      Coupled layers and multi-dimensionality in planar separations
      SZ. NYIREDY, B. SZABADY, (Res. Inst. for Med. Plants, Lupaszigeti ut 4, 2011 Budapest, Hungary)

      Sz. Nyiredy, A. Kakuk (eds.): Planar Chromatography 2000, Lillafüred, Hungary, 24-26 June 2000, Res. Inst. for Med. Plants, p. 121-132. A variety of modes of multidimensional separation in TLC are shown. Two-dimensional or multidimensional planar chromatography, two-dimensional development on bilayers, coupled layers with stationary phases of decreasing polarity and combination of multidimensional planar chromatographic methods are demonstrated. The greatest strength of multidimensional separation is that compounds are distributed widely over two-dimensional space of high zone capacity. A zone capacity of ca. 1500 could be achieved. Image analyzers might improve quantitation in future.

      Future of OPLC
      E. TYIHAK, E. MINCSOVICS, (Plant Protection Institute, Hungarian Acad. of Sciences, P.O. Box 102, 1525 Budapest, and OPLC-NIT Co. Ltd., Andor ut 60, 1119 Budapest, Hungary)

      Sz. Nyiredy, A. Kakuk (eds.): Planar Chromatography 2000, Lillafüred, Hungary, 24-26 June 2000, Res. Inst. for Med. Plants, p. 37-44. OPLC provides efficient separation of different substance groups and the attractive semi-preparative isolation of substances of different type. Characteristics of mobile phase flow and efficiency as well as potentialities of the off-line and on-line mode are shown.

      Chromatographic methods in pharmaceutical purity testing
      K. FERENCZI-FODOR, B. BAGOCSI, D. FABIAN, E. GÜRTLER, Z. VEGH, (Gedeon Richter Ltd., P.O.Box 27, 1475 Budapest 10, Hungary)

      Sz. Nyiredy, A. Kakuk (eds.): Planar Chromatography 2000, Lillafüred, Hungary, 24-26 June 2000, Res. Inst. for Med. Plants, p. 19-25. OPLC of ethinyl estradiole on silica gel with cyclohexane - ethyl acetate - chloroform 3:1:1. Detection by spraying with sulfuric acid and visual evaluation at 366 nm. The method is compared with the Official British and European Pharmacopoeia monographs. Only with the OPLC method it was possible to separate all impurities, i.e. 6-hydroxy derivatives (both isomers), the oxo-derivatives (6-oxo- and 16-oxo-), the 9(11)-dehydro and the 17-epi-derivatives from the estrone and estradiol. The HPLC method of the 3rd European Pharmacopoeia has to be changed slightly in order to analyze all impurities. The British Pharmacopoeia TLC method was not suitable because of its poor selectivity. Both OPLC and HPLC are suitable for purity testing. The OPLC method was preferred for process-validation because it shows a short analysis time and low eluent consumption (tenfold less than HPLC). The HPLC method was used for critical batches due to its better precision (3,5% RSD).

      Centrifugal thin-layer chromatography of alkaloids from vegetable sources using an aluminium oxide layer
      M. FERRARI, L. VEROTTA, (Dipart. Chim. Organica e Industr., Univ. degli Studi di Milano, Via G. Venezian 21, I-20133 Milan)

      J. Chromatogr. 437, 328-332 (1988). Preparative separation of closely related alkaloids from Papaver and Fumaria species on aluminium oxide by centrifugal TLC with cyclohexane - toluene - diethylamine 320:80:1, 160:40:1 or 160:40:3. Flow-rate 0.5-1.5 mL/min. The rotors (1 mm layer thickness) were prepared from a mixture of 40 g basic aluminium oxide, 10g calcium sulfate hemihydrate and 110 mL water.

      ROTACHROM®
      S. NYIREDY, L .BOTZ, O. STICHER*, (*Dep. of Pharm., Swiss Federal Inst. of Techn. (ETH) Zürich, CH-8092 Zürich, Switzerland)

      J. Planar Chromatogr. 2, 53-61 (1989). Construction of the new instrument with the principle of five rotation planar chromatographic methods. The efficiency of the RPC methods demonstrated with the separation of saponin glycosides from Panax ginseng and some furocoumarin isomers from Pastinaca sativa. For preparative separation, an extract from Peucedanum palustre was chosen.

      Progress in automated multiple development
      C.F. POOLE*, M.T. BELAY, (*Dept. of Chem., Wayne State Univ., Detroit, MI 48202, USA)

      J. Planar Chromatogr. 4, 345-359 (1991). Description of the evolution of automated multiple development from manual multiple development through programmed multiple development and discussion of the general role of solvent strength gradients and solvent selectivity emphasizing their application to AMD. The large number of experimental parameters encountered in method development is recognized as one of the main current weaknesses of AMD. The method has, however, a number of attractive features which will ensure continuing interest in the technique.
