Abstract

The chemical composition of the volatile concentrates of the flowers of Dipteryx odi)rata, the cumaru (tonka) tree of the Amazon, was obtained by simultaneous distillation-extraction and analyzed by GC and GC/MS. The major components identified were germacrene D (31.1%), bicyclogermacrene (13.0%) and spathulenol (11.3%).

Key Word Index

Dipteryx odorata, Fabaceae, flower volatiles, germacrene D, bicyclogennacrene, spathulenol.

Plant Name

Dipteryx oclorata (syn.: Conwrouna odorata Aubl.), Fabaceae. Common names: cumaru, cumaru-roxo, cumaruverdadeiro, fava-tonga, muirapaje, cumbari, cumbaru, cumaruzeiro, cumaru-do-amazonas, fava-de-cumaru, paru.

Source

The flowers of D. odorata were collected at campus of Centro de Pesquisa Agroflorestal da Amazonia Oriental (CPATU/EMBRAPA), Belem (PA), Brazil. The specimen was identified in the Herbarium of Museu Paraense Emilio Goeldi by Lea Maria M. Carreira, an Amazonian Leguminosae specialist.

Plant Part

The fresh flowers of D. odorata (33.5 g) were subjected to simultaneous distillation-extraction(SDE) for 4h using a Chrompack micro-steam distillation extractor and pentane (2 mL) as organic mobile phase. This procedure was repeat once again and both SDE volatile concentrates were submitted to GC and GC/MS analysis.
