Combined analysis of Xylopia aethiopica trunk bark oil by chromatographic and spectroscopic techniques
نویسندگان
چکیده
The chemical composition of four oil samples of Xylopia aethiopica isolated from trunk bark harvested in three Ivoirian forests was investigated by chromatographic (GC with retention indices) and spectroscopic techniques (MS, 13C NMR). Thirty compounds accounting for 90.2-98.2% of the oil have been identified. X. aethiopica stem bark produced a monoterpene-rich essential oil, whose composition was dominated by βpinene (37.0-61.6%) and α-pinene (13.0-19.3%). Two samples out of four contained also 3,3-dimethyl-1vinylcyclohexene (up to 6.4%) and 4,4-dimethyl-2-vinylcyclohexene (up to 12.7%).
