The aromatic flora of the Amazon has been inventoried for 30 years. In this sense, were made over 500 field trips to collect 2500 plants and obtain more than 2000 essential oils aroma concentrates, all them submitted GC GC-MS. This work led creation a database Amazon, which catalogs general information about 1250 specimens. allowed publication chemical composition aromas 350 species, associated with larger number types. many species offer optimum conditions economic exploitation use in...
Eugenia uniflora L. is a member of the Myrtaceae family and commonly known as Brazilian cherry tree. In this study, we evaluated chemical composition essential oil (EuEO) by using gas chromatography-mass spectrometry (GC-MS) assessed its anti-Leishmania activity. We also explored potential mechanisms action cytotoxicity EuEO. Thirty-two compounds were identified, which constituted 92.65% total composition. The most abundant components sesquiterpenes (91.92%), with curzerene (47.3%), γ...
The essential oils of the fresh and dry flowers, leaves, branches, roots Lippia thymoides were obtained by hydrodistillation analyzed using gas chromatography (GC) GC–mass spectrometry (MS). acetylcholinesterase inhibitory activity oil leaves was investigated on silica gel plates. interactions key compounds with simulated molecular docking dynamics studies. In total, 75 identified, oxygenated monoterpenes dominant components all plant parts, ranging from 19.48% to 84.99%. roots, main...
The essential oil of Siparuna guianensis was obtained by hydrodistillation. identification the chemical compounds performed gas chromatography coupled with mass spectrometry (GC/MS). Antimicrobial activity investigated for four microorganisms: Streptococcus mutans (ATCC 3440), Enterococcus faecalis 4083), Escherichia coli 25922), and Candida albicans (ATCC-10231). studies doping molecular dynamics were molecule that presented highest concentration drug–target proteins, 1IYL (C. albicans),...
Models validation in QSAR, pharmacophore, docking and others can ensure the accuracy reliability of future predictions design selection molecules with biological activity. In this study, pyriproxyfen was used as a pivot/template to search database Maybridge Database for potential inhibitors enzymes acetylcholinesterase juvenile hormone well. The initial virtual screening based on 3D shape resulted 2000 Tanimoto index ranging from 0.58 0.88. A new reclassification performed overlapping...
Abstract Bignonia nocturna (Bignoniaceae) is a plant used for medicinal purposes by the Amazonian indigenous peoples. To date, there have been no reported studies on its toxicity. The present study aimed to evaluate chemical composition of essential oils obtained from different extraction techniques. In addition, an in silico molecular interactions was performed using docking and dynamics. extractions were carried out hydrodistillation, simultaneous distillation‐extraction, steam...
Essential oils (EOs) were extracted from Eugenia patrisii, E. punicifolia, and Myrcia tomentosa, specimens A B, using hydrodistillation. Gas chromatography coupled with mass spectrometry (GC/MS) was used to identify the volatile constituents present, antioxidant capacity of EOs determined diphenylpicryl-hydrazyl (DPPH) trolox equivalent (TEAC) assays. For germacrene D (20.03%), bicyclogermacrene (11.82%), (E)-caryophyllene (11.04%) identified as major specimen A, whereas B primarily...
The essential oils of eight samples Piper aduncum L., collected at different localities the Amazon region, were analysed by GC–MS. major component identified in all was dillapiole (31.5–97.3%). Sample A, Serra do Navio (AP), showed a yield oil and content 3.3% 31.5%, respectively; sample B, Melgaço (PA), 1.8% 50.8%; C, Benfica 1.6% 56.3%; D E, Belém 1.2% 82.2%; 1.5% 86.9%, F, Manaus (AM), 3.4% 91.1%; G, Road Manaus-Caracaraí, km 30 3.0% 97.3%; H, Cruzeiro Sul (AC), 3.2% 88.1%. P. occurring...
The essential oils (EOs) of the aerial parts Lippia origanoides (LiOr), collected in different localities Amazon region, were obtained by hydrodistillation and analyzed GC CG-MS. Principle component analysis (PCA) based on chemical composition grouped four chemotypes rich mono- sesquiterpenoids. Group I was characterized 1,8-cineole α-terpineol (LiOr-1 LiOr-4) group II thymol (LiOr-2). oil LiOr-3 showed β-caryophyllene, α-phellandrene β-phellandrene as predominant LiOr-5 (E)-nerolidol...
