Facile separation of sulfonamides from their degradates by liquid--liquid extraction
J Pharm Sci.1978 Oct;67(10):1415-9.PMID: 702292DOI:10.1002/jps.2600671023
Regulation of acidity for protonation of the free N4-amine can provide for the selective liquid--liquid extraction isolation of a sulfonamide from its degradation products. This principle is applied for the stability-indicating determination of sulfacetamide in the presence of sulfanilamide, sulfaquinoxaline in feed, and sulfabromomethazine in dosage forms. In solution, sulfabromomethazine can exhibit photodecomposition to sulfamethazine. The mean relative errors of the these methods and the precision, represented by relative standard deviations, are each typically less than 2%.
Gas-liquid chromatographic determination of sulfamethazine in swine and cattle tissues
J Assoc Off Anal Chem. 1981 Jul;64(4):794-9. PMID: 7275892DOI:
A gas-liquid chromatographic (GLC) method is described for determining sulfonamide residues in animal tissues, with specificity for 7 sulfonamides. Residues are extracted from tissues with acetone-chloroform, fatty substances are removed, and the sulfonamide residue is methylated with diazomethane in acetone-ether to render it amenable to determination by gas-liquid chromatography on an all-glass column suitable for direct on-column injection and a Ni electron-capture detector. Quantitation is achieved by external standardization. The method has a validated limit of sensitivity of 0.10 ppm with the corresponding control values for all tissues being less than 0.01 ppm. Satisfactory recoveries have been obtained for sulfamethazine in swine and cattle tissues. Specificity for sulfamethazine in the presence of sulfathiazole, sulfaquinoxaline, sulfadimethoxine, sulfabromomethazine, sulfaethoxypyridazine, and sulfachloropyrazine is attained by resolution of the respective methyl derivatives on the GLC column.
Sensitive and specific gas-liquid chromatographic-spectrophotometric screening procedure for trace levels of five sulfonamides in liver, kidney, and muscle tissue
J Assoc Off Anal Chem.1978 Sep;61(5):1050-3.PMID: 721719DOI:
Free and conjugated sulfonamides are extracted from edible animal tissue with acetone. Carbohydrate is precipitated and removed, and the acetone is evaporated. The residue is transferred to a separatory funnel with ethyl ether and 1N HCl. The acid layer is drawn off and a portion of the 1N HCl is screened, using the Bratton-Marshall reaction. If this portion is positive, the remaining portion is buffered to pH 6.5 and extracted with methylene chloride. The residue is methylated with diazomethane and then acylated with pentafluoropropionic anhydride. The resulting derivatives are detected by gas-liquid chromatography, using electron capture (63Ni) detection and a column packed with 3% OV-17 on Gas-Chrom Q. This method has been validated by recovering sulfathiazole, sulfachloropyrazine, sulfamethazine, sulfadimethoxine, and sulfabromomethazine from liver, kidney, and muscle at levels of 0.1, 0.5, and 1.0 ppm. The 5 sulfonamides were recovered in excess of 60%, with an average mean recovery of 81.5% at the 0.1 ppm level, 79.1% at the 0.5 ppm level, and 76.0% at the 1.0 ppm level.
Quantitation of sulfamethazine in pork tissue by thin-layer chromatography
J AOAC Int.1993 Mar-Apr;76(2):335-41.PMID: 8471859DOI:
Our earlier method to detect and quantitate sulfamethazine (SMZ) in milk at the 10 ppb level was modified to quantitate SMZ in pork tissue. Sulfabromomethazine (SBZ) is added to the tissue as an internal standard. SMZ and SBZ are extracted from the tissue into water as the supernatant of a centrifuged, aqueous homogenate and are cleaned up and concentrated by a series of solid-phase extractions. The sulfonamide-containing eluate is then separated on a silica gel thin-layer chromatographic plate. SBZ and SMZ are derivatized with fluorescamine, and their fluorescence is quantitated with a scanning densitometer. The limit of detection was estimated at 0.25 ppb (signal-to-noise ratio, 3:1). The average accuracy over the analysis range (0.54-21.8 ppb [micrograms/kg]) was 95.6% (standard deviation = 29.4%, n = 54).
Quantitative thin layer chromatographic multi-sulfonamide screening procedure
J Assoc Off Anal Chem.1983 Jul;66(4):881-3.PMID: 6885694DOI:
In-situ optical scanning of fluorescamine derivatives on thin layer silica gel plates provides a rapid method for the determination of multiple sulfonamides at levels below 0.1 ppm. Sample preparation is minimal. Homogenized liver or muscle is extracted with ethyl acetate and then back-extracted into 0.2M glycine buffer. After pH adjustment, the extract is washed with hexane and extracted with methylene chloride. The organic phase is evaporated to dryness and reconstituted in methanol. Pre-adsorbent layer silica gel plates are used for chromatography. The method has been applied to residues of sulfamethazine, sulfadimethoxine, sulfathiazole, sulfaquinoxaline, and sulfabromomethazine in cattle, swine, turkey, and duck tissues.
