Abstract
The aim of the work is to develop an optimal technology for extracting a complex of substances with an antioxidant effect from cranberries (Vaccinium oxycoccos L.), sea buckthorn (Hippophaërhamnoides L.), blackberries (Rubus subgen. Rubus), honeysuckle (Lonicera L.) widespread in the Russian Federation. ), viburnum (Viburnum opulus L.), mountain ash (Sorbus aucuparia L.), juniper (Juniperus L.), a comparative study of the effect of ultrasound exposure with traditional maceration and microwave irradiation on the total content of phenols, flavonoids, anthocyanins, β-carotene, antiradical e action, restoring force in the extraction of the studied plant materials. Spectrophotometric methods for determining the total content of phenols, flavonoids, anthocyanins, antiradical activity with 2,2-diphenyl-1-picrylhydrazyl free radical, and restoring forces with the FRAP reagent were chosen as research methods. It is the use of ultrasonic extraction for fruits that allows to obtain a higher content of phenols, flavonoids, anthocyanins, antiradical activity values, regenerating power, antioxidant action in the obtained extracts. Microwave radiation has a similar effect in the level of a number of indicators of fruit extracts. Although the performance of microwave extracts of fruits is lower in magnitude than ultrasonic extracts. It is interesting to note that it is anthocyanins as the most sensitive to external influences class of compounds that are extracted during ultrasonic processing from the berries and remain the most. To obtain fruit extract, acting as a component of many dietary supplements, as well as cosmetics with a high level of antioxidant substances and antioxidant activity, on the basis of the conducted research it is possible to recommend ultrasonic treatment as an intensification method with the same temperature parameters and process time, which will allow to obtain extracts with a higher content of nutraceutical substances.

Целью данной работы являются: сравнительные исследования показателей общего содержания фенолов, флавоноидов, антирадикальной активности по улавливанию свободного радикала 2,2-дифенил-1-пикрилгидразила, восстанавливающей силы, антиоксидантной активности для плодов клюквы (Vaccinium oxycoccos L.), облепихи (Hippophaë rhamnoides L.), ежевики Исследования содержания флавоноидов проводят по методу J.C.P. Calado et al [21] с модификацией для экстракта плодов. Для всех изученных плодов и ягод и технология экстракции с использованием ультразвуковой обработки дает наилучшие показатели общего содержания фенольных веществ.
