PREPARATION AND ANALYSIS OF THE NMR SPECTRA OF THE PHARMACEUTICAL SUBSTANCE«OOSE-11,12,13»

Objective: The main issue of this work is obtained, to researching of supramolecular complexes of 20-hydroxyecdysone (20 E) with γ-cyclodextrins (CD).Methods: The foundation of substance phytoecdysteroid 20 E was isolated from an ethanol extract plant Otites orae-syvaschicae Klok A method of the development of pharmaceutical substances was used during complexed organic relationship in the way of intense mechanical 20 E with α-, β- or γ-СD. The complexation of 20 E with α-, β-, and γ-СD was studied by nuclear magnetic resonance (NMR) method of spectrResults: In the study of the integrated intensities molecules signals steroid guest and host CD complex stoichiometric ratio 1:1 was prformation of clathrates was established after A and B nuclei ecdysterone had been arranged in the internal cavity of CD.Сonclusion: Supramolecular complexes of 20 E with α-, β-, and γ-СD were received during made works. The objects of research were analdescribed with the help of NMR spectroscopy. The developed technology will be the main device for operating and identification of pharmaceuticalsubstance OOSE-11, -12, and -13.Keywords: Substance Otites orae-syvaschicae Klok-11, -12, -13, 20-hydroxyecdysone, α-, β-, γ-cyclodextrins inclusion complex nuclear resonance spectroscopy
