What is it about?
The essential oil (EO) of the flowers of Banisteriopsis campestris was analysed by GC and GCThe EO inhibited the growth of all tested oral bacteria, showing strong activity against S. sanguinis with minimum inhibitory concentration (MIC) of 25 μg mL-1. Considerable antibacterial activity was also observed for the anaerobes Porphyromonas gingivalis and Actinomyces naeslundii with MIC of 50 μg mL-1. The EO of B. campestris flower showed moderate activity for S. mutans, S. mitis, A. actinomycetemcomitans and Fusobacterium nucleatum with MICs ranging between 200 and 400 μg mL-1.-MS. The main constituents were hexadecanoic acid (39.43%), (E)-nerolidol (10.51%), triacontane (9.08%), heptacosane (5.49%) and linalool (3.23%). The antifungal activity was evaluated against C. albicans, C. tropicalis and C. glabrata. The MIC results were above 3000 μg mL-1, indicating inactivity against these yeasts.

Why is it important?
This study revealed that the OE of B. campestris flowers has promising antibacterial activity and this is the first report on its chemical composition and antimicrobial activity.
Perspectives
The EO of the flowers of B. campestris presented relevant activity against the aerobic and anaerobic oral bacteria tested and did not indicate any anti-Candida activity. These results contributed to the chemical and biological knowledge of the species B. campestris that is endemic to the Brazilian Cerrado.
