Actividad antimicrobiana y estudio fitoquímico preliminar de Mandevilla veraguasensis (Seem.) Helms. (Apocynaceae)

Abstract

Ethyl acetate extract from leaves of Mandevilla veraguasensis (Seem.) Hemsl. (Apocynaceae) has been assayed for antibacterial and antifungal activity. A moderate activity against Gram positive bacteria Bacillus subtilis, Enterococcus faecalis and Staphylococcus aureus, which can be in part attributed to the flavonoids 4´-O-methyl-kaempferol (I) and quercetin (II) isolated from this extract, was observed.
