Аннотация:A plant Hoodia Gordonii is nowadays regarded as a source of biologically active compounds of natural origin with appetite-suppressant effect. Interdependency of the biological activity of the extracts with the presence of a steroid-based compound of the pregnene series was postulated, and structure of few compounds was elucidated by a variety of techniques. Here we present results of detailed NMR study of major component of the alcohol extracts from Hoodia Gordonii. The structure was elucidated using the whole set of appropriate 1D and 2D NMR techniques: (3β,20S)-20-{[6-O-(6-O-D-glycero-hexopyranosyl-β-D-glycero-hexopyranosyl)-β-D-gly-cero-hexopyranosyl]oxy}-14-hydroxypregn-5-en-3-yl 2,6-dideoxy-4-O-{6-deoxy-2-O-methyl-4-O-[(2E)-2-methyl-2-butenoyl]-β-L-erythro-hexopyranosyl}-3-O-methyl-β-L-erythro-hexopyranoside.
