Compostos fenólicos, flavonoides, antocianinas e atividade antioxidante de extratos brutos de Croton antisyphiliticus Mart (pé-de-perdiz) produzidos por maceração dinâmica e ultrassom

Abstract

Plants of the genus Croton stand out for their richness and diversity in secondary metabolites being the target of many studies. The Croton antisyphiliticus Mart (Pé-de-perdiz) plant, in medicine, is popularly used for the treatment of some sexually transmitted diseases and infections of the female and male reproductive system. Knowing that the therapeutic potential of a plant may be related to the presence of secondary metabolites, the present work aimed to quantify the content of secondary metabolites such as flavonoids, anthocyanins, and total phenolic compounds, in addition to the antioxidant activity, in the crude extract obtained by both extraction in ultrasonic bath, or by dynamic maceration of the C antisyphiliticus Mart plant from two different locations. The method of extraction by dynamic maceration showed statistically significant results, being more efficient than the ultrasonic bath method. Although the means fluctuated for the two different locations, there was no statistical interference in the results considering the collection site. The C. antisyphiliticus Mart plant had a content of phenolic compounds, flavonoids and anthocyanins in its crude extract and also demonstrated to have antioxidant capacity in all parts analyzed. Throughout the work, the raw extract of the leaves showed to be more promising than the other parts and in its majority the extracts obtained by the process of dynamic maceration obtained greater averages. . Thus, in view of all the analyzes carried out, it is suggested that the medicinal plant C. antisyphiliticus Mart should continue to be investigated for future use to obtain new drugs and also be used in the food industry due to its antioxidant potential.
