Antioxidant and antibacterial activity of Myrcianthes pungens leaf essential oil

Myrcianthes pungens (Myrtaceae) is a native tree to Brazil known as guabijú. In our study, we described the chemical composition of essential oil from M. dried leaves, antioxidant activity by different methods and antibacterial against Staphylococcus aureus, Bacillus cereus Pseudomonas aeruginosa. The identification was done gas chromatograph coupled mass spectrometer evaluated broth microdilution method. leaf presented hydrocarbon sesquiterpenes (42.6%) its main class whose major compounds were β-caryophyllene (11.7%) 1,8-cineole (10.1%). best protection 57.5 63.3% β-carotene. highest S. aureus (MIC 78.12 µg/mL). This value 2.56-fold lower than positive streptomycin control. promising source natural molecules with potential study for development pharmacological, cosmetic food products.
