Prospects for use of extracts from the Hibiscus rosa-sinensis and extracts from medicinal plants for the production of drinks

In order to enrich drinks with biologically active substances from the flowers of hibiscus rose sinensis and medicinal plants, with flavonoids in particular, we conducted research their aqueous extracts. On the basis of the aqueous extract obtained, compositions for enrichment of functional purpose drinks have been developed. The chemical composition of hibiscus rose sinensis and the antioxidant activity of the developed compositions has been examined. This article defines the polyuronide content and the degree of esterification of pectin in the flower of hibiscus rose sinensis and in the medicinal plants in combination with the flowers of hibiscus rose sinensis. We examined the quantitative and qualitative composition of free amino acids in the fruits of rosa canina and in the flowers of hibiscus rose sinensis. It was found that depending on the features of the species, 17 amino acids, 7 of which indispensable, are present in the composition of the free amino asids.
