Abstract

Eight new steroidal glycosides, dresiosides were isolated from the stems of Dregea sinensis var. corrugate and their structures were deduced on the basis of chemical and spectral evidence. The sugar units of dresiosides were determined as deoxysugars after hydrolysis and isolation from natural glycosides. The absolute configurations of deoxysugars were determined as D on the basis of their optical rotation values in comparison with appropriate standards.
