Essential oils of Hymenaea courbaril and Syzygium cumini Gustavo Oliveira Everton

This study evaluated the antimicrobial, antioxidant and toxicity activity of essential oils (EOs) of Hymenaea courbaril L. var. courbaril bark and Syzygium cumini (L.) Skeels leaves. The major constituent of the EO of H. courbaril was ?-ocimene (23.33%) and the EO of S. cumini was isocaryophyllene (18.01%). Both EOs showed efficient antioxidant activity and toxicity against Artemia salina. The EOs showed bactericidal activity against E. coli, S. aureus, P. aeruginosa, Salmonella sp., B. cereus and P. mirabilis. The results obtained are encouraged by the potential use of the OE's studied in the control and fight of pathogenic microorganisms.
