used to obtain high added value products ( Rivas et al., 2008 ). One of the recovered products from citrus peels is essential oil. Essential oil is the volatile fraction of a plant; oil is present in oil-filled pit or oil glands located in different peel depths, which have to be broken to retrieve these bags and release the oil ( Coll et al., 1995 ; Sahraoui et al., 2011 ). Then, oil is obtained by physical separation processes. Typical processes for obtaining essential oils include different cold pressing and distillation techniques, followed by purification processes

, sterols, glycosides and brain esters, etc. As far as the essential oil of this plant was rarely studied, which chemical constituent is more complicated [ 7 ]. This essay concentrated on chemical constituent of essential oil. First, we used steam distillation to extract the tubers, petioles, leaves, and fruits of Arisaema Amuremse Maxim and obtained the essential oil. Then the essential oil was extracted by diethyl ether, dried with anhydrous sodium sulfate, and analyzed by GC - MS. Finally, the antineoplastic activities of the essential oils were tested by MTT assay [ 8
