Gas chromatographic analysis of ditigoxigenin and digoxigenin, the genins of the cardenolide glycosides digitoxin and digoxin, cannot be done without derivatization. However, during the derivatization, side-reactions often present serious problems. A procedure has been found for transforming digitoxigenin and digoxigenin into the corresponding acetates of their epoxygeninic acid methyl esters, which are stable compounds and suitable for gas chromatographic analysis.
