      Validation of a new planar chromatographic method for quantification of the heterocyclic aromatic amines most frequently found in meat
      Ute JAUTZ, Gertrud MORLOCK* (*Institute of Food Chemistry, University of Hohenheim, Garbenstr. 28, 70599 Stuttgart, Germany, gmorlock@uni-hohenheim.de)

      Anal. Bioanal. Chem. 387, 1083-1093 (2007). A new HPTLC method for trace analysis (low µg/kg range) of the five heterocyclic aromatic amines PhIP (2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine), MeIQx (2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline), 4,8-DiMeIQx (2-amino-3,4,8-trimethylimidazo[4,5-f]quinoxaline), norharmane (9H-pyrido[3,4-b]indole) and harmane (1-methyl-9H-pyrido[3,4-b]indole) in meat samples has been established. HPTLC on LiChrospher silica gel WRF with methanol – chloroform 1:9. Using the ADC2, the plate activity was adjusted to 34 % relative air humidity with MgCl2 x 6H2O for 15 min and, at the same time, chamber saturation with 35 mL aqueous ammonia 28 % – ultrapure water 1:4 was performed for 20 min, followed by alkaline plate preconditioning for 15 min. The development was performed in a fresh chamber. Quantitative determination by absorbance measurement at UV 262 nm and 316 nm, and fluorescence measurement at UV 366/>400 nm. The UV wavelength 316 nm was later substituted by 313/>340 nm for a more selective and sensitive determination of PhIP in the meat matrix. Mass spectrometric analysis was performed in ESI+ mode for confirmation of positive findings. The method was validated according to ICH guidelines. Repeatability was better than 3.3 % (n=14), the intermediate precision (n=6, peak area) was 0.4 % (PhIP), 0.6 % (MeIQx), 0.7 % (4,8-DiMeIQx), 0.9 % (norharmane) and 1.1 % (harmane). Reproducibility of the migration distance was better than 1.3 % (n=6). LODs were 4 ng/band for PhIP, 5 ng/band for MeIQx, 4 ng/band for 4,8-DiMeIQx, and 0.4 ng/band each for norharmane and harmane. LOQs were 6 ng/band for PhIP, 14 ng/band for MeIQx, 11 ng/band for 4,8-DiMeIQx, and 0.8 ng/band each for norharmane and harmane. Selectivity in the meat matrix was proven. Confirmation of the substances found in meat was performed by MS. In the working range RSDs of the calibration functions were between 1.9 and 3.6 %.

      HPTLC METHOD FOR THE ANALYSIS OF MELATONIN IN BULK AND PHARMACEUTICAL FORMULATIONs
      S. Agarwal*, H. Gonsalves, R. Khar (*Dept. of Pharmaceutical Science, Faculty of Pharmacy, Jamia Hamdard University, New Delhi 110062, India, agarwal_sp@yahoo.com)

      Asian J. Chem. 20(4), 2531-2538 (2008). TLC of melatonin on silica gel with toluene - ethyl acetate - formic acid 10:9:1. Quantitative determination by absorbance measurement at 290 nm. The method was linear in the concentration range of 100 to 600 ng/spot. The recovery of the drug from tablets (by standard addition method) was 99.7 %. Statistical analysis proves that the method is repeatable, selective and accurate for the estimation of the drug. Forced degradation studies showed the effect of variations in pH, UV light and high temperature on the stability of melatonin. As the proposed method could effectively separate the drug from its degradation products, it can be employed as a stability indicating method.
