Samples of five species of the genus of Psidium (Myrtaceae) are analyzed for essential oils. The foliar oil of P. cattleianum Sabine is dominated by β-caryophyllene (59.92±1.70%). The foliar oil of P. friedrichsthalianum (Berg) Niedenzu is dominated by β-caryophyllene (36.82±19.44%) and α-pinene (10.61±13.70%). The foliar oil of P. guajava L. is dominated by β-bisabolene (19.21±2.44%) and β-sesquiphellandrene (14.75±0.01%). The foliar oil of P. guineense Sw. is dominated by β-bisabolene (13.18±2.00%) and α-pinene (12.85±5.42%). The foliar oil of P. sartorianum (Berg) Niedenzu is dominated by α-pinene (16.66±1.05%), β-caryophyllene (12.35±2.82%) and α-phellandrene (9.81±1.13%).
