Eight new steroidal glycosides, tentatively named YS-VI, -VII, -VIII, -IX, -X, -XI, -XII, -XIII were isolated from the caudex of Yucca gloriosa along with P-1, YG-2 and YG-3 previously obtained from flowers.The structures of five of these compounds were elucidated as mexogenin 3-O-β-D-glucopyranosyl-(1->2)-β-D-galactopyranoside (YS-VI), gloriogenin 3-O-β-D-glucopyranosyl-(1->2)-3)>-β-D-glucopyranoside (YS-VII) and 3-O-β-D-glucopyransyl-(1->2)-3)>-β-D-galactopyranoside (YS-VIII), manogenin 3-O-β-lycotetraooside (YS-IX) and 3-O-α-L-rhamnopyranosyl-β-lycotetraoside (YS-X), respectively on the basis of chemical and spectral evidence.
