Antimicrobial resistance has become a growing public health concern in recent decades, demanding search for new effective treatments. Therefore, this study aimed to elucidate the phytochemical composition and evaluate antibacterial activity of essential oil obtained from fruits Piper tuberculatum Jacq. (EOPT) against strains carrying different mechanisms antibiotic resistance. Phytochemical analysis was performed using gas chromatography-mass spectrometry (GC/MS). The EOPT its ability...
Background Fruit consumption is currently considered beyond the nutritional aspects because of important roles in disease prevention and benefits to health. The objective this study was characterize chemical profile evaluate antioxidant antimicrobial properties different fractions obtained from fruit pulps Mauritia flexuosa (MFFs). Methods Initially, chloroform, ethyl acetate ethanol were pulps. Quantifications total phenols flavonoids performed using methods Folin-Ciocalteu complexation...
This study presents the chemical profile of extracts from pulp and seed Annona squamosa L., as well evaluation their antioxidant acetylcholinesterase inhibition activities. In prospection, qualitative assays were performed, contents total phenols, flavonoids, vitamin C, carotenoids quantified. For compounds identification, analyses performed by liquid chromatography coupled to mass spectrometry. Antioxidant was using DPPH, ABTS, Fe3+ reduction, 2-DR protection, β-carotene protection methods....
Species belonging to the genus Lippia are used worldwide as foods, beverages, and seasonings. Studies have demonstrated that these species antioxidant, sedative, analgesic, anti-inflammatory, antipyretic activities. This work aimed evaluate antibacterial activity anxiolytic effect by different pathways of essential oils ethanolic extracts three (Lippia alba, sidoides, gracilis). The were characterized HPLC-DAD-ESI-MSn their phenolics quantified. was evaluated determining minimal inhibitory...
Psidium guajava (Myrtaceae), a common plant in Cariri region, Ceara, Brazil, as well various parts of the world, contains high concentrations bioactive compounds and many communities its are used for therapeutic purposes. Studies describe antioxidant, antimicrobial anti-diarrheal actions from extracts obtained leaves, but information about activities fruits comparison these at different maturity stages (immature, partially mature mature) scarce. This study aims to evaluate antioxidant...
This study aimed to characterize the chemical, antioxidant and antimicrobial properties of pulp oil Mauritia flexuosa L. f. (Arecaceae).Chemical identification was performed by gas chromatography coupled mass spectrometry.The physicochemical were characterized.Antioxidant capacity has been verified eliminating free radicals, reducing chelation iron.The activity evaluated minimum inhibitory concentration modulatory action antibiotics.The major fatty acids identified stearic acid, palmitic...
Abstract Cissampelos sympodialis Eichler is well studied and investigated for its antiasthmatic properties, but there are no data in the literature describing antibacterial properties of alkaloids isolated from this botanical species. This work reports isolation characterization phanostenine obtained roots C. describes first time antimicrobial antibiotic modulatory properties. Phanostenine was activities were determined. Chemical structures alkaloid isolate determined using spectroscopic...
Background: Acetylcholinesterase (AChE) acts on cholinergic hydrolysis, whose changes in its functions are related to the development of neurodegenerative diseases. Another important component these pathologies is oxidative stress, responsible for extensive cellular damage, caused by free radicals. Alkaloids represent an active source search compounds that act treatment diseases, having established antioxidant and AChE inhibitory properties. The present study aimed evaluate vitro activities...
Zingiberofficinale Roscoe and Curcuma longa L. (Zingiberaceae) essential oils were obtained by the hydrodistillation method. The offered yields of 0.120% 0.044% respectively. GC-MS analyzes allowed identification 11 constituents in oil, with major components: ar -turmerone (36.8%), β-tumerone (32.3%) curlone (19,2%) For oil 19 identified, being: neral (22.9%), zingiberene (15.5%) geranial (14.9%) main components. result toxicity test showed significant activity against Artemiasalina for both...
Auxemma glazioviana Taub. (Boraginaceae), conhecida como “pau branco”, está distribuída nos estados do Ceará e Rio Grande Norte é utilizada tradicionalmente no tratamento de cortes feridas. As distintas atividades biológicas estão associadas a presença quinonas, composto químico ampla ocorrência na espécie. O objetivo desse estudo foi identificar as principais classes metabólitos secundários, quantificar o contéudo total polifenóis, obter fração quinona (FQ) avaliar potencial antioxidante...
Antioxidant potential of the phenolic fraction Stryphnodendron rotundifolium Mart. from encapsulation in niosomes
Hymenaea courbaril L. (Jatoba) pertencente a familia Fabaceae apresenta larga utilizacao no setor florestal, sendo seu caule o produto mais comercializado por apresentar madeira de alta densidade e resistencia ao ataque organismos destruidores. No Brasil, essa especie ocorre naturalmente deste estado do Piaui ate Norte Parana. O Jatoba muito utilizado na medicina popular tratamento anemia, azia, câncer, gastrite, inflamacao dos rins, prostata infeccoes urinarias. Suas principais formas uso...
