The objective of this study was to determine, by GC/MS, the composition of the essential oil (EO) of two plants obtened by hydrodistillation and steam distillation. The main objective is to promote two Ivorian species. The organoleptic quality, yield and chemical composition of essential oils (EO) extracted from Mischogyne elliotiana and Daniellia ogea by hydrodistillation (HD) and steam distillation (SD) have been determined. EO yields are (HD: 0.012% - SD: 0.11%) for Mischogyne elliotiana and (HD: 0.06% - SD: 0.05%) for Daniellia ogea. Essential oils have been analyzed by Gas Chromatography-Mass Spectrometry. Essential oils obtained by hydrodistillation revealed more compounds than those obtained by steam distillation: Mischogyne elliotiana (HD: 32 compounds - SD: 24 compounds), Daniellia ogea (HD: 40 compounds - SD: 38 compounds). The essential oils of Mischogyne elliotiana consist mainly of sesquiterpenes. The hydrocarbon sesquiterpene content is: (HD: 87.18% - SD: 94.27%). Oxygenated sesquiterpenes: (HD: 9.98% - SD: 3.76%). Daniellia ogea EO is made up of oxygenated sesquiterpenes (HD: 34.14% - EV: 32.64%), diterpenes (HD: 2.07% - SD: 0.51%) and other compounds (HD: 7.15% - SD: 11.47%). Hydrocarbon monoterpenes (0.15%) are present only in the oil obtained by hydrodistillation. The main compounds in Mischogyne elliotiana EO obtained by hydrodistillation are α-gurjunene (58.14%) and β-guaiene (8.26%), while those obtained by steam distillation are α-gurjunene (50.60%) and β-guaiene (8.30%). In Daniellia ogea essential oils, the main compounds obtained by hydrodistillation are caryophyllene oxide (19.91%), β-caryophyllene (17.83%) and β-farnesene (15.56%), while those obtained by steam distillation are also caryophyllene oxide (18.92%) and β-caryophyllene (15.87%). The study on Mischogyne elliotiana essential oil is described for the first time.
