The chemical composition of 48 leaf oil samples isolated from individual plants of Cleistopholis patens ( Benth .) Engl. et Diels harvested in four Ivoirian forests was investigated by GC‐FID (determination of retention indices), GC/MS, and 13 C‐NMR analyses. The main components identified were β ‐pinene (traces–59.1%), sabinene (traces–54.2%), ( E )‐ β ‐caryophyllene (0.3–39.3%), linalool (0.1–38.5%), ( E )‐ β ‐ocimene (0.1–33.2%), germacrene D (0.0–33.1%), α ‐pinene (0.1–32.3%), and germacrene B (0–21.2%). The 48 oil compositions were submitted to hierarchical clustering and principal components analyses, which allowed the distinction of three groups within the oil samples. The oil composition of the major group ( Group I , 33 samples) was dominated by ( E )‐ β ‐caryophyllene and linalool. The oils of Group II (eight samples) contained mainly β ‐pinene and α ‐pinene, while those of Group III (seven samples) were dominated by sabinene, limonene, and β ‐phellandrene. Moreover, the compositions of the Ivoirian C. patens leaf oils differed from those of Nigerian and Cameroonian origins.
