The use of medicinal plants in Brazil has been around for a long time, but this handling is not always used properly. Thus, studies in this area have high growth over the years and cover not only the composition of species already used, but also others with potential to be applied in medicinal treatments. The essential oils present in the leaves of aromatic plants are usually extracted by the steam-dragging technique and have in their composition several metabolites such as phenols, terpenes, alkaloids, polyacetylenes, fatty acids, peptides, among others, to which they can be attributed. antioxidant and pharmacological activities. Among these constituents, they have strong inhibitors of the enzyme acetylcholinesterase, and make them effective in the treatment of Alzheimer's disease. They act to slow the hydrolysis of acetylicoline by reducing its levels at nerve endings (where electrical stimulation is generated in the nerves, which is uninterrupted and causing damage to the nervous system) and increasing in synapses that cause high neural stimulation. , this study aims to analyze the efficiency of anticholinesterase activity of essential oils of plant species: Macrosyphonia velame (velame), Lavandula spp. (alfazema brava) e Astronium fraxinifolium (Gonçalo Alves).
