Determination and Quantitation of Anthocyanins and Hydroxycinnamic Acids in Different Cultivars of Sweet Cherries (Prunus avium L.) from Nova Gorica Region (Slovenia)
The anthocyanins and hydroxycinnamic acids in 5 cultivars of dark coloured sweet cherries were characterised and quantified by means of HPLC and UV-VIS spectrophotometry. Phenolic components were extracted with pure methanol, without addition of acid and water. The samples were diluted in the mixtur...
