title: Photostability studies of ouabain, alpha-acetyldigoxin and digoxin in solid state.
abstract: Ouabain, alpha-acetyldigoxin and digoxin were subjected to irradiation using different light sources in crystalline state and their respective yields of photoproducts were determined densitometrically. alpha-Acetyldigoxin was found to be less stable than digoxin yielding a higher percentage of photoproducts under each light source examined. Ouabain showed photostability under the conditions of investigation.
