Background. Honeysuckle is a promising berry crop for food and medical uses, which has recently become increasingly popular. Searching for sources with high content of bioactive substances to obtain new fruit cultivars with improved chemical composition continues to be relevant. Anthocyanin content and composition in honeysuckle cultivars depend on many factors, including plant reproduction conditions (temperature and humidity). Studying chemical composition of Siberian honeysuckle cultivars grown under the conditions of Western Siberia will make it possible to identify sources of high BAS content for various uses.Materials and methods. The target materials of the study were fruits of 21 honeysuckle cultivars grown in Western Siberia before and after freezing. The qualitative and quantitative composition of anthocyanins was assessed in ethanol extracts of honeysuckle fruits using HPLC technique.Results. The content of anthocyanins was higher in the fruits of honeysuckle grown in Western Siberia compared with the published data for the same cultivars reproduced in Belgorod Province (Central Black Earth Region). After freezing, the anthocyanin level in honeysuckle fruits remained the same and in some cases even increased.Conclusions. The obtained data helped to ascertain that honeysuckle fruits reproduced in Western Siberia are valuable sources of such bioactive compounds as anthocyanins.
