The uses of natural compounds, such as essential oils (EOs), are limited due to their instability light, oxygen and temperature, factors that affect application. Therefore, improving stability becomes necessary. objective this study was prepare inclusion complexes Litsea cubeba oil (LCEO) with β-cyclodextrin (β-CD) using physical mixing (PM), kneading (KN) co-precipitation (CP) methods evaluate the efficiency physicochemical properties ATR-FTIR, FT-Raman, DSC TG. also assessed cytotoxicity...
Abstract Objectives Copaiba essential oil (CEO) is obtained through the distillation of copaiba balsam and has been used in traditional medicine to treat inflammatory conditions. However, highly lipophilic nature CEO restricts its pharmaceutical use. This study evaluated effect CEO, carried a self-nanoemulsifying drug delivery system (SNEDDS), on articular systemic inflammation liver changes Holtzman rats with Freund’s adjuvant-induced arthritis. Methods Healthy arthritic received orally for...
A carne é um alimento rico em macro e micronutrientes, amplamente consumida todo mundo diferentes formas de processamento. Dentre esses processos, a maturação, consiste manter refrigerada uma temperatura específica por determinado período, promove maciez, aroma suculência agradável ao consumo. O objetivo deste trabalho foi avaliar percepção dos consumidores sobre o consumo carne, especificamente da dry aged. Para isso, realizado estudo descritivo para levantamento informações variáveis...
There is an increasing demand for fungi control in grains, especially toxigenic. Also, there growing concern on the use of synthetic fungicides; thus alternatives are needed. The aim this study was to evaluate antifungal and antimycotoxigenic action essential oils (EOs) from Zingiber officinale, Cinnamomum zeylanicum Cymbopogon martinii against Fusarium verticillioides, a spoilage toxigenic fungus. Essential were first chemically characterised by gas chromatography coupled mass spectrometry,...
The purpose of this study was to determine the chemical profile Litsea cubeba essential oil, carry out an in vitro evaluation its antioxidant potential and cytotoxicity, as well antifungal antimicotoxigenic activities against Fusarium verticillioides. Most compounds observed EO were neral (32.75%) geranial (37.67%). radical scavenging capacity 2,2-diphenyl-1-picrylhydrazyl 2,2′-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid 104.4 56.4 mmol Trolox mg−1, respectively, indicating good...
This study aimed to evaluate the antimycotoxigenic effect of essential oils (EOs) obtained from four different aromatic plants on production deoxynivalenol (DON) and zearalenone (ZEA) by
An essential oil complex (EOP) of Cymbopogon martinii with β-cyclodextrin (β-CD) was evaluated as a strategy to stabilize the Palmarosa and increase its bioactivity. The complexation methods used were co-precipitation kneading, and, for comparison, physical mixing carried out. To confirm molecular inclusion, techniques combined characterization inclusion complex, such Fourier Transformer Raman Spectroscopy (FT-Raman), Attenuated Total Reflection Transform Infrared (ATR-FTIR), Differential...
In the present study, biological activity of an extract secondary metabolites (E-G6-32) produced by Curvularia sp. G6-32 endophyte (isolated from medicinal plant Sapindus saponaria L.) was investigated. The antioxidant potential confirmed DPPH (22.5%) and ABTS (62.7%) assays, total phenolic compound content 40 µg gallic acid equivalents/mg. E-G6-32 displayed good inhibitory toward butyrylcholinesterase (BuChE; IC50 = 110 ± 0.05 mL-1). subjected to spectroscopic mass spectrometry analyses....
This study was to evaluate the biological activity of extract Botryosphaeria fabicerciana isolated from leaves Morus nigra. The volatile compounds crude were analysed by GC-MS which demonstrate that mellein and β-orcinaldehyde are major compounds. best minimum inhibitory concentration (MIC) bactericidal (MBC) observed against Gram-positive bacteria, with a MIC 15.6 μg/mL towards B. cereus 62.5 S. aureus subtilis. MBC values 31.25 μg/mL, 250 cereus, subtilis, aureus, respectively....
Iron is a fundamental microelement for human life; however, deficiencies or excesses of these metal ions can cause severe complications and mortality. Chelators are compounds that bind inhibit iron. Ultraviolet-visible (UV-vis) spectrophotometric methods key analytical tools in the identification chemical entities, with benefits having good precision accuracy, equipment being easily available as well quick simple to implement. In this study, we aimed provide an alternative, cheaper method...
The use of rosemary essential oil (RO) and its combination with nisin (RO+N) in preventing the multiplication Alicyclobacillus acidoterrestris orange juice was evaluated. minimum inhibitory bactericidal concentrations (MIC MBC) for RO were both 125 μg ml−1 while RO+N displayed a synergistic effect. at 1, 4 8× MIC 96 h evaluated terms their sporicidal effectiveness. With regard to action against A. spores, sporostatic, whereas 1× sporicidal. Morphological changes structure micro‐organism...
Solanum americanum Mill. is a plant that belongs to the Solanaceae family, its respective ripe fruit dark purple. Ripe S. fruits were submitted physicochemical characterisation, and their trans-resveratrol contents quantified by high-performance liquid chromatography. Such determination was executed with at different stages of ripeness freeze-stored as well. In natura pulp peel presented average amounts 1.07 0.7960 μg per gram sample, respectively. These are significantly higher when...
The aim of this study was developing formulations H. undatus Haw. jam with pulp and peel, as well evaluating nutritional compounds texture properties through sensorial, instrumental, physical, biochemical microbiological analyses the final product. fruit were selected, sanitized, pulped grinded, different concentrations peel (0 – 100%) developed evaluated. Microbiological evaluation showed that are in accordance current legislation. increase concentration resulted better consumer acceptance...
Aims: This study aimed at evaluating the physicochemical characteristics of dragon fruits with application different types covering and submitted to two refrigeration temperatures. Study Design:The were taken, selected, washed, cleaned a solution Sodium hypochlorite 1%, dried then, treated coverings based on manioc starch 2%, jelly 2% conservative (1% ascorbic acid, 0.5% citric 0.7% sodium chloride 0.25% calcium chloride) by immersion during 2 minutes. There was also control treatment, that...
