ABSTRACT
In years 1999-2001 a scientific experiment with two cultivars of celery, ‘Zefir’ and ‘Helios’ was carried out. We traced the changes of the content and composition of essential oil comprised in leaves, taking into account the length of vegetation period of the above plants. It appeared that the biggest amount of essential oil was contained in the youngest leaves: 0.34% (‘Zefir’ cv.) and 0.30% (‘Helios’ cv.). It was also observed that he older plants in the moment of their collection, the lower content of essential oil. With help of chromatographic analysis the experiment allowed to indicate three fractions: monoterpene, sesquiterpene and phtalid fraction. Limonene appeared to be a dominant component of essential oil obtained from celery leaves independently of the collection date.
Key words: celery, vegetation period, essential oil, monoterpene, sesquiterpene, phtalide.
