      The frustrated reviewer - recurrant failures in manuscripts describing validation of quantitative TLC/HPTLC procedures for analysis of pharmaceuticals
      K. FERENCZI-FODOR, B. RENGER*, Z. VÉGH (*Vetter Pharma-Fertigung GmbH & Co. KG, Schuetzenstrasse 87, 88212 Ravensburg, Germany; bernd.renger@vetter-pharma.com)

      J. Planar Chromatogr. 23, 173-179 (2010). Many manuscripts and already published articles on analytical procedures to be used in pharmaceutical quality control are characterized by several typical methodological failures and misconceptions. The autors present a collection of typical failures, misconceptions, and misleading data from articles published over the last two years in seven well-known chromatographic publications and provide at the same time a list of references describing optimum approaches to validation of specific TLC/HPTLC procedures. In particular, method specificity, linearity, accuracy, and precision very often are not determined properly and in accordance with best practise.

      Phytochemical screening and evaluation by TLC and UV spectrophotometer of polyherbal tablets
      S. DWIVEDI*, J. BORKAR, A. SAOJI, P. YEOLE (*Institute of Pharmaceutical Education and Research, Wardha, Maharashtra, India)

      Abstract No. C-495, 61st IPC (2009). Screening of different phytoconstituents in a polyherbal tablet formulation. TLC of n-hexane, chloroform and methanol extracts of the tablets on silica gel with n-hexane - ethyl acetate 7:3; chloroform-methanol 9:1, and chloroform - glacial acetic acid - methanol - water 8:40:15:10. Evaluation under UV 254 nm as well as under UV 366 nm after spraying with different reagents: 20 % sulfuric acid, aniline-hydrogen phthalate reagent, anisaldehyde-sulfuric acid reagent, and vanillin-sulfuric acid reagent for the detection of piperine and andrographide, the active constituents present in formulations like Tefroliv Forte tablets. Other constituents (tannins etc) were analyzed by UV spectrophotometry.

With vancomycin as mobile phase additive, resolution of the enantiomers of metoprolol, propanolol, and labetalol was achieved using acetonitrile - methanol - 0.56 mM aqueous vancomycin (pH 5.5) 15:1:2, and acetonitrile - methanol - 0.56 mM aqueous vancomycin (pH 5.5) - dichloromethane 18:2:3:2, respectively. Chromatograms were developed in glass chambers previously equilibrated with the mobile phase at 16 +/- 2 °C for 10-15 min. Detection by exposure to iodine vapor. The detection limits were 1.3, 1.2, 1.5. and 1.4 µg for each enantiomer of atenolol, metoprolol, propanolol, and labetalol, respectively.
