The essential oil of Zanthoxylum armatum was extracted through hydro distillation and analyzed by GC-MS. Hydrocarbon fraction (17.35%) of the oil was much lower and oxygenated compounds comprised fairly high portion of essential oil (39.21%). Percentages of monoterpenes and sesquiterpenes found were 47.33% and 10.83% respectively. Oxygenated monoterpenes comprised major profile of chromatogram of essential oil of Zanthoxylum armatum i.e. 37.23% where as monoterpene hydrocarbons were 10.09%. Alcoholic percentage was much higher i.e. 26.76% and 15-hexadecanoloide (6.58%) the only cyclic ester was found in relatively high percentage.
