Abstract The two major steroidal saponins from the roots of Asparagus racemosus were isolated by RP-HPLC and their structure determined by extensive NMR studies. Their structures did not match those reported previously for shatavarins. I and IV and were found to be 3-O-{[beta-D-glueopyranosy](1 -> 2)][alpha-L-rhamnopyranosyl(1 -> 4)]-beta-D-glucopyranosyl}-26-O-(P-D-glu(opyranosyl)-(25S)5 beta-furostan-3p,22 alpha,26-triol and 3-O-{[beta-D-glueopyranosyl(1 -> 2)][alpha-L-rhamnopyranosyl(1 -> 4)]-beta-D-glucopyrariosyl}-(25S)-5 beta-spirostan-3 beta-ol.
