The chemical composition of 48 essential-oil samples isolated from the leaves of Xylopia aethiopica harvested in six Ivoirian forests was investigated by GC-FID and (13) C-NMR analyses. In total, 23 components accounting for 82.5-96.1% of the oil composition were identified. The composition was dominated by the monoterpene hydrocarbons β-pinene (up to 61.1%) and α-pinene (up to 18.6%) and the sesquiterpene hydrocarbon germacrene D (up to 28.7%). Hierarchical cluster and principal component analyses allowed the distinction of two groups on the basis of the β-pinene and germacrene D contents. The chemical composition of the oils of Group I (38 oil samples) was clearly dominated by β-pinene, while those of Group II (10 samples) were characterized by the association of β-pinene and germacrene D. The leaves collected in the four inland forests produced β-pinene-rich oils (Group I), while the oil samples belonging to Group II were isolated from leaves harvested in forests located near the littoral.
采用 GC-FID 和 (13) C-NMR 分析研究了从在科特迪瓦 6 个森林中收获的 Xylopia aethiopica 叶片中分离出的 48 个精油样品的化学成分。总共鉴定出 23 种成分,占油组成的 82.5-96.1%。该成分主要由单萜烃 β-蒎烯(高达 61.1%)和 α-蒎烯(高达 18.6%)以及倍半萜烃大根香叶烯 D(高达 28.7%)组成。层次聚类和主成分分析允许根据 β-蒎烯和大根香叶烯 D 的含量将两个组区分开。组 I(38 个油样品)的油的化学成分明显以β-蒎烯为主,而组 II(10 个样品)的油则以β-蒎烯和大根香叶烯 D 的组合为特征。从内陆四个森林中采集的叶片产生了富含β-蒎烯的油(组 I),而属于组 II 的油样品则是从位于沿海地区的森林中收获的叶片中分离出来的。
