Chemical Profile of Essential Oils and Headspace Volatiles of Chaerophyllum hirsutum from Serbia

The present study reports the chemical composition on the headspace volatiles and essential oils obtained from fresh roots, shoots and inflorescences of Chaerophyllum hirsutum. In headspace samples, the most dominant class was monoterpene hydrocarbons, but the main compounds were different. The root had β-phellandrene as the major compound. Sabinene was the main component in the shoots volatiles, while the inflorescence was dominated by endo-fenchyl acetate. The composition of the essential oils of the aerial parts and the oil obtained from root was found to be quite different. The root essential oil showed the presence of phenolic compounds (13.2%), while in the oils from the aerial parts these compounds were present in very small amounts (0.1% in the shoots and 0.2% in the inflorescences oil). In total, 70 compounds were identified in the oil isolated from the root, with γ-terpinene (15.8%) as the major compound of the oil. In the oils isolated from the shoots and the inflorescences, for which 55 and 69 compounds were identified, respectively, the main class was represented by oxygenated sesquiterpenes with acorenone B as the main component, representing 57.0% of the shoots and 44.6% of the inflorescences.
