Scents from Brazilian Cerrado: chemical composition of the essential oil from Psidium laruotteanum Cambess (Myrtaceae)

摘要

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 -pinene (9.2-11.4%). Although collected in different locations and years, the essential oils composition were quite similar, both qualitative and quantitatively.
