Chemical characterization, toxicity, antioxidant and antimicrobial activity of the essential oils of Hymenaea courbaril L. and Syzygium cumini (L.) Skeels

This study evaluated the antimicrobial, antioxidant and toxicity activity of essential oils (EOs) Hymenaea courbaril L. var. bark Syzygium cumini (L.) Skeels leaves. The EOs were extracted by hydrodistillation chemically characterized gas chromatography coupled to mass spectrometry (GC/MS). ABTS DPPH assay used evaluate activity. For assay, lethality was against Artemia salina Leach. antimicrobial method Disc Diffusion Dilution in Broth applied obtain minimum inhibitory concentration bactericidal. major constituent EO H. β-ocimene (23.33%) S. isocaryophyllene (18.01%). Both OE showed relevant low salina. bactericidal E. coli, aureus, P. aeruginosa, Salmonella sp., B. cereus mirabilis. results obtained are encouraged potential use OE's studied control fight pathogenic microorganisms.
