چکیده:

In this work extraction of clove oil from clove buds has carried out by water / hydrodistillation and supercritical fluid extraction methods. In the measurements effect of several parameters such as heating power (120, 200, 250, 400 and 600 W) (for water/hydro distillation method), and pressure (90, 120, 150 bar) (for supercritical fluid extraction method) on the extraction yield and the content of eugenol in extracts are investigated. Compositions of essential oil of clove buds are detected by gas chromatography (GC). The results show that the heating power is effective on the eugenol content in the distillated extracts. The maximum of eugenol extracted by hydro distillation is obtained in heating power of 600W.
