Chemical composition of the leaf oil of Artabotrys jollyanus from Côte d’Ivoire

ABSTRACT One oil sample isolated from leaves of Artabotrys jollyanus Pierre, Annonaceae, from C ôte d ’ Ivoire has been analyzed by GC(RI), GC-MS and 13C NMR. In total, thirty-seven compounds accounting for 96.9% of the relative composition have been identified. The composition of the essential oil was dominated by trans-calamenene (15.7%), α -copaene (14.8%), α -cubebene (10.4%), cadina-3,5-diene (10.3%), (E)- β -caryophyllene (6.3%) and cadina-1,4-diene (6.1%). 13C NMR spectroscopy was very useful in the identification of trans-calamenene, 7-hydroxycalamenene, cadina-3,5-diene and cadina-1,4-diene. Moreover, monitoring the evolution of the leaf essential oil composition and the yield on a 12-month period (one sample per month) was achieved. The twelve essential oil samples exhibited a chemical homogeneity but the yield varied from sample to sample (0.26 – 0.60%).
