Phytochemical examination of the bulbs of Ornithogalum saundersiae yielded six cholestane rhamnosides, two of which had previously been isolated from the same plant material. However, detailed spectroscopic analysis of the aglycone led us to revise the configuration of the C-11 hydroxyl group of the
A novel 16,23-epoxy-5 beta-cholestane glycoside with potent inhibitory activity on proliferation of human peripheral blood lymphocytes from Ornithogalum saundersiae bulbs.

Phytochemical analyses have been carried out on the fresh bulbs of Ornithogalum thyrsoides with particular attention to the steroidal glycoside constituents, resulting in the isolation of four new spirostanol saponins and seven new cholestane glycosides, together with three known steroidal
Saundersiosides C-H, rearranged cholestane glycosides from the bulbs of Ornithogalum saundersiae and their cytostatic activity on HL-60 cells.
