      Stability-indicating methods for the determination of linezolid in the presence of its alkaline-induced degradation products
      L.I. BEBAWY (National Organization for Drug Control and Research, 6 Hussen Kamal el Deen, Ben-el-sariat, Dokki, Giza 12311, Egypt )

      Talanta 60 (5), 945-953 (2003). TLC of linezolid from its alkaline degradation product on silica gel with isobutanol - ammonia 9:1. Quantitative determination by densitometric measurement at 244 nm. The proposed method and two other methods (based on spectrophotometry) were successfully applied to the determination of the drug in bulk powder, in laboratory prepared mixtures with its degradation product and in commercial tablets.

      Comparative evaluation of precoated silica gel plates for preparative layer chromatography
      A. N. CAMPBELL*, J. SHERMA (*Dept. of Chem., Lafayette Col., Easton, PA 18042, USA)

      Acta Chrom. 13, 102-108 (2003). Five commercial preparative layer chromatography plates precoated with silica gel of 1 mm thickness were compared on the basis of theoretical plate number and resolution by developing a test dye mixture (1.0 - 5.0 µg per zone) with ethyl acetate – methanol – water 4:1:1. Best results were obtained with the Mallinckrodt–Baker layer with 4.5 - 5.5 µm spherical particles. With one exception the efficiency and resolution of the other layers correlated with their particle size.

      TP-HPTLC and HPTLC methods for the estimation of carvedilol in bulk drug and pharmaceutical formulations
      L. J. PATEL*, B. N. SUHAGIA, P. B. SHAH, R. R. SHAH (*Shri B. M. Shah College of Pharmacy, Modasa 383315, India)

      Indian J. Pharm. Sci. 68 (6), 790-793 (2007). HPTLC of carvedilol in bulk drug and pharmaceutical formulations, on silica gel with ethyl acetate - toluene - methanol 2:8:7. Quantitative absorbance measurement at 242 nm. The hRf value of carvedilol was 65. The method was found to be linear over the concentration range of 50-300 ng/spot with recovery of 98.3-101.1%.The method was validated for accuracy and precision. Comparison with an HPLC method showed the HPTLC method to be advantageous regarding sample throughput.

      Part II. Connection with RP18 and silica plates. J. Chromatogr. Sci. 46 (4), 291-297 (2008). Optimization of the one-dimensional TLC of alkaloid standards on cyano phase, RP-18W, and silica gel with various eluents containing silanol blockers (besides diluent and modifier), such as diethyl amine or ammonia. Separation of alkaloid mixtures with the most selective system (e.g. methanol - water 4:1 in the first direction and methanol - acetone - diisopropylether - diethylamine 15:15:69:1 in the second direction) with an adsorbent gradient method. Alkaloids or plant extracts of Chelidonium majus, Fumaria officinalis, or Glaucium flavum were chromatographed in the first system, the plates were connected with the plate pre-coated with various adsorbents, and partly separated fractions were transferred to the second layer and developed in a second system. Cyano - silica - RP-18W and cyano - silica - silica were used as the connected layers. The alkaloids were identified based on the Rf values of standards, and by comparison of UV spectra obtained by densitometry with a diode array detector.
