Abstract: Prunus padus L., is not very popular plant, it is commonly found due to low soil requirements and easy to settle in various places. As for now, concerning food technology, there is no wide application for P. padus . Therefore, the aim of this study is to evaluate the possibility of using bird cherry bark as an ingredient in herbal functional teas. In the first step, the conditions for extraction of the bark were electrochemically optimized. It was proven that the highest content of polyphenols could be found in the sample consisting of chamomile, linden flower, and calendula (7939.8 ± 106.6 mg/100 g dm). In the beta-carotene bleaching test, the highest activity could be spotted for calendula tea (16.7 ± 1.1 c %) and chamomile tea (15.0 ± 2.0 c %) and concerning the test for linden flower tea without added bark (134.4 ± 15.1 b μg ascorbic acid /mL). The property of the tested teas to inhibit cholinesterases was proven. What is more, P. padus bark infusion showed the highest activity of 15.8 ± 1.1 d μg neostigmine/mL, for acetylcholinesterases (AChE) inhibition and 21.2 ± 1.0 c μg neostigmine/mL for butyrylcholinesterases (BChE). The same tea also showed the highest activity to reduce ions of iron (Fe(III)): 25.3 ± 0.9 c μg Trolox /mL and glutathione reductase and glutathione peroxidase inhibition, 87.0 ± 1.1 e % and 64.9 ± 2.0 d % respectively. The use of P. padus bark may be vital in the preventive care concerning modern-age diseases and allow for the production of a new range of products with distinctive sensory characteristics and functional properties and, at the same time, in combating the spread of P. padus in the farm and forest ecosystem.
