Abstract
As the continuous scientific research, seven new 1-oxygenated cholestane glycosides named osaundersiosides 1 A − 1 G were isolated from an EtOH extract of the bulbs of Ornithogalum saundersiae. Their structures were deduced by means of spectroscopic data, chemical evidence and the results of hydrolytic cleavage. The cytotoxicity and anti-inflammatory effects of osaundersiosides 1 A − 1 G were evaluated, but none of them displayed significant activities.
