Relevance. Astilbe chinensis has clinical efficacy against many diseases, making this plant a potential natural source for treating diabetes and obesity with a mild, non-aggressive effect. Overall, the study of the biological properties of A. chinensis leaves is currently in its infancy.Aim. In this study, the anti-amylase and anti-lipase potential of aqueous extract of Astilbe chinensis leaves was investigated as an important source of natural complex substances with therapeutic potential. Methods. The total content of phenolic compounds was determined by the Folin-Ciocalteu method and flavonoids by the colorimetric method according to the complexation reaction with aluminum chloride. The effects of aqueous/tea extracts of A. chinensis leaves on pancreatic amylase and lipase were studied via in vitro models in comparison with acarbose and orlistat, respectively. For these tests, the artificial substrates 1,2-O-dilauryl-rac-glycero-3-glutaric acid ester (6-methylresorufin) and 2-chloro-4-nitrophenol oligosaccharide were used.Results. The study of the effect of aqueous extract of A. chinensis leaves on pancreatic amylase and lipase showed a comparable inhibitory effect of 18% on both enzymes.
