Extraction of phenolic compounds from Juglans regia L. leaves using aqueous sol...
Cordova, Isabella Weber; Oludemi, Taofiq; Vieira, Vanessa; Pires, Tânia C.S.P.; Pinho, Simão; Barros, Lillian; Ferreira, OlgaThe leaves of Juglans regia L. (walnut tree) are a rich source of bioactive phenolic compounds, particularly flavonoids and phenolic acids, which can be used in cosmetic applications due to their antioxidant properties. Conventionally, these compounds are extracted using volatile organic solvents. This study focuses on a more sustainable approach by designing a heat-assisted extraction process using aqueous sol...
Response surface methodology and artificial neural network modeling as predicti...
Silva, Ana Rita; Ayuso, Manuel; Oludemi, Taofiq; Gonçalves, Alexandre; Melgar Castañeda, Bruno; Barros, LillianThis study optimized the extraction of three major phenolic compounds (oleuropein, tyrosol, and verbascoside) from olive pomace using microwave- and ultrasonic-assisted methods. Screening factorial design (SFD) and central composite design (CCD) were employed, and response surface methodology (RSM) and artificial neural networks (ANN) were used for data modeling. The microwave-assisted method in the SFD yielded...
Untargeted metabolomics and in vitro functional analysis unravel the intraspeci...
Pereira, Antia Gonzalez; Cassani, Lucia; Oludemi, Taofiq; Chamorro, Franklin; Calhelha, Ricardo C.; Prieto Lage, Miguel A.; Barros, LillianThe Camellia genus comprises a vast array of underexplored medicinal plants that merit a systematic valorization to exploit their potential as natural sources of phytochemicals with associated health-promoting properties. In this work, flower extracts from eight poorly characterized Camellia japonica L. cultivars were subjected to polyphenol profiling through untargeted metabolomics combined with in vitro funct...
Recovery of high valuable bioactive molecules from Vaccinium myrtillus L. biore...
Plasencia, Paula; Heleno, Sandrina A.; Finimundy, Tiane C.; Carocho, Márcio; Calhelha, Ricardo C.; Añibarro-Ortega, Mikel; Alves, Maria JoséPurpose The interest in using bioresidues produced by the agri-food industry is increasingly intrinsic to the world economy. As such, researchers started to look for new ways to enhance its use, developing innovations to transform these residues into high-value raw materials with industrial application, promoting the circular economy concept. Methods Therefore, pruning residues from the production of Vaccinium ...
Pomeganate leaf extracts characterization and their potential use as a function...
Marcelino, Sandra Andreia; Mandim, Filipa; Oludemi, Taofiq; Heleno, Sandrina A.; Finimundy, Tiane C.; Prieto Lage, Miguel A.; Barros, LillianThe pomegranate tree (Punica granatum L.) is indigenous to the Mediterranean region and is one of the oldest known plants. Studies have demonstrated their many biological and pharmaceutical benefits, which have been correlated to their bioactive content, namely secondary metabolites such as phenolic compounds [1]. However, 40 to 50% of the whole fruit is discarded, such as peel and leaves, originating valuable ...
Genetic information influence on phenolic composition and bioactivities of Cera...
Marcelino, Sandra Andreia; Mandim, Filipa; Oludemi, Taofiq; Dias, Maria Inês; Barracosa, Paulo; Prieto Lage, Miguel A.; Barros, LillianCeratonia siliqua L., commonly known as the carob tree is native to the Mediterranean countries and is widely known and consumed. Due to its chemical constituents, flavoring properties, and nutritional benefits, it has the potential to be of significant importance to the food industry1. The carob bean is made up of 90% pulp and 10% seeds. Those seeds are widely used in the food industry as a thickening agent (E...
Comprehensive HPLC-DAD-(ESI-)MS/MS characterization and comparison of bioactive...
Rodrigues, Daniele Bobrowski; Oludemi, Taofiq; Petros, Peter; Barros, LillianGanoderma lucidum is a well-known medicinal mushroom, both historically and currently. Driven by the ethnopharmacological prospect and the crescent body of scientific evidence that associates G. lucidum intake with health, the interest in its secondary metabolites has been further fostered. Whereas most research on medicinal mushrooms has focused on the comprehensive identification and yields of metabolites thr...
Valorization of Juglans regia leaves as cosmeceutical ingredients: bioactivity ...
Besrour, Nermine; Oludemi, Taofiq; Mandim, Filipa; Pereira, Carla; Dias, Maria Inês; Soković, Marina; Stojković, Dejan; Ferreira, OlgaThe cosmetic industry is constantly searching for bioactive ingredients, namely, those obtained from natural sources with environmentally friendly connotations and less toxic effects. A previous study of our research group optimized the extraction of phenolic compounds from Juglans regia by heat-assisted extraction. Due to its richness in different phenolic compounds, the present work aimed to develop a formula...
How do extraction methodologies influence the biological properties of pomegran...
Marcelino, Sandra Andreia; Oludemi, Taofiq; Mandim, Filipa; Finimundy, Tiane C.; Prieto Lage, Miguel A.; Barros, LillianOne of the oldest known plants is the pomegranate tree (Punica granutum L.), native to the Mediterranean region. This plant's edible and non-edible portions have been shown to provide several health advantages. It has long been recognized as a source of bioactive chemicals, such as phenolic acids, flavonoids, tannins, alkaloids and amino acids. Large amounts of industrial waste are generated during the industri...
Characterization of in vitro antioxidant, antitumor and anti-inflammatory prope...
Garcia-Oliveira, Paula; Barral Martínez, Marta; Jarboui, Amira; Oludemi, Taofiq; García-Pérez, Pascual; Pinela, José; Mandim, FilipaSince ancient times, humans have employed different plant species to prepare traditional remedies and treat diseases, due to the health-promoting effects associated with these plants. Among them, several species belonging to the Rosaceae family, namely Agrimonia eupatoria L., Filipendula ulmaria (L.) Maxim. and Rosa canina L., which have been used in different preparations, like infusions, decoctions or tinctur...
