      Challenges in quantitative high-performance thin-layer chromatography – Part 2
      I. KLINGELHÖFER, Gertrud E. MORLOCK* (*Justus Liebig University Giessen, Chair of
      Food Science, Interdisciplinary Research Center (IFZ) and Institute of Nutritional
      Science, Heinrich-Buff-Ring 26?32, 35392 Giessen, Germany, Gertrud.Morlock@uni-giessen.de)

      J. Planar Chromatogr. 30, 411-417 (2017). HPTLC of paraben solutions and a complex matrix such as honey spiked with 5-hydroxymethylfurfural to study the influence of different application parameters on quantitative analysis. The investigated parameters included application geometries (spot, band and area) and their respective application modes (contact and spray-on), various dosage speeds, different band lengths, overspotted application versus application of mixture solutions as well as influence of the dosing volume on the result. These parameters have influence on method development and validation results.

      The behaviour of some phenolic acids and aldehydes on thin layers of silica gel impregnated with Fe(III)
      O. HADZIJA, M. TONKOVIC, S. ISRKIC, (The Ruder Boskovic, P.O. Box 1016, YU-41001 Zagreb)

      J. Liquid Chrom. 9, 3473-3478 (1986). TLC separation of p-hydroxy phenylacetic acid, m- and p-hydroxybenzoic acid, vanillic, salicylic and syringic acid, p-hydroxybenzaldehyde, vanillin and salicylaldehyde on silica and Fe(NO3)3-impregnated silica with 11 solvent systems. Detection on plain plates by spraying with methanolic FeCI3 solution (1 %) or saturated solution of o-dianisidine in acetic acid or by UV absorbance. Differences between Rf values (on plain and on impregnated silica) can be used as one of the parameters in the identification of some phenolic aldehydes or acids.

      Enantiomeric separation of chiral carboxylic acids, as their diastereomeric carboxamides, by thin-layer chromatography
      P. SLEGEL, G. VERECZKEY-DONATH, L. LADANYI, M. TOTH-LAURITZ, (EGIS Pharm., 1475 Budapest, Hungary)

      J. Pharm. Biomed. Anal. 5, 665-673 (1987). Description of a TLC method for enantiomeric separation of chiral carboxylic acids using chiral derivatization and non-chiral TLC conditions to separate diastereomeric carboxamides using „levobase“, (1R, 2R)- (-)-1- (4-nitrophenyl)-2-amino-1, 3-propanediol, and „dextrobase“; the enantiomers of levobase, as chiral derivatizing agents for carboxamide formation in the presence of dicyclohexylcarbodiimide as coupling agent. Good resolution was obtained for a wide range of carboxylic acid enantiomeric pairs containing 1 to 2 chiral centers .
