  New steroidal glycosides from the rhizome of Anemarrhena asphodeloides

  摘要：

  Two new steroidal saponins, timosaponin X (1) and timosaponin Y (2), and one new pregnane glycoside, timopregnane B (3), were isolated from the rhizomes of Anemarrhena asphodeloides, as well as three known compounds 25S-timosaponin BII (4), protodesgalactotigonin (5), and timosaponin BII-a (6) isolated from this plant for the first time. By the detailed analysis of 1D, 2D NMR, MS spectra, and chemical evidences, the structures of new compounds were elucidated as 26-O-beta-D-glucopyranosyl-(25S)-5 beta-22-methoxy-furost-3 beta, 26-diol 3-O-beta-D-glucopyranosyl( 1 -> 2)-alpha-L-arabinopyranoside (1), 5 beta-pseudo-spirost-3 beta, 15 alpha, 23 alpha-triol 3-O-beta-D-glucopyranosyl-( 1 -> 2)-beta-D-galactopyranoside (2), (5 beta, 17 alpha)-Delta(16(17))-20-one-pregn-2 beta, 3 beta-diol 3-O-beta-D-glucopyranosyl-(1 -> 2)-beta-D-galactopyranoside (3).
