Essential oils obtained by hydrodistillation of leaves of two Nigerian species were analyzed for their constituents by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The leaf oil of Ficus benjamina L. (Moraceae), collected during the day, contained high contents of α-pinene (13.9%), abietadiene (9.7%), cis-α-bisabolene (8.2%) and germacrene-D-4-ol (8.4%), while the night sample was dominated by germacrene-D-4-ol (31.5%), 1,10-di- epi-cubenol (8.8%) and hexahydrofarnesylacetone (8.3%). This could be a possible indication of differences in emissions of volatiles by F. benjamina during the day and night. The main compounds of Irvingia barteri Hook. f. (Irvingiaceae) were β-caryophyllene (17.0%), (E)-α-ionone (10.0%), geranial (7.6%), (E)-β-ionone (6.6%) and β-gurjunene (5.1%).

The goal of this study was to investigate the essential oil compositions of different parts (stem, leaf, flower and mixture) of Lavandula x intermedia in Bismil-Diyarbakır,Turkey. The chemical composition of essential oils obtained by hydrodistillation from fresh Lavandin samples were analyzed using gas chromatography-mass spectrometry (GC/MS). The results indicate the major components of the studied parts of lavandin was; linalool (24.97-2.52-43.86-39.43 %), linalyl acetate (3.,4-0.29-9.37-15.76 %), eucalyptol (33.81-43.81-18.47-12.08 %), camphor (13.12-15.91-8.72-9.21 %), endo-borneol (2.03-5.18-0.68-1.24 %) and alpha-terpineol (2.84-2.47-1.28-3.86 %) in essential oils of stem, leaf, flower and mixture parts of fresh lavandin respectively. It was understood that linalool and linalyl acetate level were the highest in flower and mix parts while eucalyptol, camphor and endo-borneol levels were the highest in stem and leaf parts of the plant.
