Three new spirostanol glycosides from .

An ongoing chemical investigation on -BuOH extract of roots and rhizomes of afforded three new spirostanol glycosides (-). Their structures were elucidated by extensive analysis of 1 D, 2 D NMR spectra, together with IR and MS methods and acid hydrolysis. This is the first report of the isolation of spirostanol glycoside with xylose at C-24 of the aglycone in .
