Notizen: Abstract Tetracycline, chlortetracycline and oxytetracycline react with Eu (III) to form complexes which exhibit analytically useful room temperature phosphorescence (RTP). The RTP features of the three complexes are similar and the RTP spectra completely overlap. However, their three phosphorescence decay rates are quite different. These differences are utilized here to analyze the time-resolved RTP data by Kalman filtering. Simultaneous quantification of all the three complexes is demonstrated and a method is proposed for the simultaneous determination of the three tetracyclines in mixtures by RTP optosensing. Analytical errors observed are within ± 5%.

Schlagwort(e): Sulfonamides ; absorption rate constants ; reverse-phase partition chromatography ; Wagner-Sedman extraction theory ; absorption from the small intestine ; logarithmiclogistic correlations

Quelle: Springer Online Journal Archives 1860-2000

Thema: Chemie und Pharmazie

Notizen: Abstract The chromatographic parameters in a reverse-phase partition system and the rat gut in situabsorption rate constants for 18 antibacterial sulfonamides are highly correlated values. The correlation is logarithmic-logistic in nature, being in accordance with the Wagner-Sedman extraction theory for a constant pH value. Parabolic correlations did not satisfactorily fit the experimental data. This behavior, not frequently reported in regard to the intestinal absorption of drugs, is discussed in connection with other apparently contradictory available data.
