Asparosides A and B, two new steroidal saponins from Asparagus meioclados

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 - f -arabinopyranosyl-(5 g ,25s)-spirostan-3 g ,23 f -diol-3- O -[ g - d -xylopyranosyl(1 M 4)]- g - d -glucopyranoside and 26- O - g -glucopyranosyl-5 g -furost-20(22)-ene-3 g ,26-diol-3- O -[ g - d -xylopyranosyl(1 M 4)]- g - d -glucopyranoside, respectively.
