From the roots with rhizomes of the plantRhaponticum carthamoides Willd) Iljin Compositae), in addition to integristerone A, ecdysterone, polypodin B, 2-deoxyecdysterone, and 24(28)-dehydromakisterone A, we have isolated the new compounds ecdysteron3–2,3-monoacetonide (I), ecdysterone 20,22-monoacetonide (II)) and rhapisterone (III): I — C30H48O7, mp 232–233° (ethyl acetate-methanol) [α] D 20 +56.4±2° (c 0.0; methanol); II — C30H48O7, mp 227–229° (ethyl acetate-methanol), [α] D 20 +60.1±2° (c 1.3; methanol); III — C29H48O7, mp, 241–242° (ethyl acetate-methanol), [α] D 20 +30±2° (c 0.1; dioxane). The structure of (III) was established on the basis of spectral characteristics as 2β, 3β, 14α, 20R, 22R, 23ζ-5β-stigmast-7-en-6-one. Details of the PMR, mass, and IR spectra of all the compounds and of the CD of rhapisterone are given.
