Subalpinosid (S1), ein bisher unbekanntes Oleandrigeninglykosid und weitere Cardenolide aus Digitalis subalpina var. subalpinaSubalpinoside (S1), an Unknown Oleandrigenin Glycoside and Other Cardenol from Digitalis subalpina var. subalpina
05 January 2007 (online)
From the leaves of Digitalis subalpina Br.-Bl. var. subalpina an oleandrigenin glycoside was isolated as the main cardiotonic compound besides some known glycosides such as evatromonoside, lanatoside A and B, gitoroside, and others. The structure of this compound was elucidated by spectroscopic methods (1H-, 13C-, 2D-NMR spectroscopy) as gluco-oleandrigenin digitoxoside. This is the first report of the occurrence of oleandrigenin derivatives in a Digitalis species.
