Plant cell cultures of Nordic berry species: Phenolic and carotenoid profiling ...
Rischer, Heiko; Nohynek, Liisa; Puupponen-Pimiä, Riitta; Aguiar, Joselin; Rocchetti, Gabriele; Lucini, Luigi; Câmara, José S.; Mendanha Cruz, ThiagoPlant cell cultures from cloudberry (CL), lingonberry (LI), stone berry (ST), arctic bramble (AB), and strawberry (SB) were studied in terms of their polyphenol and carotenoid composition, antioxidant activity, antihemolytic activity and cytotoxicity effects on cancerous cells. High-resolution mass spectrometry data showed that LI, presented the highest antioxidant activity, contained the highest contents of fl...
Structure assignment of seized products containing cathinone derivatives using ...
Gonçalves, João; Alves, Vera; Aguiar, Joselin; Caldeira, Maria J.; Teixeira, Helena M.; Câmara, José S.The innovation of the new psychoactive substances (NPS) market requires the rapid identification of new substances that can be a risk to public health, in order to reduce the damage from their use. Twelve seized products suspected to contain illicit substances were analyzed by attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), gas chromatography coupled to mass spectrometry (GC-MS)...
Food bioactive compounds and emerging techniques for their extraction: Polyphen...
Câmara, José S.; Albuquerque, Bianca R.; Aguiar, Joselin; Corrêa, Rúbia C.G.; Gonçalves, João L.; Granato, Daniel; Pereira, Jorge A.M.; Barros, LillianExperimental studies have provided convincing evidence that food bioactive compounds (FBCs) have a positive biological impact on human health, exerting protective effects against noncommunicable diseases (NCD) including cancer and cardiovascular (CVDs), metabolic, and neurodegenerative disorders (NDDs). These benefits have been associated with the presence of secondary metabolites, namely polyphenols, glucosino...

Relationship between Volatile Composition and Bioactive Potential of Vegetables...
Aguiar, Joselin; Gonçalves, João L.; Alves, Vera L.; Câmara, José S.In recent years, there has been a growing interest in studying and exploring the potential health benefits of foods, mainly from vegetables and fruits from regular intake. The presence of secondary metabolites, namely polyphenols, carotenoids and terpenes, in certain food matrices seems to contribute to their functional properties, expressed through an increased prevention in the development of certain chronic ...

Chemical fingerprint of free polyphenols and antioxidant activity in dietary fr...
Aguiar, Joselin; Gonçalves, João L.; Alves, Vera L.; Câmara, José S.Fruits and vegetables are considered a good source of antioxidants, which are beneficial in protecting the human body against damage induced by free radicals and other reactive oxygen (ROS) and nitrogen (RNS) species. In this work, we aimed to evaluate the integral antioxidant activity (AOA) and determine individual polyphenols in fruits and vegetables of frequent consumption. For this purpose, an innovative an...
The synthetic cannabinoids phenomenon: from structure to toxicological properti...
Alves, Vera L.; Gonçalves, João L.; Aguiar, Joselin; Teixeira, Helena M.; Câmara, José S.The word “cannabinoid” refers to every chemical substance, regardless of structure or origin, that joins the cannabinoid receptors of the body and brain and that have similar effects to those produced by the Cannabis plant and based on their source of production, cannabinoids can be classified into endocannabinoids, phytocannabinoids and synthetic cannabinoids. Synthetic cannabinoids represent the largest class...
