      P.S. NAYAK*, S.D. UPADHYAYA, A. UPADHYAYA (*Department of Crop and Herbal Physiology, College of Agriculture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur M. P. 482004 India; preetisagarnayak@rediffmail.com)

      J. Planar Chromatogr. 22, 197-200 (2009). HPTLC of whithaferin A on silica gel with toluene - ethyl acetate - formic acid 5:5:1 in a twin trough chamber saturated for 20 min at 25 +/- 2 °C and 50 +/- 5 % relative humidity. Detection under UV light and by dipping into freshly prepared p-anisaldehyde reagent, followed by heating at 110 °C for 10 min. Quantitative determination by absorbance measurement at 200 nm. The limit of detection and quantification was 100 and 800 ng/zone, respectively. The high sample throughput is useful for routine analysis of the preparation in industrial quality control and regulatory laboratories.

      J. Planar Chromatogr. 21, 289-294 (2008). HPTLC of quetiapine on silica gel with hexane - dioxane - propylamine 5:45:2 and on RP-8 with tetrahydrofuran - phosphate buffer (pH 9.0) 1:1 in horizontal chambers. Quantitative determination by absorbance measurement at 243 nm and by videodensitometry at 254 nm. The precision and accuracy of the four methods were fully comparable and no significant differences were observed.

      Speciation of chromium by high-performance thin-layer chromatography with direct determination by laser ablation inductively coupled plasma mass spectrometry
      J.P. LAFLEUR, E.D. SALIN* (*Department of Chemistry, McGill University, 801 Sherbrooke Street W. Montreal, Canada H3A 2K6; eric.salin@mcgill.ca)

      Anal. Chem. 80, 6821-6823 (2008). HPTLC of Cr3+ and Cr 6+ on silica gel in a saturated chamber with distilled deionized water and Triton-X-100 in concentrations between 0.001 and 0.1%, which is around the critical micelle concentration. Separation was achieved in seconds over 1 cm. Laser ablation was used to volatilize the chromium species directly from the chromatographic material prior to ICP-MS detection. The reliability of calibration was satisfying with precisions between 3 - 30 % and detection limits in the low ng-range. Silicium, which is present in the silica gel plate, was discussed as suitable internal standard.

      Development of HPTLC method for quantification of gallic acid from the fruits of Phyllanthus emblica L
      N. MANJU*, A. BINDU, N. ALEYKUTTY, J. SAJAN (*Department of Pharmaceutical Sciences, Cheruvandoor Campus, Ettumanoor, Kottayam, Kerala, India)

      60th Indian Pharmaceutical Congress PG-265 (2008). HPTLC of gallic acid in the ethyl acetate fraction of fruits of Phyllanthus emblica on silica gel with toluene - ethyl acetate - formic acid - methanol 30:30:8:2. Detection and quantitative determination of gallic acid by absorbance measurement at 280 nm. The proposed HPTLC method provided a good resolution of gallic acid from other constituents present in the ethyl acetate fraction of fruits of Phyllanthus emblica and can be used for the quantification of gallic acid.

      Abstract No. F-272, 61st IPC (2009). HPTLC of wedelolactone on silica gel with toluene - ethyl acetate 9:1. Quantitative determination by fluorescence measurement at 366 nm. The method was linear in the range of 500-8000 ng/mL. Recovery was in the range of 100.2-101.0 %. The plant material was extracted using percolation, maceration, hot solvent extraction, supercritical fluid extraction, microwave assisted extraction, ultra sonication, and an orbital shaker. Quantification of wedelolactone in the extracts showed highest levels for Soxhlet extraction and lowest levels for supercritical fluid extraction.
