      Stability indicating HPTLC assay method for determination of irbesartan in pharmaceutical formulations 62nd Indian Pharmaceutical Congress Abstract No
      S. KELA*, P. DESAI, C. MODI, P. MEHTA (*Institute of Pharmacy, Nirma University, Ahmedabad 382481, Gujarat, India)

      F-255 (2010). TLC of irbesartan on silica gel with ethyl acetate – toluene – glacial acetic acid 35:15:1. Quantitative determination by absorbance measurement at 240 nm. The method was linear in the range of 200-800 ng/band. The sample was subjected to different stress conditions (acid, alkali, oxidation, thermal & photolytic). The compound was well separated from the different degradation products and could be estimated without any interference from the degradation product. The proposed stability indicating assay method was found suitable for routine quality control.

      62nd Indian Pharmaceutical Congress Abstract No. F-254 (2010). TLC of amlodipine besylate and telmisartan on silica gel with ethyl acetate – methanol – 25 % ammonia – glacial acetic acid 75:15:1:2. The hRf value was 34 and 60 for amlodipine besylate and telmisartan, respectively. Quantitative determination by absorbance measurement at 226 nm.

      Analysis of biodiesel conversion using thin-layer chromatography and nonlinear calibration curves
      S.N. FEDOSOV*, J. BRASK, X. XU (*Dept. Molecular Biology, Aarhus Univ., Science Park, Gustav Wieds Vej 10C, 8000 Aarhus C, Denmark)

      J. Chromatogr. A 1218 (19), 2785-2792 (2011). Examination of the applicability of TLC for the analysis of biodiesel conversion. Biodiesel is a complex mixture which complicates the analytical separation and requires a large set of data for understanding reaction kinetics. A flame ionization detector (FID) and a modified TLC staining procedure were evaluated in comparison with the well-established but time-consuming and expensive GC and HPLC methods. The TLC staining method is suited for quantitative analysis due to no background. Demonstration by using several experimental samples produced by enzymatic conversion of rapeseed oil to biodiesel. It was found that the first reaction step (6 h) resulted in 85–95 % conversion and the second step (after removal of glycerol and water) increased the yield to 97–98 %. All components of the mixtures were separated and quantified. Relation of the biodiesel contents measured by TLC and GC gave the values of 1.03 ± 0.07 (TLC-staining) and 0.95 ± 0.04 (TLC–FID), which indicated the applicability of the TLC methods.
