Caraway (Carum carvi L., Apiaceae) is a very popular spice and herb, which is widely applied in the food and pharmaceutical industry. Variations in the essential oil content and composition in twenty commercial caraway samples obtained from retail pharmacies and health shops in different countries were determined using hydrodistillation and capillary GC techniques.

The main components of the oils in caraway seeds were carvone (44.5–95.9%) and limonene (1.5–51.3%). Between the content of carvone and limonene the negative correlation -0.999 (p<0.01) was found. Additionally, β-myrcene (0–0.4%), trans-dihydrocarvone (0–0.5%), and trans-carveole (0–0.2%), as well as α-pinene, sabinene, n-octanal, trans-β-ocimene, γ-terpinene, linalool, cis- and trans-limonene oxide, cis-dihydrocarvone, cis-carveol, perillaldehyde, trans-anethole, and trans-β-c...
