Organic products are recognized by consumers as safer (e.g. free from pesticide residues) as well as richer compounds important for human health. The fruit juices are one of the best source of bioactive compounds like polyphenols (phenolic acids, flavonoids and anthocyanins), as well as vitamins (especially vitamin C). In the experiment four types of fruit juices were tested: chokeberry juice, apple-chokeberry juice, clear apple juice and clear apple juice with addition of green tea extract. The dry matter content of the juices was measured and moreover the content of vitamin C and polyphenols were measured by HPLC method. The obtained results show that apple juice with addition of green tea extract in comparison to the other analyzed fruit juices contained significantly more dry matter, total flavonoids and individual phenolic acids as: gallic and caffeic as well as luteolin,. The chokeberry juice in comparison to the other tested juices contained significantly more vitamin C, total anthocyanins and all of the individual anthocyanins, total phenolic acids as well as the individual phenolic acids: p-coumaric, ferulic, cinaminic, myrycetin and apigenin. Whereas clear apple juice contained significantly more chlorogenic acid and quercetin than other tested fruit juices.
