Neves, Andréa Maria; Morais, Selene Maia de; Santos, Hélcio Silva dos; Ferreira, Marcílio Matos; Cruz, Ricardo Carneiro Vera; Souza, Elnatan Bezerra deThe objective of this work was to evaluate the chemical profile, total phenol content and the antioxidant, antiacetylcholinesterase and antifungal activities of ethanol extracts from leaves (EEF) and stem (EEC) of five species of Senna, as well as to evaluate the correlation between the content of total phenols with the DPPH free radical scavenging activity and with the inhibition of the acetylcholinesterase AC...
Brazilian plants with anticholinesterase action – a review
Lopes, Francisco Flávio da Silva; Frota, Lucas Soares; Fontenele, Gilson Araújo; Silva, Marcus Vinícius Ferreira da; Fernandes, Victor BorgesBrazil has a large flora distributed throughout its territory, containing the greatest genetic diversity in species in the world, many of them used for therapeutic purposes. Plants are the best sources for discovering bioactive compounds against diseases. Alzheimer's Disease is a neurodegenerative disease characterized by memory loss, mainly affecting the population over 65 years of age. This work describes a s...
Curcumins and its derivatives as potential inhibitors of New Coronavirus (COVID...
Alves, Daniela Ribeiro; Rocha, Matheus Nunes da; Passos, Camila Caldas Oliveira; Marinho, Márcia Machado; Marinho, Emmanuel SilvaCoronavirus (COVID-19) disease outbreak caused a worldwide pandemic with a powerful lethal potential and still, there is no specific treatment to it. Natural bioactive molecules like curcumins were investigated in this work aiming to block the active site of COVID-19 Main protease (Mpro), since they present several biological activities, being more suitable in terms of fewer side effects, once this disease over...
Cuticular hydrocarbons from ants (Hymenoptera: Formicidae) Odontomachus bauri (...
Azevedo Filho, Paulo Aragão de; Vasconcelos, Fábio Roger; Santos, Rayanne Castro Gomes dos; Morais, Selene Maia deSemiochemicals, 5-methyl-nonacosane, Alkanes, Chromatography.Ants are eusocial organisms with great relative abundance and species richness. Studies on these organisms are scarce, especially in the high altitude humid forest environments of the state of Ceará. In view of this condition, an evaluation of the chemical composition of cuticular hydrocarbons (CHCs) of the species Odontomachus bauri found and recorde...
Dyes and pigments used in foods: an integrative literature review
Oliveira, Micael Estevão Pereira de; Silva , Wildson Max Barbosa da; Alves, Daniela Ribeiro; Andrade Neto, João Batista de; Morais, Selene Maia deThe food colors are, in many countries, widely used to give food increased visual sensory quality, aiming, thus, the growth of the consumer market. Aware of this, the present work aimed to reevaluate the general properties of synthetic food dyes and natural pigments, the latter being generally used to replace the former. Then, the current analysis was based on the search for the strategy, selection of articles ...

Frota, Lucas Soares; Lopes, Francisco Flavio Sousa; Alves , Daniela Ribeiro; Freitas, Leonardo Soares; Franco, Gabriela Marinho GonçalvesThe medicinal plant Ouratea fieldinfiana popularly known as batiputá, is commonly found in the coastal region of Ceará, belonging to the Ochnaceae family and with arboreal or shrubby characteristics, an oil can be extracted from its fruit that is used in cooking and in traditional medicine as an anti-inflammatory. This work aimed to characterize the batiputá oil and the polar fraction of this oil, as well as to...
Influence of climatic variables on the epidemiological situation of dengue in t...
Morais, Selene Maia de; Farias, Silvana Silveira deDengue is a worldwide public health problem; studies show a correlation between dengue and climatic variables. Thus, this research aimed to investigate the correlation of the number of cases of patients with primary dengue symptoms (NCPPDS) with the compensated average temperature (TCA), average precipitation (PA) and compensated average relative humidity (RHCA) for the state of Ceará (2013-2018), in addition t...

Nutritional ranking of 30 Brazilian genotypes of cowpeas including determinatio...
Carvalho, Ana Fontenele Urano; Sousa, Nathanna Mateus de; Farias, Davi Felipe; Rocha-Bezerra, Lady Clarissa Brito da; Silva, Renata Maria Pereira daThis study aimed to establish a nutritional ranking of 30 genotypes of cowpea (Vigna unguiculata L. Walp). The results showed the proximate composition varies among genotypes in protein (20–30%) and dietary fiber contents (20–35%), in protease inhibitors (2–4 UI/mg protein), lectin (40,000–640,000 UH/kg meal) and essential amino acid levels, in vitro protein digestibility (30–40%) and in the apparent concentrat...
