Abstract
Aim:
To study the impurity of the drug testosterone.
Methods:
Chromatography methods were used to separate the chemical constituents. Their structures were determined by NMR and MS spectral analysis.
Results:
Two new epimers were isolated from the mother liquid of the drug.
Conclusion:
These new epimers were identified as 3alpha-ethoxyandrost-4-en-17beta-ol, 3beta-ethoxyandrost-4-en-17beta-ol.
