• Abstract

• Among the many species of medicinal plants, the cashew tree stands out (Anacardium occidentale L.) belonging to the Anacardiaceae family, commonly used in traditional medicine as analgesic, anti-inflammatory and aphrodisiac. The objective of the research was to analyze the metabolites present in the plant extracts of the leaves, flowers and cashew through phytochemical screening. The botanical material was collected from a productive individual in the municipality of Santana, in the Nova Brasília neighbourhood, located in the southern part of the State of Amapá. For identification and incorporation purposes the material was sent to Herbarium of Amapá (HAMAB). Extracts of the leaf, flower and of the cashew tree were obtained: 400g of leaves, 100g of flowers and 500g of tree bark, at each determined time, were cleaned and set to dry under the influence of sunlight for 7 days and then from this stage the material was taken to the oven at 48 ºC for 72 hours for the dehydration process and then crushed in an industrial blender. It was left to steep for 7 days in a hydroalcoholic solution until it covered all the organic material at room temperature. The extracts were subjected to investigation of chemical constituents by metabolic class. The tests were carried out in triplicate and followed the conditions established in the Manual for Phytochemical and Chromatographic Analysis of Plant Extracts. From the leaves, a yield of 5.46 % BSE was obtained, which showed a powdery appearance, brownish-green. Phytochemical screening for BSE of cashew leaves revealed positive results for the presence of saponins, phenols and tannins, alkaloids and flavonoids. From the flowers, a 19.36 % BSE yield was obtained, which appeared as a brownish-green powder. Phytochemical screening of BSE of cashew flowers revealed positive results for the presence of organic acids, reducing sugars, alkaloids and phenols and tannins. And, the tree bark obtained a yield of 4.23 % of BSE, which showed the appearance of brownish powder. Phytochemical screening of BSE from tree bark revealed positive results for the presence of reducing sugars, organic acids and phenols and tannins. The performance of phytochemical screening identified the presence of secondary metabolites, such as saponins, phenols, tannins, alkaloids and flavonoids present in the leaves; and organic acids, reducing sugars, alkaloids, phenols and tannins present in flowers and bark.
