ABSTRACT:

Leaves essential oils of Syzygium cumini L. Cupressus sempervirens L. and Lantana camara L., from Alexandria, Egypt were analysed by Gas chromatography-mass spectrometry (GC-MS). The antibacterial and antioxidant activities were assessed for each oil using minimum inhibitory concentrations (MICs) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) methods; respectively. The main oil constitutes were alpha-pinene (17.53%), alpha-terpineol (16.67%) and alloocimene (13.55%) in S. cumini, trans-caryophyllene (15.57%) and alpha-humulene (9.16%) in L. camara and cedrol (21.29%), delta3-carene (17.85%) and alpha-pinene (6.9%) in C. Sempervirens. The antibacterial activity was studied against some bacterial strains. The oil of S. cumini demonstrated strong inhibition activity against the tested bacterial strains. The total antioxidant activity (TAA %) was 11.13, 9.13, 3.13% for S. cumini, L. camara and C. sempervirens, respectively. Our work revealed that the studied leaf oils are new promising potential sources of antioxidants and antibacterial compounds and good future practical applications for human and plant health.
