Sugarcane is an important agricultural crop in the economy of tropical regions, and Brazil has largest cultivated acreage world. accumulates high levels sucrose its stalks. Other compounds produced by sugarcane are currently not economic importance. To explore potential coproducts, we have studied chemical diversity genotypes, via metabolite profiling leaves NMR LC-DAD-MS. Metabolites were identified in-house public databases. From analysis 60 HPLC-fractionated extracts, LC-DAD-MS detected...
The application of computer-aided drug discovery (CADD) approaches has enabled the new antimicrobial therapeutic agents in past. high prevalence methicillin-resistantStaphylococcus aureus(MRSA) strains promoted this pathogen to a high-priority for development. In sense, modern CADD techniques can be valuable tools search agents. We employed combination series machine learning (ML) select and evaluate potential compounds with antibacterial activity against methicillin-susceptible S. aureus...
The anti-Mycobacterium tuberculosis activity of Campomanesia adamantium fruits extracts were evaluated. Six compounds, identified as flavanones and chalcones quantified by HPLC-DAD-UV. Promising antitubercular was observed with ethyl acetate extract (MIC 62.5 µg/mL) their fractions values ranging from 39 to above 250 µg/mL). better MIC result µg/mL associated two that contain bigger amounts 5,7-dihydroxy-6, 8-di-C-methylflavanone 2',4'-dihydroxy-3',5'-dimethyl-6'-methoxychalcone. These...
Exopolysaccharide (EPS) are produced by a diverse of rhizobia species and has been demonstrated to be bioemulsifier with potential applications in the degradation hydrocarbons. In present study, attempts were made obtain new exopolysaccharide production Rhizobium tropici (SEMIA 4080 MUTZC3) strains during growth on hydrocarbon substrate. Under different cultivation conditions, high molecular weight exopolysaccharides from cultivated for 96h mainly consisted carbohydrates (79-85%) low...
The essential oils from Campomanesia adamantium (Cambess.) O. Berg leaves, collected in the reproductive (flowering and fruit-bearing) vegetative stages, were characterized by GC-MS (Gas Chromatography-Mass Spectrometry). A total of 95 compounds identified. In stage (flowering) major constituents monoterpenes (limonene, α-pinene β-pinene) while during sesquiterpenes (bicyclogermacrene globulol). oil shows high antimicrobial activity against Staphylococcus aureus, Pseudomonas aeruginosa...
Campomanesia adamantium (Cambess.) O. Berg, Myrtaceae, é uma espécie nativa. As folhas são utilizadas na medicina popular. Os extratos hexânico e acetato de etila das mostraram pouca variação sua composição química em diferentes estações do ano associado com o desenvolvimento vegetal, enquanto extrato etanólico mostrou alteração significativa relação à química. Todos os etanólicos alta atividade antioxidante frente ao método DPPH moderada a para β-caroteno/ácido linoléico.
Metabolite profiling techniques play an important role in the phenotyping and diagnostic analysis of plants.
NMR and chromatography methods combined with mass spectrometry are the most important analytical techniques employed for plant metabolomics screening. Metabolomic analysis integrated to transcriptome screening add an extra dimension information flow from DNA RNA protein. The useful experiment in is proton spectra due high receptivity of 1H structural information, through proton–proton scalar coupling. Routinely, databases have been used identification primary metabolites, however, there...
Drought stress impacts soybean yields and physiological processes. However, the insertion of activated form AtAREB1 gene in cultivar BR16, which is sensitive to water deficit, improved drought response genetically modified plants. Thus, this study, we used 1H NMR solution solid-state investigate overexpressing under deficiency conditions. We achieved that drought-tolerant high content amino acids isoleucine, leucine, threonine, valine, proline, glutamate, aspartate, asparagine, tyrosine,...
Introduction Solid-state NMR (SSNMR) spectroscopy methods provide chemical environment and ultrastructural details that are not easily accessible by other non-destructive, high-resolution spectral techniques. High-resolution magic angle spinning (HR-MAS) has been widely used to obtain the metabolic profile of a heterogeneous sample, combining resolution enhancement provided MAS in SSNMR with shimming locking procedures liquid-state NMR. Objective In this work, we explored feasibility using...
Methanolic, diethyl ether and n-hexane extracts of leaves four species Senna (S. gardneri, S. macranthera, splendida trachypus) were analyzed by gas chromatography coupled to mass spectrometry (GC-MS).Using linear retention indices spectral data, 34 compounds identified, including fatty acids, flavonoids, terpenoids steroids that not reported previously for these species.Additionally, the cytotoxicity against different tumor cell lines was determined.The then correlated with chemical...
Abstract The essential oils obtained from the leaves and flowers Campomanesia adamantium (Myrtaceae) collected in Mato Grosso do Sul flowering stage were analyzed by GC GC/MS. Eighty-two components identified leaf oil thirty-seven flower oil. constituent major was limonene (21.9%) ledol (20.9%)
The BW has been largely used as a selection criterion in genetic programmes; however, increases can affect animal metabolism and metabolites. knowledge of how potential for growth affects the metabolites give footprint metabolism. This research aimed to evaluate effect post-weaning (GG) on performance, carcass traits serum metabolome non-castrated Nellore males during finishing phase. Forty-eight males, with divergent growth, were selected divided into two groups: high (HG; n = 24) low (LG;...
Objective: To guide health education about syphilis through TikTok digital media, addressing the forms of contamination, signs and symptoms, diagnosis, prevention treatment. Methods: The method used for development this project was Arco de Maguerez, which consists five stages that are observation reality, key points, theorizing, solution hypothesis application reality. Experience report: Social media currently excellent tools dissemination information, because it is possible to create,...
Com base no conceito de economia circular, resíduos fontes vegetais, entre eles manga, são reaproveitados e podem ser extraídas algumas biomoléculas como pectina celulose para serem utilizadas em aplicações biotecnológicas, também a indústria cosmética, até mesmo biomateriais. Neste contexto, foi realizada caracterização térmica, morfológica reológica biopolímeros puros misturas gel analisar seu potencial produzir membranas, scaffolds ou estruturas bioimpressas. A análise FTIR demonstrando...
Cariniana estrellensis (Raddi) Kuntze seedlings have been used in forest restoration programs the Atlantic Forest biome. However, despite economic and ecological relevance of this species, to date no general method for rapid identification primary secondary metabolites C. leaves has reported. In work, we explore feasibility using analysis by nuclear magnetic resonance techniques liquid chromatography coupled diode array, charged aerosol, mass detection. The main identified were hydrolysable...
Abstract Drought stress impacts soybean yield and physiological processes. However, the insertion of activated form AtAREB1 gene in cultivar BR16, which is sensitive to water deficit improved drought response genetically-modified plants under glasshouse conditions. Thus, this study used 1 H NMR solution solid-state investigate genetically modified overexpressing AREB deficiency We achieved that drought-tolerant yields high content amino acids isoleucine, leucine, threonine, valine, proline,...
