Infraspecific chemical variability in the essential oils of Pimenta pseudocaryophyllus (Gomes) L.R. Landrum (Myrtaceae)

► Infraspecific chemical variability of Pimenta pseudocaryophyllus from Brazil was investigated. ► GC and GC-MS analysis of leaf essential oils identified mainly phenols and monoterpenes. ► Multivariate analysis identified three chemotypes: citral, (E)-caryophyllene, and (E)-methyl isoeugenol. ► The chemovariation observed can be genetically determined. ► Chemical and biological future studies with this species should specify the chemotype.
