摘要：

A spectrophotometric method for the determination of some tetracyclines is described. The suggested method is based on the reaction of the drug with sodium tungstate at pH 6 to form a yellow complex which can be determined spectrophotometrically. The complexes show absorption maxima at 380, 3385 and 390 nm for oxytetracycline hydrochloride(OTCH), doxycycline hydrochloride(DCH) and chlortetracycline hydrochloride(CTCH), respectively. These drugs can be determined either in pure form or in pharmaceutical preparations.
