      Stability indicating HPTLC determination of oxcarbazepine in tablets
      G. SUBRAMANIAN, CH. SRIDEVI NAIDU, Gautam MISHRA, Varadaraj BHAT, N. UDUPA* (*College of Pharmacy, Manipal, Karnataka, India)

      56th IPC 2004, Abstract No. GP-47. Stability indicating HPTLC determination of oxcarbazepine in tablet dosage form on silica gel with toluene - methanol 4:1. The Rf value of oxcarbazepine was 0.17. Quantitative determination by scanning at 255 nm. The compound was subjected to acid and alkali hydrolysis, oxidation, dry heat, and photo degradation. All degraded products were well resolved from the pure drug. The method was validated for accuracy, precision, linearity, robustness, and recovery.

      Simplified and rapid method for extraction of ergosterol from natural samples and detection with quantitative and semi-quantitative methods using thin-layer chromatography
      T. LARSEN*, J. AXELSEN, H. WEBER RAVN (*Department of Terrestrial Ecology, National Environmental Research Institute, Vejlsøvej 25, 8600, Silkeborg, Denmark)

      J. Chromatogr. A 1026 (1-2), 301-304 (2004) A new and simplified method for extraction of ergosterol (ergosta-5,7,22-trien-3beta-ol) from fungi in soil and litter was developed using pre-soaking extraction and paraffin oil for recovery. Recoveries of ergosterol were in the range of 94-100 % depending on the solvent to oil ratio. Extraction efficiencies equal to heat-assisted extraction treatments were obtained with pre-soaking extraction. Ergosterol was detected by TLC. Detection by fluorescence measurement, quantification limit was 8 ng. Using visual evaluation of images of TLC plates photographed in UV-light the quantification limit was 16 ng.
