Asparosides A (1) and B (2), two new saponins, were isolated from the roots of Asparagus meioclados. On the basis of chemical and spectroscopic evidence, their structures were elucidated as 23-O-alpha-arabinopyranosyl-(5beta,25s)-spirostan-3beta,23alpha-diol-3-O-[beta-D-xylopyranosyl(1-->4)]-beta-D-glucopyranoside and 26-O-beta-glucopyranosyl-5beta-furost-20(22)-ene-3beta,26-diol-3-O-[beta-D-xylopyranosyl(1-->4)]-beta-D-glucopyranoside, respectively.
