Journal of Pharmacy and Pharmacology, 1977 AbstractPredictable hydrolysis of [3H]digoxin-12α occurred in vitro with incubation in HCl or gastric juice. Hydrolysis varied with pH, time, temperature and agitation. Digoxin, the bis- and mono-digitoxosides of digoxigenin and digoxigenin were separated by silica gel thin-layer chromatography using chloroform-ethyl acetate-glacial acetic acid (25:25 ...
