Jacaranda cuspidifolia Mart. (Bignoniaceae) as an antibacterial agent.

This study evaluated, in vitro, the antimicrobial activity of the hexane extract (JCHE), methanol extract (JCME), and chloroform fraction (JCCF) of bark from Jacaranda cuspidifolia Mart. (Family Bignoniaceae), a Brazilian medicinal plant, traditionally used as anti-syphilis and anti-gonorrhea treatment. The antimicrobial activity was evaluated using the disc diffusion method followed by the determination of minimum inhibitory concentration (MIC) values.
