Chemical Composition of Flowers of Yucca elephantipes Cultivated in Georgia

Three sesquiterpene glycosides, i.e., nerolidol derivatives, and steroidal glycosides of the 3-furostanol and 1-spirostanol series, one of which was new and characterized as (25R)-26-O-β-D-Glcp-5α-furostan-3β,22α,26-triol 3-O-β-D-Xylp-(1→3)-[O-β-D-Glcp-(1→3)-O-β-D-Glcp-(1→2)]-O-β-D-Glcp-(1→4)-O-β- D-Galp, were isolated from flowers of Yucca elephantipes Regel cultivated in Georgia. The structures of the glycosides were elucidated using one- and two-dimensional NMR ( 1 H, 13 C, HSQC, HMBC, COSY) and mass spectrometry (ESI-MS).
