The essential oils of six species of Protium (Burseraceae), collected near Manaus, Amazon,
were extracted by hydrodistillation and analysed by GC–MS. Resins from four species were
collected yearly, and two species were represented by more than one tree. All six oils were
found to be entirely monoterpenoid in constitution and were characterized by the
predominance of p‐cymene and α‐and β‐phellandrene. The composition of fresh exudates

Abstract
The essential oils of six species of Protium (Burseraceae), collected near Manaus, Amazon, were extracted by hydrodistillation and analysed by GC – MS. Resins from four species were collected yearly, and two species were represented by more than one tree. All six oils were found to be entirely monoterpenoid in constitution and were characterized by the predominance of p‐cymene and α‐ and β‐phellandrene. The composition of fresh exudates is associated with increasing content of α‐pinene and unsaturated p‐menthanes. Copyright © 2000 John Wiley & Sons, Ltd.
