The aim of this study is to determine the chemical composition of essential oils of Chaerophyllum ‎khorassanicum belonging to the Apiaceae family for the first time. Identification of essential oils ‎is necessary, for food, cosmetics- health industry, and medicinal uses. The plant was collected at ‎the flowering stage of Khorassan Razavi Province in Iran, Farizi Village. The shoot parts of the ‎specimen were dried in the laboratory and crushed to particles. The essential oils were obtained ‎by hydro-distillation using Clevenger and analyzed by GC-MS. Fifty-one components were ‎identified in Chaerophyllum khorassanicum essential oils which accounted for ۹۷.۲% of the ‎essence. The major chemical category of the volatile compounds were the monoterpene ‎hydrocarbons (۶۵.۵%), followed by oxygenated monoterpenes (۲۴.۵%). In particular, the main ‎components were limonene ۳۲.۱%, methyl eugenol ۱۶.۲%, and β-Ocimene ۱۵.۶%. In conclusion, ‎monoterpene hydrocarbons are characteristic and represent excellent chemotaxonomical markers ‎for Chaerophyllum khorassanicum.
