Abstract

The essential oil of Cleistopholis patens (Annonaceae) leaves was obtained by hydrodistillation using a traditional still from leaves collected in the Gagnoa department, Cote dIvoire, with a yield of 0.21%. Chemical analyses were carried out by gas chromatography-mass spectrometry (CPG-MS) and carbon-13 nuclear magnetic resonance (13CNMR). Sixteen compounds, accounting for 95.75% of the total composition, were identified. The chemical profile is characterized by a balanced distribution between hydrocarbon monoterpenes (34.88%) and hydrocarbon sesquiterpenes (36.84%), complemented by oxygenated sesquiterpenes (21.18%) and an aromatic hydrocarbon, naphthalene (5.13%). The major constituents were p-cymene (14.36%), caryophyllene (10.77%), and 3-carene (9.23%). The essential oil of Cleistopholis patens from Gagnoa exhibited pronounced bactericidal activity, attributed to its chemical diversity, notably the presence of compounds well recognized for their effectiveness against a variety of microbial agents.
