Chemical Constituents of Essential Oil of<i>Protium decandrum</i>(Burseraceae) from Western Amazon

Abstract

Abstract The chemical composition of essential oils obtained from the leaves (leaflets and rachis), branches and resin of Protium decandrum (Aubl.) Marchand, Burseraceae, growing in the Amazon forest were examined by GC-MS. The oils extracted from leaves showed varying content of tenpin-4-ol (rachis: 64.8 %; leaflets: 33.0 %). The sesquiterpene trans-α-bergamotene was the major component identified in the oil from branches (22.1 %) and resin (47.7 %).
