Chemical composition of the essential oil extracted from the seeds of Monodora myristica (Gaertn.) dunal (Annonaceae) harvested in the mountain district in Côte d'Ivoire

Abstract

As part of a contribution to the valuation of aromatic and medicinal plants of the Ivorian flora, our interest focused on the extraction and determination of the chemical composition by GC / MS of the essential oil has been extracted from the seeds of Monodora myristica. The yield of the essential oil is (1.43±0.08) %. Chemical analysis of the essential oil has identified 32 compounds. This corresponds to 99.96% of the total constituents. The phytochemical composition consists of hydrocarbon monoterpenes (77.47%), oxygenated monoterpenes (11.43%), hydrocarbon sesquiterpenes (6.54%), 0.55% oxygenated sesquiterpenes and other compounds (3 .99%). The chemical composition is dominated by hydrocarbon monoterpenes (77.47%). The major phytocompounds are ortho-cymene (39.54%), α-phellandrene (25.81%), α-pinene (5.6%) and α-terpineol (5.51%). The presence of phenolic hydroxy compounds, alcohol and sesquiterpenes would justify the use of the species in traditional medicine.
