The aim of this study was to perform chemical characterization Lippia alba accessions from the Active Germplasm Bank Federal University Sergipe. A randomized block experimental design with two replications applied. analysis composition essential oils conducted using a gas chromatograph coupled mass spectrometer. allowed be allocated following six groups: group 1: linalool, 1,8-cineole, and caryophyllene oxide; 2: geranial, neral, 1,8-cineol, 3: limonene, carvone, sabinene; 4: g-muurolene,...
Pelargonium graveolens l'Herit AND Lippia alba (Mill) N. E. Brown AGAINST Spodoptera frugiperda (J.E. Smith).Insecticidal activity of essential oils graveolens, and compounds geraniol, linalool, 1,8-cineole, limonene, carvone, citral Azamax ® were evaluated against frugiperda.Topical application assay showed oil P. has acute toxicity larvae (third instar) with LD 50 1.13 µg/mg per insect 90 2.56 insect.Three L. also exhibited insecticidal ranging from 1.20 to 1.56 2.60 3.75 insect.Geraniol,...
A aplicação de fertilizantes orgânicos, em plantas medicinais e aromáticas, normalmente modifica positivamente a produção vegetal óleo essencial. Neste contexto, tendo por fim avaliar resposta Plectranthus neochilus Schltr., cultivadas com diferentes fontes adubos o presente trabalho estudou biomassa, teor, rendimento composição química do As mudas, após aclimatização, foram transplantadas para vasos dez litros, acondicionados casa vegetação. O experimento foi constituído quatro tratamentos...
The efficacy of Ocimum selloi essential oil was evaluated for controlling the growth mycelia and spores germination Moniliophthora perniciosa. Six compounds (99.89%) total were identified by GC-MS, which methyl chavicol, eugenol, β-caryophyllene, germacrene-D, bicyclogermacrene spathulenol. Essential tested anti-fungal activity, determined disc diffusion minimum inhibitory concentration (MIC) determination methods. Application reduced mycelial in a dose dependent manner, with maximum...
A prática da adubação orgânica, além de fornecer nutrientes para as plantas, proporciona a melhoria estrutura física do solo, aumenta retenção água, diminui perdas por erosão e favorece o controle biológico. O elixir paregórico (Ocimum selloi Benth.) é uma espécie medicinal nativa das regiões Sul Sudeste Brasil onde utilizada popularmente como antidiarréico, antiespasmódico antiinflamatório. Este trabalho teve objetivo verificar efeito diferentes doses dois adubos orgânicos no crescimento,...
A high performance liquid chromatography (HPLC) method was developed for the simultaneous isolation, on a semi-preparative scale, of chavibetol and methyleugenol from crude essential oil P. pseudocaryophyllus leaves. The purity isolated compounds their quantifications were using GC/FID. Chavibetol with (98.7%) mass recovery (94.6%). (86.4%) (85.3%) lower than those chavibetol. Both identified basis spectral analysis. results suggest that can provide purity, recovery, productivity essential,...
Volatile organic compounds (VOCs) from leaves of geranium (Pelargonium graveolens L’ Herit) were extracted by dynamic headspace using Porapak Q (HSD-P) as adsorbent and peat, a novel in the extraction plant volatiles, analyzed gas chromatography–mass spectrometry (GC/MS) chromatography–flame ionization (GC/FID), results compared with those obtained hydrodistillation (HD). The yield volatiles changed method. HD was more efficient for extracting linalool (11.19%) citronellyl formate (9.41%)....
The plant Momordica charantia (Cucurbitaceae), popularly known as bitter melon, snake fruit, Saint Vincent's herb, or little is an African species that has developed in tropical and subtropical biomes various parts of Brazil. fruit used traditional medicinal applications. study aimed to identify the compounds essential oil leaves obtained by hydrodistillation through Solid-Phase Microextraction headspace mode (HS-SPME) coupled gas chromatography-mass spectrometry (GC-MS). analysis mature...
Ozonated oil has several benefits for humans, as it contributes to numerous interventions, maintaining the quality of life and well-being individuals. Being a natural product, few or almost no side effects. Thus, study aimed verify sensitivity and/or resistance fixed o “Ozonated” “Non-Ozonated” oils from Mauritia flexuosa (Buriti), Carapa guaianensis (Andiroba) essential Menta piperita (Mint), Eugenia caryophyllus (Clove) in different concentrations, against internationally known bacteria...
O manjericão é uma planta medicinal aromática pertencente à família Lamiaceae, rica em óleos essenciais e com grande interesse industrial. Objetivou-se, no presente trabalho, estudar a influência do processamento da folha (inteira pulverizada) submetida dois tipos secagem (estufa de ventilação forçada 38º C sala desumidificador), sobre o teor composição química óleo essencial. delineamento utilizado foi inteiramente casualizado (DIC), 4 tratamentos 6 repetições. essencial extraído por...
Background: The azadirachtin is a triterpenoid associated with growth inhibition in several kinds of insects which cause epidemic diseases like Dengue, Chikungunya and Malaria. Azadirachtin acts by inhibiting the Ecdysone Receptor (EcR), responsible from larvae phase insects. However, interaction between molecule unknown. In this work, we used program Dock Thor to generate conformations inside EcR binding site. ten most stable were optimized ONIOM approach present Gaussian 09 program. energy...
Summary The use of wild Saccharomyces a nd non‐ yeasts might result in bread with different and attractive sensory characteristics. This study aimed to evaluate the performance as starter culture dough fermentation making physicochemical parameters aromatic profile bread. All 26 strains isolated from Brazilian Cerrado fruit tree bark were osmotolerant, 19.4% able ferment maltose. Candida tropicalis ART101.3 cerevisiae SC5952 had best growth capacity under high concentrations glucose Also,...
Abstract The identification and characterization of natural products generally require the isolation pure compounds employing chromatographic techniques associated with extensive sample preparation. Preparative high‐performance liquid chromatography often allows simple complex by using little preparation or from crude extracts. Thus, this article discusses main fundamentals powerful technique, as well several applications that show plants, bacteria, fungi, marine organisms (algae, ascidian,...
Ocimum selloi is an herbal species popularly used in Brazil as antispasmodic. Herein, we report the antispasmodic effect of O. essential oil (OS) segments guinea-pig ileum. OS did not reduce tonus In contrast, reduced contraction induced by carbachol (100 μM), BaCl2 (0.03 M) and low- high-K+ concentrations (25 60 mM, respectively). shifted concentration–response curve for calcium to right a parallel manner. GC/MS analysis showed that consists mostly methyl chavicol (97.57%). These results...
