The present study aimed at characterizing the oil extracted from Bertholletia excelsa H.B.K. almond, a native species Amazon region. Analytical methods used for oils and fats were employed through pharmacopoeia assays, AOCS (American Oil Chemists Society) standard as well those recommended by ANVISA (National Health Surveillance Agency) such acidity, peroxide value, saponification index, iodine value refractive pH relative density, also thermoanalytical analyses (thermogravimetry,...
The development of inclusion complexes is used to encapsulate nonpolar compounds and improve their physicochemical characteristics. This study aims develop made up Euterpe oleracea Mart oil (EOO) β-cyclodextrin (β-CD) or hydroxypropyl-β-cyclodextrin (HP-β-CD) by either kneading (KND) slurry (SL). Complexes were analyzed molecular modeling, Fourier-transform infrared spectroscopy, scanning electron microscopy, powder X-ray diffraction, thermogravimetry analysis differential calorimetry....
Cupuassu is a fruitful species from the Amazon basin with great economical potential, due to multiple uses of its pulp and seeds in food cosmetic industries. This fruit generates large amounts solid waste, which, despite high content bioactive compounds, discarded environment. Therefore, aim reusing these wastes adding economic value, we investigated nutritional potential seed by-product resulting industrial cupuassu oil extraction. The was submitted green extraction, contents compounds were...
Hydrogel is a biomaterial widely used in several areas of industry due to its great biocompatibility and adaptability biological tissues. In Brazil, the Calendula plant approved by Ministry Health as medicinal herb. It was chosen be incorporated hydrogel formulation because anti-inflammatory, antiseptic healing effects. This study synthesized polyacrylamide containing calendula extract evaluated efficiency bandage for wound healing. The hydrogels were prepared using free radical...
Natural products are historically regarded as the main sources of bioactive compounds to fight most diverse diseases; among them, propolis deserves be highlighted due several biological activities, such antioxidant, anti-inflammatory, healing, antibacterial and antileishmanial activity. In this study, antioxidant antipromastigote activities cytotoxicity Scaptotrigona aff. postica stingless bee were evaluated. Propolis extract was analyzed by infrared spectroscopy, thermogravimetry...
Ucuùba fat is obtained from a plant found in South America, mainly Amazonian Brazil. Due to its biocompatibility and bioactivity, was used for the production of ketoconazole-loaded nanostructured lipid carriers (NLC) view an application treatment onychomycosis other persistent fungal infections. The development optimization fat-based NLC were performed using Box-Behnken design experiments. independent variables surfactant concentration (% w/v), liquid lipids solid while outputs interest...
The industrial processing of fruits in the Amazon region, such as tucuma, generates a large amount coproducts with great nutritional potential. In this work, phenolic compounds from tucuma coproduct almonds were extracted and microencapsulated by spray drying using maltodextrin encapsulating agent verified its antioxidant activity. Phenolic determined UV spectroscopy identified Ultraefficiency Liquid Chromatography. Antioxidant activity was measured ABTS DPPH assay. Thermogravimetric...
Microparticles will probably play a promising role in the future of chemotherapy. These polymeric delivery systems are capable maximizing therapeutic activity while reducing side effects anti-cancer agents. Usnic acid (UA) is secondary metabolite produced by lichens, which exhibits an anti-tumour activity. In this study, PLGA-microspheres containing usnic from Cladonia substellata were prepared double emulsion method, with or without PEG as stabilizer. The morphology microspheres was...
Organogel (OG) is a semi-solid material composed of gelling molecules organized in the presence an appropriate organic solvent, through physical or chemical interactions, continuous net. This investigation aimed at preparing and characterizing organogel from acai oil with hyaluronic acid (HA) structured by 12-hydroxystearic (12-HSA), aiming topical anti-aging application. Organogels containing not HA were analyzed Fourier-transform Infrared Spectroscopy, polarized light optical microscopy,...
Hydrogels consist of a network highly porous polymeric chains with the potential for use as wound dressing. Propolis is natural product several biological properties including anti-inflammatory, antibacterial and antioxidant activities. This study was aimed at synthesizing characterizing polyacrylamide/methylcellulose hydrogel containing propolis an active ingredient, to serve dressing alternative, treatment skin lesions. The hydrogels were prepared using free radical polymerization,...
This study investigated thermal cracking and catalytic upgrading of waste from electric electronic equipment (WEEE) plastics on a semi-batch reactor coupled to heated catalyst fixed bed (2-stage vapor cracking). The used is Si–Al ash obtained commercial activated carbon pellets treated with concentrated NaOH solution calcination. purpose the was characterize stream through its thermogravimetry analysis pyrolysis products, effect temperature (350–500 °C) quantity (0.0–7.5 %.wt) yields...
Cupuassu (Theobroma grandiflorum Schum.) is a popular Amazonian fruit because of its intense aroma and nutritional value, whose lipid fraction alternatively used in cosmetics. To preserve active principles ensure their controlled release, extract was microencapsulated by spray drying. Influence spray-drying conditions on microencapsulation cupuassu seed by-product investigated according to 33-Box Behnken factorial design, selecting inlet temperature, maltodextrin concentration feed flowrate...
