The Sabinene Chemotype of Essential Oil of Seeds of Daucus carota L. ssp. carota Growing Wild in Lithuania

Abstract

The composition of the essential oil of Daucus carota L. ssp. carota seeds (fruits) collected from ecologically clean localities and in polluted areas near the roads was analyzed by GC and GC/MS. The oils from all samples were of the sabinene (28.2–37.5%) chemotype. The other major constituents were α-pinene (16.0–24.5%), terpinen-4-ol (4.6–7.5%), γ-terpinene (2.9–6.0%) and limonene (2.3–4.0%). The oils consisted of 83.4–95.1% monoterpenoids (monot-erpene hydrocarbons made up 60.5–74.8%) and 3.4–10.5% sesquiterpenoids. The ratio of sesquiterpenoids and monoterpenoids from clean localities and from the areas near the roads was found to be different (probably due to pollution). Identified compounds made up 92.1–99.5% of the oil.
