Abstract (English):
The review provides brief information about willow trees of the Salicaceae family, noting their diversity and large habitats (56 genera and about 1220 species of willow trees (Scyphostegiaceae)). In terms of chemical composition willow trees contain a large number of valuable phenolic compounds - biologically active substances: salicin, quercetin, kaempferol, phenologlycosides, flavanoids, as well as related substances: malic acids, tannins, essential oils and others, allowing to influence the biological processes occurring in a living organism. These substances have anti-inflammatory, regenerating, soothing, analgesic properties. Due to these properties they have a high added value and a wide range of applications in various industries: in medical and pharmaceutical industries as anti-inflammatory and antibacterial agents, to enhance blood supply to the retina, prevent cataract formation, activate cellular and tissue immunity; in cosmetics for the care of problem skin areas, as a means of strengthening hair; in agriculture for the manufacture of feed additives and compound feeds; in food as a food additive; in foodstuffs for the production of foodstuffs and fodder. For the extraction of these components, many extraction methods with appropriate apparatus design are currently used. However, they do not take into account the specificity of the initial raw materials, the combination of components in them. This leads to high cost of extraction process of separate pure components (the price of 1 kg of salicin is 390 ,1kgofquercetin−5000, 1 kg of kaempferol - 3846,2 $). In this connection the development of new technologies for extraction of biologically active substances is actual. To assess the quality of extraction of biologically active substances, the authors offer various analytical methods and ways of analysis using modern apparatuses: high-performance liquid, thin-layer and gas chromatography; photometric (spectrophotometric and photocolorimetric) methods and nuclear magnetic resonance methods.
