Аннотация

In the present work, the determination of chemical structure of the novel cycloartane glycoside,
cyclolehmanoside A is given. Determination of chemical structure was carried out by using of chemical reaction
(acidic hydrolysis) and spectral methods (1D and 2D NMR spectroscopy). Novel cycloartane glycoside,
cyclolehmanoside A was isolated from aerial parts of Astragalus Lehmannianus Bunge (Leguminosae) by column
chromatography on silica, and its chemical structure was established as 3-О-β-D-xylopyranoside, 6,16-di-О-β-Dglucopyranoside-24S-cycloartane-3β,6α,16β,24,25-pentaol.
