Abstract

The chemical compositions of essential oils and absolutes of the flowers of Bombax costatum harvested in N'Tonimba, N'Tabacoro and Sanankoroba (Mali) were determined by gas chromatography (GC) and gas chromatography coupled with mass spectrometry (GC/MS). Forty-two components were identified in the essential oils from which the majority are linear alkanes such as docosane (9.28 to 17.34%), heneicosane (9.18 to 17.28%), tricosane (7.06 to 13.09%), tetracosane (3.62 to 7.62%). Forty-five compounds in which the absolute. The majoritary components are hexadecanoic acid (23.04 to 25.38%), dehydroaromadendrene (7.11 to 12.10%) and ethyl oleate (7.94 to 10.36 %). The chemical compositions of essential oils and the absolute are different.
