  From the seeds of Asclepias curassavica, two cardenolides and twelve glycosides were obtained. Among these, four compounds were determined to be 16α-hydroxycalotropagenin, 16α-hydroxycalotropin and its 3'-O-glucoside and 3'-O-gentiobioside. Normally linked triosides of corotoxigenin, coroglaucigenin and 12β-hydroxycoroglaucigenin were characterized as cellobiosyl-allomethylosides.

  Twenty-nine new oxypregnane glycosides were obtained along with two known cardenolides, frugoside and gofruside, and three known 12-O-acylated pregnane glycosides from the roots of Asclepias incarnata L. (Asclepiadaceae). By detailed studies of the 1H- and 13C-NMR spectra, the structures were determined to be tri- to penta glycosides of isolineolon, 12-O-acetyllineolon, ikemagenin, 12-O-benzoylisolineolon, and two new 12-O-acylated pregnanes.
