Abstract

3'-epi-19-Norafraside, a 19-norcardenolide glycoside with dual linkages between a cardenolide and 4, 6-dideoxy-galactos-2-ulose, and 12β-hydroxycoroglausigenin were newly isolated from the stems of Asclepias curassavica, along with known glycosides and free cardenolides. The structures were determined by spectral and chemical methods.
