Resumo
Pterodon emarginatus Vogel, Fabaceae, is a tree species commonly
known as “sucupira-branca”. It is a popular medicinal plant in the Brazilian cerrado
(Savanna). This study investigates the chemical variability of the essential oils from
fruits of P. emarginatus. The fruits were collected from five sites in the Brazilian
Cerrado and their essential oils were analyzed by GC/MS. The results obtained by
Principal Component and Cluster Analysis identified two groups: cluster I containing
β-caryophyllene and δ-elemene and cluster II containing α-copaene, β-cubebene,
allo-aromadendrene, α-cubebene and γ-muurulene. The Canonical Discriminant
Analysis was used to differentiate between clusters on the basis of essential oil
composition. The results showed high variability in the composition of the essential
oils from fruits of P. emarginatus, contributing to studies of domestication of this
species.
