Abstract: The essential oil extracted by hydrodistillation from the leaves of Piper guineense Schumach. & Thonn. (Côte d’Ivoire) showed a yield of 2.00 ± 0.01% (w/w). Combined analysis using gas chromatography–mass spectrometry (GC-MS) and ¹³C nuclear magnetic resonance (¹³C NMR) spectroscopy enabled the identification of 41 volatile compounds, classified into five groups: sesquiterpenes (92.46%), diterpenes (4.53%), monoterpenes (2.74%), linear alcohols (0.25%), and linear hydrocarbons (0.29%). The major constituents were hydrogenated azulene (20.54%), β-caryophyllene (19.54%), 1-(1-methylethyl)-4, 7-dimethyl-1,2,3,5,6, 8a-hexahydronaphthalene......
