Abstract:

A simple and sensitive method for the separation and determination of isoproterenol from other doping drugs has been developed on thin layers of bismuth silicate, a synthetic inorganic ion exchanger as adsorbent in thin layer chromatography (TLC). A mixture of methanol and 0.1 mol/L formic acid (3:7, v/v) was employed as the mobile phase. The development time was 32 min. The quantitative measurement were performed with a Camag TLC Scanner-3 at wavelength (λ) of 410 nm. The isoproterenol recovery in this procedure was 98.9%. The linear correlation coefficient was greater than 0.9871 and the relative standard deviation (RSD) was less than 0.94. The limit of detection (LOD) and limit of quantification (LOQ) were 7.7×10-7mol/L and 3.85 ×10-6mol/L, respectively. This method has been applied in the determination of isoproterenol in dosage forms and in biological fluids.

Key words: densitometry, high performance thin layer chromatography (HPTLC), inorganic ion-exchanger
