Barros, Diana; Alonso-Esteban, José Ignacio; Finimundy, Tiane C.; Pereira, Carla; Vaz, Josiana A.; Pereira-Pinto, Ricardo; Fernandes, ÉliaThis study conducted a comprehensive comparison of two green extraction methods, microwave-assisted extraction (MAE) and ultrasound-assisted extraction (UAE), for recovering bioactive phenolic compounds from Pinus pinaster bark. The goal was to valorize timber industry waste and enhance the value of by-products through the development of eco-friendly processes to extract phenolic compounds from Pinus pinaster A...
Exploring the Chemopreventive and Antioxidant Effects of Spearmint Leaf Hydroet...
Jesus, Tiago M.; Azevedo, Tiago; Silva-Reis, Rita; Ferreira, Tiago; Nascimento-Gonçalves, Elisabete; Medeiros, Catarina; Ferreira, João; Gama, AdelinaHuman papillomavirus (HPV) is the most common sexually transmitted infectious agent and, in cases of persistent infection, may cause cancer. This study evaluated the toxicological and antitumor properties of Mentha spicata extract (MSE) in KP14HPV16 mice, which carry HPV16 oncogenes. Thirty‑three female FVB/n mice (Mus musculus), including 17 HPV‑transgenic and 16 wild‑type (WT) mice, were divided into six grou...
Investigating bioactive compounds in apple pomace: Potential to develop high ad...
Pascoalino, Liege; Finimundy, Tiane C.; Pires, Tânia C.S.P.; Pereira, Carla; Barros, Lillian; Ferreira, Isabel C.F.R.; Oliveira, BeatrizThis study investigates bioactive compounds in apple pomace (AP) obtained from Malus domestica varieties Granny Smith and Cripps Pink, emphasizing its potential for developing high-added-value products from industrial surplus. Regarding its chemical characterization, AP stood out for its high concentration of dietary fibers (7.1g/100g fw), polyunsaturated fatty acids (linoleic and oleic acids), α-tocopherol (0....
Valorization of Waste from Bell Pepper: Chemical Composition and Bioactive Pote...
Baessa, Jozias; Liberal, Ângela; Finimundy, Tiane C.; Stojković, Dejan; Mišić, Danijela; Pires, Tânia C.S.P.; Barros, Lillian; Fernandes, ÂngelaAgri-food waste, especially in the fruit and vegetable sector, presents environmental and economic challenges. The bell pepper industry generates significant waste, offering potential for resource recovery within a circular economy. This study analyzed the nutritional and biochemical composition of waste from green, orange, and red bell peppers (Capsicum annuum L.) and evaluated the bioactive potential of hydro...

Pallarés, Noelia; Berrada, Houda; Ferrer, Emilia; Rached, Wahiba; Pinela, José; Mandim, Filipa; Pires, Tânia C.S.P.; Finimundy, Tiane C.Underutilized plant species such as Asteriscus graveolens (Forssk.) Less., Haloxylon scoparium Pomel, and Ruta chalepensis L. have been historically valued in traditional medicine for their potential health benefits. These species present an untapped source of bioactive compounds with significant applications in the food and pharmaceutical industries, including the development of functional foods and additives....
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...
