Antimicrobial compounds detected in Bocconia arborea extracts by a direct bioautographic method.

Abstract

The methods allows for the detection of spots of growth inhibition of cultures directly in the extract thin layer chromatographic plate previously dispersed with a broth culture containing the microorganisms. The procedure also allowed for the detection of the presence of several products in the B. arborea extract with considerable activity against five different microorganisms. Additionally, the method allowed the determination that the antimicrobial activity is due to compounds of probable alkaloid origin.
