma Alves; Sakumoto, Karina; Ruiz, Suelen Pereira; Faria, Maria Graciela Iecher; Gonçalves, José EduardoLung cancer is the most commonly diagnosed and the main cause of cancer death, usually related to cigarette smoking. Furthermore, the microbiota of people exposed to cigarette smoke can be modified, making it difficult to eliminate opportunistic microorganisms. The leaves of Eugenia pyriformis are a by-product of fruit production and, to date, there have been no studies addressing the antiproliferative, anti-in...
Phenolic composition and in vitro bioactive and enzyme inhibitory properties of...
Añibarro-Ortega, Mikel; López, Víctor; Núñez, Sonia; Petrović, Jovana; Mandim, Filipa; Barros, Lillian; Soković, Marina; Ferreira, Isabel C.F.R.The phenolic composition and bioactive properties of Holland and Italian bell pepper plant (Capsicum annuum L.) hydroethanolic extracts were investigated by HPLC-DAD-ESI/MS and in vitro cell- and enzyme-based assays, respectively. O-Glycosylated luteolin derivatives were identified as the major compounds, representing -60% of the phenolic fraction. Both extracts displayed remarkable antioxidant activity and abi...
Biochemical Composition of Pumpkin Seeds and Seed By-Products
Polyzos, Nikolaos; Fernandes, Ângela; Calhelha, Ricardo C.; Petrović, Jovana; Soković, Marina; Ferreira, Isabel C.F.R.; Barros, LillianThe goal of the current work was to assess the nutritional profile and phytochemical properties of cucurbit (Cucurbita maxima L.) seeds, seed oils and oil extraction by-products (e.g., seed-cakes). Our results suggest a high nutritional value for both cucurbit seeds and cucurbit cake, while γ-tocopherol was the richest compound, with traces of α, β and δ-tocopherol compounds also detected. Regarding the free su...
