2-Deoxyecdysone-3β,14α,22R,25-tetrahydroxy-5β(Н)-cholest-7-ene-6-one has been isolated from Silene wolgensis (Hornem.) Bess. ex. Spreng. of Caryophyllaceae Juss. Family For the first time. The complex formation of phytoecdysteroid with α-, β- and γ-cyclodextrins has been studied by NMR spectroscopy. Based on the change in the chemical shifts of substrate protons and receptors, it has been established that 2-deoxyecdysone interacts with α-, β- and γ-cyclodextrins with the formation of supramolecular inclusion complexes of 1:1 stoichiometric ratio with the entry of ring A of the steroid nucleus of the substrate molecule into the internal cavity of the receptor. Anti-inflammatory activity of the complexes has been studied.
