Guided by in vitro immunological tests, three immunomodulating steroidal glycosides, stemucronatosides A (1), B (2), and C (3), were isolated from the roots of Stephanotis mucronata. On the basis of chemical evidence and extensive spectroscopic methods including 1D and 2D NMR, their structures were determined as 12-O-deacetylmetaplexigenin 3-[O-6-deoxy-3-O-methyl-β-D-allopyranosyl-(1 → 4)-O-β-D-cymaropyranosyl-(1 → 4)-β-D-cymaropyranoside], 12-O-deacetylmetaplexigenin 3-[O-β-D-thevetopyranosyl-(1 → 4)-O-β-D-cymaropyranosyl-(1 → 4)-β-D-cymaropyranoside], and metaplexigenin 3-[O-β-D-glucopyranosyl-(1 → 4)-O-6-de-oxy-3-O-methyl- β-D-allopyranosyl-(1 → 4)-O-β-D-cymaropyranosyl-(1 → 4)-β-D-cymaropyranoside], respectively. These compounds showed immunomodulating activities in vitro.

As part of our ongoing effort to explore the chemical diversity of plants of the United States Midwest region, the isolation and identification of 13 pregnane glycosides named verticillosides A-M from Asclepias verticillata L. are reported. The structures of these compounds were elucidated by various spectroscopic techniques, including 1D and 2D NMR, IR, UV, and HRMS. The cytotoxicity of the isolates was evaluated against paired breast cell lines Hs578T (cancer) and Hs578Bst (normal), however, no significant growth inhibition was observed.

, p. 485 - 498 (2007/10/03)
The aerial part of Asclepias incarnata afforded 34 pregnane glycosides. These were confirmed to have lineolon, isolineolon, ikemagenin, 12-O- nicotinoyllineolon, deacylmetaplexigenin, metaplexigenin, rostratamine, 12-O- acetyllineolon, 15β-hydroxylineolon
