Popis: Six steroid glycosides, which gave been called lilioglycosides B, C, E, F, H, and I have been isolated from fresh bulbs ofLilium regale Wills. The structure of each compound has been determined by methods of physicochemical analysis. This is the first time that lilioglycosides B, C, H, and I, have been described; they are, respectively: (25S)-spirost-5-ene-3β,27-diol3-O-β-D-glucopyranoside; (25R)-spirost-5-ene-3β,27-diol3-O-β-D-glucopyranoside27-(3-hydroxy-3-methylglutarate); (25S)-spirost-5-ene-3β,27-diol3-O-{[O-α-L-rhamnopyranosyl-(1→2)],[O-β-D-glucopyranosyl-(1→3)]-β-D-glucopyranoside}; and (25S)-spirost-5-ene-3β,27-diol 3-O-{[O-α-L-rhamnopyranosyl-(1→2)],[O-β-D-glucopyranosyl-(1→3)]-O-β-D-glucopyranoside} 27-[(S)-3-hydroxy-3-methylglutarate].
