Abstract

Two new spirostanol saponins, named anemarsaponin F (2b) and G (4b), along with six known spirostanol saponins were obtained from the rhizomes of Anemarrhena asphodeloides Bunge. On the basis of spectral analyses and chemical evidence, the structures of 2b and 4b were established as neogitogenin 3-O-β-glucopyranosyl-(1→2)[β-xylopyranosyl-(1→3)]-β-glucopyranosyl (1→4)-β-galactopyranoside) and lilagenin 3-O-β-glucopyranosyl-(1→2)-[β-xylopyranosyl-(1→3)]-β-glucopyranosyl-(1→4)-β-galactopyranoside, respectively.
