Carrot seed was extracted with the solvents 1,1,2‐trichloro‐1,2,2‐trifluoroethane (TTE), methylfuran (sylvan), ethanol and dichloromethane. After evaporation of the solvent, the resinoids obtained were steam distilled to separate the volatile components. The chemical composition of the essential oil samples obtained using the different solvents, as well as that obtained by hydrodistillation, were compared. Quantitatively, the highest yields of concrete and essential oil were obtained using sylvan (4.79% and 0.47%) and ethanol (3.30% and 0.87%). These yields of essential oil are greater than those obtained by hydrodistillation (0.40%). Some of principal components varied in amount with the extraction solvent used. For example, GC‐MS analysis showed that the contents of α‐pinene were 2.47% (sylvan), 0.25% (TTE), 0.30% (EtOH), trace (CH 2 Cl 2 ) and 13.31% (hydrodistillation). Those of geranyl acetate were (the same order as above) 23.58%, 3.48%, 12.08%, 10.11%, and 10.39% and those of carotol were 13.97%, 40.91, 39.06%, 31.75%, and 18.29% respectively.
