This study aimed to quantify the levels of resveratrol, coumarin, and other bioactives in pulps by-products twelve tropical fruits from Brazil obtained during pulp production process. Pineapple, acerola, monbin, cashew apple, guava, soursop, papaya, mango, passion fruit, surinam cherry, sapodilla, tamarind were evaluated as well their (peel, pulp's leftovers, seed). Total phenolic, anthocyanins, yellow flavonoids, β-carotene lycopene also determined. Resveratrol was identified guava cherry...
Hydrogels have been prepared by free-radical solution copolymerization of acrylamide and sodium acrylate (NaAc), with molar ratio ranging from 25/75 to 80/20, respectively, using methylene bisacrylamide as the crosslinking agent. A FTIR spectroscopy procedure determine acrylate/acrylamide in these hydrogels was proposed based on absorbance at 1410 cm-1 (nCOO-) 2940 (nCH nCH2). straight line a good linear correlation coefficient (0.998) obtained plotting content (Ac%) versus relative (Arel =...
Abstract Background Lentinula edodes , known as shiitake, has been utilized food, well as, in popular medicine, moreover, compounds isolated from its mycelium and fruiting body have shown several therapeutic properties. The aim of this study was to determine the antiviral activity aqueous (AqE) ethanol (EtOHE) extracts polysaccharide (LeP) replication poliovirus type 1 (PV-1) bovine herpes virus (BoHV-1). Methods time-of-addition assay performed at times -2, -1, 0, 2 h infection. virucidal...
The micellization in dilute aqueous solution of Pluronic copolymers P123 (E21P67E21) and F127 (E98P67E98) mixtures the two was investigated using static dynamic light scattering. Gelation concentrated solutions their studied tube inversion oscillatory rheometry. comicellized to give micelles with narrow size distributions. Clouding temperatures critical micelle decreased as proportion mixture increased. Micelle association numbers mixed lay between values found for alone, whereas radii...
Chitosan-based magnetite nanocomposites were synthesized using a versatile ultrasound assisted in situ method involving one quick step. This synthetic route approach results the formation of spheroidal nanoparticles (Fe3O4) with average diameter between 10 and 24nm, which found to be superparamagnetic saturation magnetization (Ms) ranges from 32-57emug(-1), depending on concentration. The incorporation Fe3O4 into chitosan matrix was also confirmed by FTIR TG techniques. hybrid nanocomposite...
In this work, chitosan/magnetite nanoparticles (ChM) were quickly synthesized according to our previous report based on co-precipitation reaction under ultrasound (US) irradiation. Besides ChM was in-depth structurally characterized, showing a crystalline phase corresponding magnetite and presenting spheric morphology, “nanorod”-type morphology also obtained after increasing time for eight minutes. Successfully, both morphologies presented nanoscale range with an average particle size of...
Intestinal mucositis, characterized by inflammatory and/or ulcerative processes in the gastrointestinal tract, occurs due to cellular and tissue damage following treatment with 5-fluorouracil (5-FU). Rutin (RUT), a natural flavonoid extracted from Dimorphandra gardneriana, exhibits antioxidant, anti-inflammatory, cytoprotective, gastroprotective properties. However, effect of RUT on intestine, especially mucositis promoted antineoplastic agents, has not yet been reported. In this study, we...
CNSL is a mixture of meta-alkylphenols with variable degree unsaturation attached to the benzene ring. The kinetic study thermal degradation at 140 °C synthetic cis-1,4-polyisoprene film, in presence technical and some derivatives (cardanol, hydrogenated cardanol alkylated cardanol) was carried out by FTIR. amount OH/OOH C=O formed also C=C consumed during determined. All materials increase induction period decrease apparent rate constants thermal-oxidation. Based on parameters, order...
The antimicrobial, antioxidant, and anticholinesterase activities of ethanolic seed extracts twenty-one plant species from Brazilian semiarid region were investigated. tested for antimicrobial activity against six bacteria strains three yeasts. Six presented the Gram (-) organism Salmonella choleraesuis (+) organisms Staphylococcus aureus Bacillus subtilis. MIC values ranged 4.96 to 37.32 mg/mL. Triplaris gardneriana extract species, with 18.8, 13.76, 11.15 mg/mL, respectively. Five...
Herpes simplex virus (HSV) is one of the most regular human pathogens, being a public health problem, and causal agent several diseases. Poliovirus (PV) an enteric about 1% infected individuals develop paralytic poliomyelitis due to viral invasion central nervous system destruction motor neurons. This work evaluated activity sulfated polysaccharide Caesalpinia ferrea (SPLCf) in HSV PV replication. The antiviral effect SPLCf at varying concentrations was tested by plaque assay under...
