Bioactive and chemical compounds content in different parsley cultivars (Peteroselinum crispum Mill.)

Abstract

Povrtne kulture su važne za ljudsko zdravlje, a prvenstveno jer su bogat izvor bioaktivnih spojeva, pa tako i peršin koji se među ostalim povrtnim vrstama ističe u sadržaju vitamina C. Sadrži i minerale (kalij, kalcij, magnezij, fosfor), eterična ulja (-pinen, -mircen, -felandren, -pinen), beta karoten te vitamin E. Uzgaja se zbog lisnih plojki i korijena. Cilj ovog istraživanja bio je utvrditi sadržaj bioaktivnih i kemijskih spojeva (sadržaj suhe tvari, topljive suhe tvari, ukupnih kiselina, pH, vitamina C, fenola, neflavonoida, flavonoida, ukupnih klorofila, klorofila a, klorofila b, ukupnih karotenoida te antioksidacijskog kapaciteta) u korijenu, peteljci i lisnoj plojki kod tri sorte peršina korjenaša, ('Halblange', 'Arat' i 'Eagle') i tri sorte peršina listaša (kovrčavih liski 'Mooskrause' i 'Petra' te glatkih liski 'Rialto'). Rezultati istraživanja pokazuju visok sadržaj vitamina C u lisnoj plojci sorte 'Rialto' (162,09 mg/100g vitamina C), visok sadržaj ukupnih fenola u lisnim plojkama svih istraživanih sorti (304,57 do 425,76 mg/L ukupnih fenola) te isticanje peteljki sorti peršina korjenaša ('Halblange', 'Arat', 'Eagle') prema sadržaju ukupnih fenola (151,22 do 165,12 mg/L ukupnih fenola). Od pigmentnih spojeva istraživan je sadržaj ukupnih klorofila i karotenoida, a lisne plojke svih sorti imale su nekoliko puta veći sadržaj ukupnih klorofila i ukupnih karotenoida u odnosu na peteljke. Sve sorte peršina pokazuju visoki antioksidacijski kapacitet zato što sadrže značajne količine bioaktivnih spojeva poput klorofila, karotenoida, fenola, flavonoida, neflavonoida i vitamina C.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
