Essential oil of Cymbopogon citratus collected from Brazil and Cuba was tested to a chemical characterization then on the post-embryonic development Musca domestica. The composition analysis by GC-MS oils Brazil/Cuba allowed identification 13 12 major constituents respectively; nine them common both. In both oils, main components were isomers geranial neral, which together form compound citral. This corresponds total 97.92%/Brazil 97.69%/Cuba compounds identified. monoterpene myrcene,...
Manilkara subsericea (Mart.) Dubard (Sapotaceae) is popularly known in Brazil as "guracica." Studies with spp indicated the presence of triterpenes, saponins, and flavonoids. Several activities have been attributed to such antimicrobial, antiparasitic antitumoral, which indicates great biological potential this genus. In all, 87.19% hexanic extract from fruits relative composition were evaluated, 72.81% beta- alpha-amyrin esters, suggesting that they may be chemical markers for M....
Based on the ethnopharmacological evidences about antileishmanial activity of Copaifera spp. oleoresins, effects crude extracts and fractions oleoresin two specimens from paupera were evaluated Leishmania amazonensis infantum strains. The rich in α -copaene (38.8%) exhibited best against L. (IC 50 = 62.5 μ g/mL) 65.9 g/mL). sesquiterpene isolated was tested alone high vitro with IC values for 17.2 11.4 g/mL, respectively. In order to increase activity, nanoemulsions containing copaiba...
This work compares the chemical composition of essential oils from leaves Licaria canella collected in two different seasons. The results this investigation were compared with leaf other species Lauraceae family, Aniba canelilla, at same time. Both analyzed by GC-FID and GC-MS. demonstrated a larger predominance benzenoids, being main constituent benzyl benzoate for L. 1-nitro-2-phenylethane A. canelilla. comparison biological activities showed that (IC50 19 µg mL-1) was more active against...
Copaifera oleoresin is one of the most used natural products in popular medicine all over world. Among other effects (i.e., anti-inflammatory, antinociceptive, microbicidal) well-known its wound healing capacity. However, mechanism by which presents effect still not clear. In this study, our aim was to evaluate capacity obtained from paupera, action and identify major components. For these purposes, diabetic Swiss Webster mice were topically treated with (100, 150 or 200 mg/kg) for 14...
The difficulties encountered and the numerous side effects present in treatment of cutaneous leishmaniasis have encouraged research for new compounds that can complement or replace existing treatment. growing scientific interest study plants, which are already used folk remedies, has led our group to test Endlicheria bracteolata essential oil against Leishmania amazonensis. Several species Lauraceae family, their compounds, relevant antiprotozoal activities Therefore, biological potential on...
• Origanum vulgare and Thymus vulgaris show significant adulticidal activity. Important repellent activity of essential oil. Morphological differences highlighted in the larvae treated with oils. Essential oil two spices can be used to control A. aegypti mosquitoes. The high incidence dengue, chikungunya, Zika indicates importance controlling vector these arboviruses tropical subtropical regions world. However, is hindered by pesticide resistance limited success biocontrol programs against...
Promastigote forms of Leishmania amazonensis were treated with different concentrations two fractions Curcuma longa cortex rich in turmerones and their respective liposomal formulations order to evaluate growth inhibition the minimal inhibitory concentration (MIC). In addition, cellular alterations promastigotes investigated under transmission scanning electron microscopies. LipoRHIC LipoRHIWC presented lower MIC, 5.5 12.5 μ g/mL, when compared nonencapsulated (125 250 g/mL), respectively,...
Species of the genus Alpinia are widely used by population and have many described biological activities, including activity against insects. In this paper, we describe bioactivity essential oil two species genus, A. zerumbet vittata, Rhodnius nasutus, a vector Chagas disease. The oils these were obtained hydrodistillation analyzed GC-MS. main constituent (OLALPZER) was terpinen-4-ol, which represented 19.7% total components identified. vittata (OLALPVIT) monoterpene β-pinene (35.3%)...
Chrysomya megacephala represents a major threat to public health. It is mechanical vector of various pathogens, such as viruses, bacteria, and protozoan cysts, while their larvae may cause myiasis. The alternative synthetic insecticides, which are harmful the environment man`s health, use natural insecticides that safe for both. Plant derivatives have gained prominence in this field, but little known about how diluents used formulations can influence insecticidal activity, physiology...
Echium hypertropicum Webb and stenosiphon subsp. are capeverdian shrubs used in folk medicine for the treatment of cough gastrointestinal diseases. Acid-base extraction was to obtain alkaloid-rich fractions from both species. GC–MS ESI-MS/MS analysis indicated presence pyrrolizidine alkaloids (PAs) purified substances were also analyzed by 1D 2D NMR experiments. A total ten detected, eight which identified comparing their molecular masses mass fragmentation patterns with NIST database data...
To evaluate the acaricidal activity of essential oil obtained from roots Derris floribunda (D. floribunda) (Miq.) Benth, and its main constituent nerolidol against Mexican mite Tetranychus mexicanus (T. mexicanus) (McGregor). The D. collected in Amazon region (Brazil) was by hydrodistillation. Its chemical composition determined GC–MS analysis. activities this nerolidol, were evaluated recording number dead females (mortality) eggs (fertility). showed sesquiterpenes as major volatile...
Leaves surfaces, which represent an interface with plants and the environment, have several structures specific functions. Some foliar properties, including wettability mechanical containment, are inferred in terms of cellular adaptation presence or absence cuticular wax. Various morphological parameters, ranging from macro- to nano scales, analyzed contribute study taxonomy, pharmacognosy, ecology plants. The aim this paper was analyze effect influence epicuticular wax granules on...
Spondias mombin Linn (Anacardiaceae) is a plant species found from southeastern Mexico to Peru and in the northern of Brazil. Its fruits are known as "cajá miúdo" or pequeno" Brazil; Central America, "jobo"; "hogplum" "yellow mombin" North America; "ciruella amarilla" Ecuador, among others. It used by local population treat diseases due its many biological properties, such antiviral, anti-inflammatory, antioxidant, antibacterial properties. This study was carried out using databases, indexed...
