1. Development and Chemical Characterization of Pequi Pericarp Flour (Caryocar brasiliense Camb.) and Effect of in vitro Digestibility on the Bioaccessibility of Phenolic Compounds
The pequi pericarp corresponds to the largest portion of the fruit and has a high nutritional value, but it is discarded as an agro-industrial residue. The present study aimed to prepare and characterize flours from the pequi pericarp in terms of their proximate composition, its antioxidant potential before and after the in vitro digestibility process and ch

2. Use of Paper Spray Mass Spectrometry for Determining the Chemical Profile of Green Cavendish Banana (Musa AAA) Peel and Pulp Flours and Evaluation of Its Functional Potential
Green Cavendish banana peel and pulp flours were obtained by three drying methods: oven dryer at 70 °C; air fryer at 180 °C and domestic oven at 180 °C, being the latter two new possibilities. Bioactive constituents using paper spray ionization mass spectrometry (PS-MS), phenolic identification and quantification by ultra-performance liquid chromatography

3. Spontaneous vegetative propagules differentiation in Bowdichia virgilioides seedlings maintained at MS basal medium
ABSTRACT Bowdichia virgilioides Kunth is a medium size tree used in folk medicine and in furniture manufacturing which makes it a target of extractive processes. The aim of this work was to evaluate the endogenous content of polyamines, amino acids, and sugars in seedlings of Bowdichia virgilioides that presented or not the development of spontaneously diffe

4. Avanços recentes na química dos aminoaçúcares: ocorrência, biossíntese, síntese e aplicação
Amino sugars are chemical compounds that have a sugar backbone, in which one of the hydroxyl groups is replaced by an amino group. Derivatives of amine-containing sugars, such as N-acetylglucosamine, are also considered amino sugars. The synthetic introduction of amino functionalities in a regio- and stereoselective manner ontosugar scaffolds represents a su

6. Germination and biochemical changes in West Indian gherkin seeds under water stress at different temperatures
RESUMO As informações sobre os efeitos das condições climáticas na sobrevivência de espécies cultivadas em regiões semiáridas são imprescindíveis e, ainda, escassas, principalmente em se tratando de espécies rústicas como o maxixe (Cucumis anguria L.). Com isso, objetivou-se avaliar a germinação, crescimento e alterações bioquímicas em seme

7. Antioxidant Activity and Metabolomic Analysis of Cagaitas (Eugenia dysenterica) using Paper Spray Mass Spectrometry
Cagaita is a fruit from Brazilian cerrado, belongs to Myrtaceae family, and has important economic value. This work aimed to determine the total antioxidant capacity (extractable and non-extractable fractions) by different methods and to evaluate the use of paper spray mass spectrometry to obtain fingerprints of cagaita from different regions with the aid of

8. Analysis of Isomeric Cannabinoid Standards and Cannabis Products by UPLC-ESI-TWIM-MS: a Comparison with GC-MS and GC × GC-QMS
The Cannabis sativa L. plant has a complex chemical composition, containing various chemical compounds such as terpenes, sugars, hydrocarbons, steroids, flavonoids, and amino acids. Few works have attempted to identify the constitutional isomers of cannabinoids that are found in the plant. The present study reported the analysis of seven cannabinoid standard

9. Contribution of dark septate fungi to the nutrient uptake and growth of rice plants
ABSTRACT The use of dark septate fungi (DSE) to promote plant growth can be beneficial to agriculture, and these organisms are important allies in the search for sustainable agriculture practices. This study investigates the contribution of dark septate fungi to the absorption of nutrients by rice plants and their ensuing growth. Four dark septate fungi isol

10. GC–MS based metabolite profiling and angiotensin I-converting enzyme inhibitory property of black tea extracts
Abstract Angiotensin I-converting enzyme inhibitors are used as therapeutic agents for the treatment of hypertension. Regular consumption of black tea (Camellia sinensis (L.) Kuntze, Theaceae) has been reported to lower blood pressure. The aims of the present work were to compare chemical composition and angiotensin I-converting enzyme inhibitory properties

11. Metabolic profile and β-glucuronidase inhibitory property of three species of Swertia
ABSTRACT β-Glucuronidase inhibitors are suggested as potential hepatoprotective agents. Swertia chirayita (Roxb.) Buch.-Ham. ex C.B. Clarke, Gentianaceae, is known for its hepatoprotective and anti-hepatotoxic activity in Ayurvedic system of medicine for ages. This plant is substituted by other species like S. decussata Nimmo ex C.B. Clarke and S. bimaculat

12. A DETERMINAÇÃO DOS PRODUTOS AVANÇADOS DE GLICAÇÃO (AGES) E DE LIPOXIDAÇÃO (ALES) EM ALIMENTOS E EM SISTEMAS BIOLÓGICOS: AVANÇOS, DESAFIOS E PERSPECTIVAS
Advanced glycation (AGEs) and lipoxidation (ALEs) products are formed through specific condensation reactions between nucleophiles (amino groups of free amino acids or their residues in peptides, aminophospholipids or proteins) and electrophiles (carbonyls of reducing sugars, oxidized lipids or others) generating well-defined sets of covalent adducts. The ε
