Phytochemical examination of the bulbs of Ornithogalum saundersiae led to the isolation of three new acylated cholestane glycosides. Their structures were elucidated, on the basis of the spectroscopic data and chemical evidences, and by comparing them with those of known compounds, as 3βP,16βP,17α-t...
