摘要：

The differential pulse polarographic determination of Corticosteroids in single-component tablets is described. The active compounds are extracted from the excipients with a solvent with similar lipophilicity as the polarographic solvents, with a yield of about 100%. The corticosteroid esters and alcohols are determined by standard addition methods. The standard deviations range from 0.5 to 2.5% depending on the excipients and on the method of extraction. © 1979.
