Abstract
A new pregnane glycoside roylenine (1) was isolated from the CHCl3–EtOH (4:1) extract of Marsdenia roylei. Its structure was established on the basis of spectroscopic studies. The glycoside (1) and its acetylated derivative (6) were evaluated for their antioxidant and antidyslipidemic activities.
