The content of the mentioned compounds should be higher in 100 g of solid extracts than in 100 g of fruits. Thus, the presented work concerns the evaluation of total polyphenols and anthocyanins contents in black chockeberry--Photinia melanocarpa (Michx.) extract--dietary supplement (DS) available on market.

The usage of certain conditions of measurements such as dilution factor, storage conditions and filtration, has the significance in the determination of the analyzed compounds in the extract.
