Antifungal and antibacterial activity of the floral ethanolic extract of Mandevilla pohliana (Stadelm.) A. H. Gentry

Abstract

Mandevilla pohliana is a species belonging to the Apocynaceae family found in Cerrado environments. The bjetive of this study was to evaluate the antifungal and antibacterial action of the floral ethanolic extract of M. pohliana. Flowers of M. pohliana were collected and the ethanolic extract produced by maceration. In different concentrations of extract, antifungal of the genus Candida were determined, and antibacterial activities on Escherichia, Salmonella, Enterococcus, Pseudomonas and Staphylococcus. Antibiosis activity was observed only for C. guilliermondii with 9-2 mm, for P. aeruginosa with 12-3 mm and for E. faecalis between 10-3 mm at the highest concentrations between 50-500 mg mL^-1. The floral ethanolic extract of Mandevilla pohliana showed potential as a natural antifungal and antibacterial agent.
