Assessment of the biopotential of wild buckthorn and prospects of its integrated use

Abstract

Sea buckthorn is a traditional raw material for the manufacture of various food and medicinal products. Juice, jams, oils, and other products are made from the berries. However, valuable biologically active substances of its bark, leaves, and branches (tannins, flavonoids, allantoin) are practically not used. On the territory of the Kaliningrad region there are vast areas of wild-growing sea-buckthorn the bio-potential of which is not used, but is of practical interest. The aim of the study is to study the chemical composition of pulp, seeds, and shell of berries, as well as to assess the content of allantoin in the bark and branches of wild buckthorn and to develop recommendations for the integrated processing of all parts of this plant. In the experiments, four samples of sea buckthorn berries from the Baltic coast collected at the villages of Yantarny, Donskoye, Filino, and at Cape Taran, as well of sea buckthorn Lekora, which grows in Germany in the Brandenburg region, were investigated. of sea buckthorn was determined by high performance liquid chromatography. It has been shown that wild buckthorn can be used for complex processing to produce biologically active compositions for the food and cosmetic industries. A complex scheme is proposed for processing the main parts of sea buckthorn to produce wine, water-soluble powder additives, and concentrates from juice; from oilcake — sea buckthorn oil; from pulp — a vitamin-mineral complex and fiber; and from branches — allantoin and fuel briquettes.
