title: [Determination of sulfacetamide sodium and sulfanilamide in shao tang ling ointment by high performance liquid chromatography].
abstract: An HPLC method for the determination of sulfacetamide sodium and sulfanilamide in Shao Tang Ling ointment was developed. The chromatographic conditions were: column, Spherisorb C18, mobile phase, methanol-0.25% (V/V)-acetic acid solution (7:93); detector UV-257 nm. The average recoveries were 98.9% (n = 5), RSD = 0.64% for sulfacetamide sodium and 99.3% (n = 5), RSD = 1.58% for sulfanilamide. The analytical method is simple, quick, accurate and reproducible.
