Cardenolide 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 کاملAcylated-oxypregnane glycosides from the roots of Asclepias syriaca.
Twenty new pregnane glycosides were obtained from the roots of Asclepias syriaca L. (Asclepiadaceae). These glycosides were confirmed to contain ikemagenin, 12-O-nicotinoyllineolon, 5alpha,6-dihydroikemagenin, and 12-O-tigloylisolineolon, as their aglycones, using both spectroscopic and chemical methods.
متن کاملSteroidal glycosides from the aerial part of Asclepias incarnata L. II.
Thirty new steroidal glycosides were obtained from the aerial part of Asclepias incarnata L. (Asclepiadaceae). These glycosides were confirmed to have lineolon, isolineolon, 12-O-acetyllineolon, 12-O-(Z)-cinnamoyllineolon, metaplexigenin, 15 beta-hydroxylineolon, 15 beta-hydroxyisolineolon, 16 alpha-hydroxyisolineolon, 12-O-tigloyl-16 alpha-hydroxyisolineolon as the aglycone and 2,6-dideoxyhexo...
متن کاملSullivantosides A-F: Pregnane glycosides from Asclepias sullivantii L
Phytochemical investigation of the above-ground biomass of Asclepias sullivantii L. (Asclepiadaceae) afforded six new pregnane glycosides, named sullivantosides A-F (1–6). The structures of 1–6 were elucidated through a variety of spectroscopic and spectrometric techniques (1D and 2D NMR; HRESIMS). To the best of our knowledge, this work represents the first phytochemical study of this species....
متن کاملVerticillosides A–M: Polyoxygenated pregnane glycosides from Asclepias verticillata L
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 is...
