The application discloses steroidal glycoside compounds, especially spirostanyl glycosides, which have a glycosyl group O-linked to the C-3 hydroxy radical of the steroid and where the moieties at the C-10 and C-11 positions of the steroid are the same or different and are selected from the group consisiting of methylene, hydroxy and carbonyl. These steroid glycosides are useful as hypocholesterolemic agents and anti-atherosclerosis agents.
