The healing properties of extracts from sea buckthorn fruits have been confirmed by numerous studies, however, the infertile parts remaining after harvesting or after pruning young trees also contain valuable components. Leaves, bark, shoots and woody parts of sea buckthorn are very promising raw materials for the extraction of biologically active substances. The introduction of non-waste technologies, issues of resource conservation, the search for rational ways to isolate valuable components from the non-fruit part of sea buckthorn determined the relevance of this study. The choice of the optimal method for the extraction of non-fruit parts of sea buckthorn is aimed at accelerating heat and mass transfer processes and increasing the rate of diffusion extraction of biologically active substances. The paper reflects the results of experimental studies of traditional aqueous extraction of non-fruit parts of sea buckthorn, namely leaves, bark, shoots and wood, and the results of intensification of extraction by preliminary freezing of the feedstock. The influence of the raw material freezing rate on the size of the formed ice crystals is analyzed. It has been established that at a freezing rate of 0.1-1 cm/ h, large ice crystals form in the intercellular space of plant raw materials, causing mechanical damage to cellular structures and contributing to better leaching of biologically active substances, which is confirmed by experimental studies.
