      Use of Different Salt Solutions in Salting-Out TLC of Co(III) Complexes on Silica Gel
      Vukosava ZIVKOVIC-RADOVANOVIC*, Gordana VUCKOVIC (*Faculty of Chemistry, University of Belgrade, P.O. Box 158, 11001 Belgrade, Serbia)

      Chromatographia 67 (3-4), 259-267 (2008). Investigation of saturated aqueous solutions of 28 different salts used as potential mobile phases for salting-out TLC, on silica gel with a series of four mixed bis-aminocarboxylato cobalt(III) complexes. Confirmation of three alkali metal chlorides, and four alkaline earth metal chlorides, four linear dependences previously established on different adsorbents with (NH4)2SO4 solutions by linear regression analysis of chromatographic data obtained for fifteen mixed aminocarboxylato Co(III) complexes (four series) with solutions of ammonium chloride. With Li+, Mg2+, and Ca2+ chlorides the best separation was achieved.

Quantitative determination by absorbance measurement at 288 nm. The hRf value was 72 and selectivity regarding matrix was given. Linearity was in the range of 0.25 and 7.5 µg/spot. The limits of detection and quantification were 47 and 142 ng/spot, respectively. Recovery was 97.8 %. No significant intra- and interday variation was observed. The method proved to be precise, accurate, and rapid in comparison with a reference HPLC method.

      Validated HPTLC method for identification of Hoodia gordonii
      Valeria WIDMER, E. REICH*, Alison DEBATT (*CAMAG Laboratory, Sonnenmattstrasse 11, 4132 Muttenz, Switzerland; eike.reich@camag.com)

      J. Planar Chromatogr. 21, 21-26 (2008). HPTLC of extracts of Hoodia gordonii with fructose and beta-sitosterol as standards on silica gel with chloroform - methanol - water 70:30:3 in an automatic developing chamber fitted with a twin-trough chamber. The chamber was saturated for 20 min with mobile phase and relative humidity was controlled (33 %). Detection by dipping in anisaldehyde reagent, followed by heating at 100 °C for 3 min. Documentation and evaluation before derivatization under UV 366 nm and after derivatization under white light. The method was validated. It is specific and allows discrimination of Hoodia gordonii from Hoodia currorii, Hoodia parviflora, and the common adulterant prickly pear cactus (Opuntia ficus-indica). The sample is stable in solution and on the plate for at least 3 h, as well as during chromatography (2D test). After derivatization the chromatogram is stable for at least 1 hour. Precision (repeatability, intermediate precision, and reproducibility was good and the method is robust . The method is sensitive to changes in relative humidity. If relative humidity exceeds 47% the plate must be conditioned to 33% RH to ensure proper separation.
