Abstract

Agro-industrial waste at all stages of agricultural production, processing and consumption increases annually and reaches an enormous level. Agricultural waste is often rich in valuable biologically active substances, therefore, it is important to consider methods of its efficientprocessing. Waste recycling is required to reduce the negative impact on the environment, minimize waste and increase the efficiency of the use of raw materials. The paper presents the results of chemical analysis of phytogenic waste: potato and carrot tops. Potato and carrot top wastes are considered the agricultural waste. The sown areas of these crops are huge. All this was the reason for choosing the aboveground part of potatoes and carrots as objects of study in order to obtain a sufficient amount of biologically active substances. Lipids were extracted from potato and carrottops by hexane extraction, washed, and the unsaponifiable substancesweresplit by column chromatography on silica gel. The fraction composition was determined by physicochemical methods. The results of the experimental study showed that potato and carrot tops contain a significant amount of biologically active components, among which triterpene compounds present a particular interest. Triterpene compounds have properties that can help to fight against oncology and viral diseases: prevent inflammation, inhibit the active division of cells and the growth of pathogenic neoplasms, activate programmed cell death, which makes it possible to recommend the aboveground part of potatoes and carrots as a cheap source of biologically active substances for the pharmaceutical and perfumery industry.
