Compostos fenólicos e atividade antioxidante de extratos brutos de Ocimum gratissimum L. (Alfavaca) produzidos por maceração dinâmica e banho ultrassônico

Abstract

Medicinal plant species have been an important alternative for the treatment of various pathologies. Ocimum gratissimum L. is a woody shrub known as Alfavaca, alfava-clove or basil used in folk medicine to treat pneumonia, fever, diarrhea and malaria. These therapeutic uses are due to the fact that these species are a source of secondary metabolites such as flavonoids, terpenoids, steroids, tannins and phenolic compounds. Thus, the objective of this study was to verify the content of phenolic components and analyze the antioxidant activity in extracts and crude methods of O. gratissimum L. leaves, comparing two study methods, mac and ultrasonic bath. In the combination of respectively superior phenolic compounds, the result obtained by the dynamic maceration method was performed by ultras bath (232.5 mg EAG-1 and 160.3 mg EAG g-1, activity the same as a (38.5 mg of EBHT g-1 for dynamic maceration and 16.4 mg of EBHT g-1 for ultrasonic bath, published by the Reducing Power test; 132.3 mg of EBHT g-1 for dynamic maceration and 89.8 mg of EBHT g-1 for ultrasonic bath, known for the desfomolybd Complex test). Therefore, the extractive methods used interfere with the results obtained and demonstrate that O. gratissimum L. is a medicinal plant that needs to be learned with therapeutic potential.
