Antioxidant and antiradical activity of Heracleum sosnowskyi inflorescences in the Murmansk region

At present, there is an increased interest in the study of plant extracts in order to find promising sources of biological compounds for the pharmaceutical, cosmetic and food industries. Sosnowsky’s hogweed (lat. Heracleum sosnowskyi Manden.) is a large herbaceous plant capable of accumulating a large volume of green biomass. Presumably, during the period of mass flowering of inflorescences, plants are in greater need of antioxidant and antiradical protection. The aim of this study was to investigate the antioxidant and antiradical activity of substances contained in the inflorescences of H. sosnowskyi Manden., growing in the Murmansk region. It was shown that during the period of mass flowering of the main inflorescence of H. sosnowskyi Manden., the content of compounds with antioxidant activity reaches higher values in the harsh conditions of the Khibiny than on the foothill plain. The data obtained will allow improve understanding of the peculiarities of plant metabolism in the conditions of the Kola Peninsula and to develop modern technologies for the extraction of biologically active compounds from the inflorescences of H. sosnowskyi Manden., growing in the Murmansk region.
