Pregnane Glycosides from Caralluma adscendens var. fimbriata

CHEMISTRY & BIODIVERSITY, Issue 2 2008
Olaf Kunert
Abstract Eleven novel pregnane glycosides, 2,7 and 9,13, of which four, i.e., 10,13, comprised a new pregnane-type genin exhibiting a hydroxymethylene instead of a Me group at C(19), and the known pregnane glycoside stalagmoside V (8) were isolated from whole plants of Caralluma adscendens var. fimbriata, a native Indian succulent plant. Their structures were elucidated by extensive 2D-NMR spectroscopic studies. [source]

LC-NMR applied to the characterisation of cardiac glycosides from three micropropagated Isoplexis species

PHYTOCHEMICAL ANALYSIS, Issue 5 2002
Isabel Gavidia
Abstract Species of the genus Isoplexis are of particular interest with respect to the biochemical pathway leading to the cardenolides. It is important to determine whether or not 5,-configured compounds, typically produced by Digitalis species and used in medicine, are present together with their respective ,-isomers in Isoplexis spp. Structure elucidation by LC-NMR of the products isolated from in vitro regenerated Isoplexis canariensis, I. chalcantha and I. isabelliana was carried out, and similarities were observed among the products of the three species, including the presence of digitoxigenin-type cardenolides in I. canariensis and xysmalogenin and canarigenin derivatives in I. chalcantha never previously reported in these species. Pregnane glycosides not found until now either in Isoplexis or Digitalis were also detected. Copyright © 2002 John Wiley & Sons, Ltd. [source]
