Oximes and nitriles of cardenolides

Chemistry of Natural Compounds, 1983
The influence of the oximation of cardenolides and the production of 10-cyanocardenolides on their biological activity has been studied. The prefered conformation of strophanthidin 19-aldoxime has been established; it has chelate fragment as the result of the orientation in the same direction of the nitrogen atom of the oxime group and the hydroxy ...

Spectrophotometric determination of cardenolides

Pharmaceutical Chemistry Journal, 1967
The molar extinctions of strophanthidin glycosides have been determined, and on the basis of these results a physicochemical method for determining glycosides has been developed.

Cardenolides of Erysimum suffruticosum

Chemistry of Natural Compounds, 1974
Seven cardenolides have been isolated from the seeds ofErysium suffruticosum Spreng.: digitoxigenin, strophanthidin, erysimin, desglucocheirotoxin, desglucoerycordin, canescein, and a new glycoside which we have called bipindogulomethyloside. The latter is bipindogenin 3β-O-β-D-gulomethyloside.
