ABSTRACT

Content and composition of free phenolic acids fraction as well as tannins in leaves (blades and leaf stalk) of two celery cultivars (Helios and Zefir) were evaluated in studies. It was found that tannin levels in both raw materials were from 2.09 to 7.42%, but leaf stalks contained about 3-fold more than blades. Also content of free phenolic acids sum was determined in raw material. Studies revealed that blades contained about 3-fold more phenolic acids than leaf stalks. Such results could point that celery might be of chemopreventive properties.

Key words: Apium graveolens, phenolic acids, chemoprevention, antioxidants, high-performance liquid chromatography (HPLC).
