Volatile monoterpenes from the oleoresin of Trattinnickia rhoifolia

In continuation of a search for new sources of aromatic material from the Burseraceae family (Siani et al., 1999a; Siani et al., 1999b; Ramos et al., 2000) we investigated the essential oil of the trunk exudate of Trattinickia rhoifolia Willd (Burseraceae) (Daly, 1999). Two different samples of the resin were collected (April 98 and January 99) from the same tree, in the Ducke Biological Reserve, 21 km from Manaus. The tree was catalogued by the Projeto Flora in the National Institute of Research of Amazonia—INPA, and identified by J.E.L.S. Ribeiro. A voucher specimen has been deposited at the INPA Herbarium under no. 2848.
