Abstract
The aim of this study was to identify and determine the qualitative and quantitative composition of furanocoumarins in anatomical parts (blade and petiole) of two cultivars of ribbed celery, depending on the age of the plant. Two accurate, precise and inexpensive techniques for analytical detection of coumarin in a relatively short period of time were used in the present study. TLC - the method considered as preliminary, showed the presence of psolaren, bergapten, xanthotoxin and simple coumarin - umbelliferone. Additionally, isopimpinellin was detected by HPLC method. Chromatographic analysis of ribbed celery leaves showed the presence of four furanocoumarins. Psoralen and isopimpinellin are dominant in the leaf blades, wherein content is correlated with the term of harvesting. Bergapten was dominant in petioles regardless of the harvesting time and cultivar.
