The aim of this study was to evaluate the quality of selected commercial products made from elderberry fruits and flowers, in terms of their bioactive properties. The research covered products available on the market, including juices, syrups, jam, mousse and confiture. The evaluation was based on measurements of antioxidant activity, total polyphenols content, as well as anthocyanins content and profile. The antioxidant activity was highly correlated with the content of polyphenols in the tested products. The highest values of these parameters were shown by one of five juices, which was directly pressed from organic fruit. The least phenolic compounds, and thus the weakest antioxidant properties, were found in the case of syrups, especially elderflower syrup. The highest content of anthocyanins, depending on the test method used, was observed in the mentioned juice and jam, whereas the lowest amounts of these compounds or their absence were recorded in confiture, mousse and pharmaceutical syrup.
