Abstract

Introduction. Plant raw materials can be a source of biologically active substances and increase the nutritional value of food products. The present research objective was to determine the content of biologically active substances in powdered viburnum and barberry.
Study objects and methods. The study featured viburnum (Viburnum opulus L.) and barberry (Berberis vulgaris L.), dried by convection and crushed into particles of 50 microns.
Results and discussion. The total content of phenolic compounds in powdered viburnum was 3114.07 mg/100 g, in powdered barberry – 2272.7 mg/100 g. The content of flavonoids in powdered viburnum was 324.52 mg/100 g, in powdered barberry – 390.00 mg/100 g. The flavonoid profile of the powders included rutin, hyperoside, quercitrin, isoquercintrin, and astralagin. The total content of catechins was 446 mg/100 g for viburnum and 506 mg/100 g for barberry. The catechins included mainly epigallocatechin and catechin. In powdered viburnum, the catechin composition was as follows: epicatechin – 196, catechin – 118, and epigallocatechin – 89 mg/100 g; in powdered barberry: epigallocatechin – 173, catechin – 111, and epicatechin – 74 mg/100 g. The antiradical activity in relation to trolox equivalent was 7560 mg/100 g in powdered viburnum and 9460 mg/100 g in powdered barberry.
Conclusion. The obtained viburnum and barberry powders can fortify food with biologically active substances and expand the range of functional products.
