We review the consequences of environmental changes caused by human activities on forest products and forest-dependent communities in Amazon region—the vast Amazonas River basin Guiana Shield South America. used 2018 2021 Intergovernmental Panel Climate Change reports recent scientific studies to present evidence hypotheses for ecosystem productivity geographical distribution plants species. have identified species associated with highly employed exhibiting reducing populations, mainly...
The genus Dipteryx, to which the cumaru tree belongs, contains neotropical species native Central and South American countries. They are used both in sale of timber seeds for extraction active compound coumarin, as a flavoring agent. This study evaluated phytochemical profile antioxidant activity extracts leaves, branches, fruits (residues seeds) Dipteryx punctata. plant material analysis was collected five seed-producing areas, Mojuí dos Campos, Pará, Brazil. were obtained via Soxhlet...
Nos últimos anos, consumidores de produtos coloridos aumentaram a rejeição ao uso corantes artificiais. Ao mesmo tempo, coloração alimentos e cosméticos principalmente, utilizando fontes naturais contendo diferentes classes pigmentos, ganhou importância na indústria. Embora os pigmentos possuam estabilidade inferior se comparados aos sintéticos, conquistam cada ano uma nova fatia do mercado. Problemas como temperatura, oxigênio luz são fatores que afetam negativamente qualidade aparência dos...
Pyrrolizidine alkaloids (PAs) often serve as chemical mediators of plant-herbivore-predator interactions. Butterflies (Danainae and Ithomiinae) moths (Arctiidae) usually acquire PAs from plant sources (larval host plants, flowers or withered leaves visited by adults—pharmacophagy) thereby become chemically protected against predators; they also use pheromone precursors. Study GC-MS in three species Ithomiinae butterflies, their larval plants adult alkaloid showed different acquisition...
Lippia grandis Schauer is an aromatic plant that has been used as a spice in Brazilian culinary and traditional medicine to treat liver disease, disorders of the stomach throat infections. We determined chemical composition essential oil L. evaluated its potential for treatment clinically-important pathogenic micro-organisms. The was obtained by hydrodistillation analyzed gas chromatography-mass spectrometry (GC-MS), giving carvacrol (37.12%), ρ-cymene (11.64%), thymol (7.83%) main...
The oil from the seeds of "Andiroba" tree, which is found throughout most tropical America, contains high levels unsaturated triacylglycerols (TAG), makes it attractive to cosmetics industry. A significant amount limonoids also confers this Amazonian several pharmaceutical and medical properties. In addition, a potential feedstock for biodiesel production, its many uses have intensified extractive exploitation in recent years. Herein we report on characterization TAG, free fatty acids (FFA)...
Rosewood oil (RO) (Aniba rosaeodora Ducke) is rich in linalool, a monoterpene alcohol, which has well studied anxiolytic, sedative and anticonvulsant effects. The inhibition of the increases cAMP protects against seizures diversity models epilepsy. In this paper, principal aim was to investigate effects RO, (±)-linalool (-)-linalool) on adenylate cyclase. They were tested chick retinas forskolin used stimulate enzyme target. phosphodiesterase inhibitor,...
ABSTRACT Copaiba oleoresin is a natural product widely used in traditional Amazonian medicine the treatment and cure of various ailments, having biological activities such as anti-inflammatory, cicatrizant, antiseptic antimicrobial. Cancer one main public health problems, being cause thousands deaths around world. In view pharmacological properties copaiba oleoresin, investigation its anticancer potential may be an alternative for obtaining new phytopharmaceuticals. The objective this work...
ABSTRACT The aim of this study was to determine the anesthetic efficacy essential oils (EOs) Aniba rosaeodora (EOAR) and parviflora (EOAP) one their main compounds, linalool, in two forms: synthetic extracted from EOAR (linalool-AR) tambaqui (Colossoma macropomum). In first experiment, induction recovery juveniles exposed 25- 200 µL L-1 or 50- 300 EOAP linalool linalool-AR evaluated. second experiment observed behavioral effects long-term exposure (12h) these EOs linalools (5 10 L-1). Fish...
Oral diseases are one of the biggest public health problems worldwide, caused by opportunistic pathogens such as Streptococcus mutans and Enterococcus faecalis. Cyperus articulatus (priprioca) is a plant conventionally used in traditional medicine Amazon region. However, little known about possible dentistry-related uses extracts from rhizomes solid waste generated extraction essential oils this vegetable. This study aimed to investigate chemical composition volatile compounds antimicrobial...
Dermacentor nitens (tropical horse tick) is a tick species commonly found parasitizing horses and other equids in the Amazon region, causing economic losses. Currently, control based on chemical acaricides, usually power formulation for topical use. However, its indiscriminate use results emergence of resistant lineages. Several plant compounds have been tested their acaricide activity. In Amazon, several plants are used oil extraction, resulting production solid residue (waste) that may...
Arrabidaea chica (crajiru) is an important Amazonian plant. Its extracts are used as red pigments, antimicrobial agents and astringents. Three different varieties of this species cultivated in the Amazon region. In work, direct infusions A. from these three were analyzed via electrospray ionization mass spectrometry (ESI(+)-MS) fingerprinting. Derived data spectra classified by using a multivariate method (PLS-DA, partial least squares-discriminant analysis). The that herein presented relies...
ABSTRACT Malaria is a disease of global tropical distribution, being endemic in more than 90 countries and responsible for about 212 million cases worldwide 2016. To date, the strategies used to eradicate this have been ineffective, without specific preventive measures such as vaccines. Currently, existing therapeutic arsenal limited has become ineffective against expansion artemisinin-resistant Plasmodium, demonstrating need studies that would allow development new compounds disease. In...
