Chemical profile and antimicrobial activity of Secondatia floribunda A. DC (Apocynaceae)
Objective: To establish the chemical profile, and to evaluate the antibacterial and modulatory activity of the ethanolic extracts of the stalk's inner bark and heartwood of Secondatia floribunda. Methods: Quantification of total phenols and flavonoids was determined by the Folin-Ciocalteu metho...

Antibacterial assays for determination of the Minimum Inhibitory Concentration (MIC) and modification of aminoglycosides were performed by microdilution.

The antibacterial activity showed clinically significant results for the strains of Staphylococcus aureus and Escherichia coli.

Conclusions: This study is the first report of chemical and biological information of Secondatia floribunda suggesting that it is clinically relevant source of a new antibacterial therapy, especially due to the presence of significant levels of phenolic compounds.
