Aroma compounds in the essential oil of carrots (Daucus carota L. ssp. sativus). 1. Leaves in comparison with roots.

Carrot leaves (Daucus carota L. ssp. sativus) have significantly higher essential oil contents compared with the roots. There are differences between varieties. Leaves of Nanco' F have higher essential oil contents than leaves of 'Cubic'; but roots of 'Cubic' have higher essential oil contents than roots of 'Nanco'. Leaves and roots are different in the qualitative and quantitative composition of the essential oils. Therefore, the prediction of the cultivar-specific flavour of roots by analyzing the leaves, is not possible. Changes, occuring in the carrot root and leaf during growth, were shown for essential oil content and some flavour compounds.
