Article abstract of DOI:10.1016/0031-9422(89)80212-2

Five steroidal glycosides were isolated from the fresh caudex of Yucca gloriosa together with YG-1 and Ps-1 previously obtained from flowers and the structures of these glycosides were established to be smilagenin 3-O-β-D-glycopyranosyl-(1->2)-β-D-glucopyranoside (Ys-I), 3-O-β-D-glucopyranosyl-(1->2)-β-D-galactopyranoside (YS-II), 3-O-β-D-glucopyranosyl-(1->2)-<β-D-glucopyranosyl-(1->3)>-β-D-glucopyranoside (YS-III), 3-O-β-D-glucopyranosyl-(1->2)-<β-D-glucopyranosyl-(1->3)>-β-D-galactopyranoside (YS-IV) and samogenin 3-O-β-D-glucopyranosyl-(1->2)-β-D-galactopyranoside (YS-V), respectively.Key Word Index - Yucca gloriosa; Agavaceae; steroidal saponins; smilagenin glycosides; samogenin glycoside.
