title: Minor steroidal glycosides from the roots of Smilax lebrunii.
abstract: Three new minor steroidal saponins, (25R) 5 alpha-spirostan-3 beta-o1-6-one-3-O-[alpha-L-arabinopyranosyl(1-4)-beta-D- glucopyranoside, (25S) spirost-5-en-3 beta, 27-diol-3-O-[alpha-L-arabinopyranosyl (1-6)]-beta-D-glucopyranoside, and (25S) spirost-5-en-3 beta, 17 alpha, 27-triol-3-O-[alpha-L-arabinopyranosyl (1-6)]-beta-D-glaucopyranoside, were isolated from the root of Similax lebrunii, in addition to two known steroidal glycosides. Their structures were elucidated on the basis of chemical and spectral methods.
