Steroidal glycosides from the roots of Asclepias curassavica.
Twenty-six new acylated-oxypregnane glycosides were obtained along with three known cardenolide glycosides from the roots of Asclepias curassavica (Asclepiadaceae). The new compounds were confirmed to contain 12-O-benzoylsarcostin, 12-O-benzoyldeacylmetaplexigenin, kidjolanin, and 12-O-benzoyltayloron, and one new acylated-oxypregnane, 12-O-(E)-cinnamoyltayloron, as their aglycones, using both ...

متن کاملBiochemical analysis of a papain-like protease isolated from the latex of Asclepias curassavica L.
Most of the species belonging to Asclepiadaceae family usually secrete an endogenous milk-like fluid in a network of laticifer cells in which sub-cellular organelles intensively synthesize proteins and secondary metabolites. A new papain-like endopeptidase (asclepain c-II) has been isolated and characterized from the latex extracted from petioles of Asclepias curassavica L. (Asclepiadaceae). As...
متن کاملCardenolide and oxypregnane glycosides from the root of Asclepias incarnata L.
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-benzoyl...
متن کاملPhytochemical Screening and Antibacterial Studies on Leaf and Root Extracts of Asclepias Curassavica (L)
Asclepias curassavica like most of the medicinal plants has highest significance for its valuable secondary metabolites (glycosides and saponins). The clones produced thereof hence need to maintain their absolute genetic stability so that no unwanted variation in secondary metabolite yield can occur. Plant extracts that inhibit the growth of pathogenic microorganisms without harming the host ma...
