Abstract The chemical composition of the essential oils from the leaves from three different populations of Psidium laruotteanum Cambess. (Myrtaceae) from the Brazilian Cerrado were analysed by GC-FID and GC-MS. Forty-five components were identified in the oils. The oil yields were 0.3% (dry weight basis). The oil was rich in monoterpenes and major compounds identified were p-cymene (19.4–34.8%), 1,8-cineole (6.9–19.2%) and α-pinene (9.2–11.4%). Although collected in different locations and years, the essential oils composition were quite similar, both qualitative and quantitatively.
