Investigation of the methanol extract of the roots of Serratula wolffii resulted in an ecdysone-related compound, 2beta,3beta,20R,22R,25-pentahydroxy-5beta-cholest-6,8(14)-dien (1), a new ecdysteroid, 24-methylene-shidasterone (2), the known compound stachysterone B (3) and its 14,15-alpha-epoxide (4), a novel natural product. The structures of compounds 1-4 were established by spectral analysis ((1)H NMR, (13)C NMR, COSY, NOESY, HMQC, HMQC-TOCSY and HMBC).
