Vegetable crops are of immense importance for human health, foremost because they are a rich source of bioactive compounds. Parsley is notable among other vegetable species for its vitamin C content. It also contains minerals (potassium, sodium, magnesium, phosphorus), essential oils (-pinene, -myrcene, -phellandrene, -pinene), beta carotene and vitamin E. Parsley is grown for its leaf lamina and root. The objective of this research was to determine the content of bioactive and chemical compounds (dry matter, soluble dry matter, total acidity, vitamin C, phenols, non-flavonoids, flavonoids, total chlorophylls, chlorophyll a, chlorophyll b, total carotenoids and antioxidative capacity) in root, petiole and leaf lamina among three root parsley cultivars ('Halblange', 'Arat' and 'Eagle') and three leaf parsley cultivars (curled-leaf parsleys 'Mooskrause' and 'Petra' and flat-leafed parsley 'Rialto'). Results of the research show high content of vitamin C in leaf lamina of 'Rialto' cultivar (162,09 mg/100g vitamin C), total phenols in leaf laminas of all tested cultivars (304,57 to 425,76 mg/L) and high lighting the parsley petiole of root parsleys cultivars ('Hablange', 'Arat', 'Eagle') in content of total phenols (151,22 to 165,12 mg/L). Regarding pigment compounds, the content of total chlorophylls and carotenoids was examined and the leaf lamina of all researched cultivars had several times higher content of total chlorophylls and carotenoids compared to the petiole. All parsley cultivars show high antioxidative capacity due to significant amounts of bioactive compounds such as chlorophylls, carotenoids, phenols, flavonoids, non-flavonoids and vitamin C.
