      HPTLC analysis of amino acids in Biomphalaria glabrata infected with Schistosoma mansoni
      J. PACHUSKI, B. FRIED*, J. SHERMA, (*Dept. of Chem., Lafayette Col., Easton, PA 18042, USA)

      J. Liq. Chrom. & Rel. Technol. 25, 2345-2349 (2002). HPTLC of 19 amino acids (i. a. histidine, lysine, alanine, methionine, threonine, asparagine, proline, and leucine/isoleucine) on i.a. silica gel with preadsorbent sample application zone and on cellulose with n-butanol - acetic acid - water 3:1:1. Detection of the zones was achieved by spraying the developed and air-dried plates with ninhydrin reagent, air drying for 30 min and heating for 10 min at 110°C. Densitometry at 495 nm for histidine and 610 nm for all other acids.

      Detection and separation of amino acids as butylthiocarbamyl derivatives by Thin-Layer Chromatography with the iodine-azide detection system
      D. KAZMIERCZAK, W. CIESIELSKI, R. ZAKRZEWSKI* (*Department of Instrumental Analysis, University of Lódz, Pomorska 163, 90-236 Lódz, Poland; robzak@chemul.uni.lodz.pl)

      J. Liq. Chromatogr. Relat. Technol. 28, 2261-2271 (2005). HPTLC of 21 butylthiocarbamyl-amino acids on silica gel in a saturated horizontal chamber. Pre-chromatographic derivatization with 2-propanol - BITC - triethylamine was carried out after application of the amino acids. For the reaction the plate was placed in a glass chamber in a thermostat at 40 °C for 30 min. Then the plate was developed with ethanol - methanol - chloroform 1:1:2. Detection by spraying with a freshly prepared mixture of 3 % sodium azide and 0.5 % starch solution adjusted to pH 5.5 and exposed to iodine vapor for 5 s. Quantities in the range of 2-90 pmol per spot were detected.

      Optimization of the TLC separation of seven amino acids
      Iva REZIC*, T. REZIC, L. BOKIC (*Laboratory of Analytical Chemistry, Department of Applied Chemistry, Faculty of Textile Technology, University of Zagreb, Croatia; iva_rezic@net.hr)

      J. Planar Chromatogr. 20, 173-177 (2007). TLC of seven amino acids (alanine, asparagine, cysteine, leucine, phenylalanine, serine, threonine) on microcrystalline cellulose with butanol - glacial acetic acid - water 60:19:21. Detection by spraying with 3 % ethanolic ninhydrin solution and heating. The performance of this mobile phase was confirmed experimentally. Optimization by use of the experimental design software packages Design-Expert 6 and Statistica.

      TLC separation of amino acids with a green mobile phase
      A. MOHAMMAD*, N. HAQ (*Analytical Research Laboratory, Department od Applied Chemistry, Faculty of Engineering and Technology, Aligarh Muslim University, Aligarh 202 002, India; alimohammad08@gmail.com)

      J. Planar Chromatogr. 23, 260-264 (2010). TLC of 15 amino acids on silica gel and alumina (with or without impregnation) with micellar solutions of cetrimide and cetylpyridiniun chloride and aqueous solutions of dextrose with chamber saturation for 10 min. A TLC system comprising of silica gel impregnated with micellar solution of cetrimide (5.0 mM) as stationary phase and 40 % aqueous solution of dextrose as mobile phase was best suitable for the separation of amino acids. Detection by spraying with 0.3 % ninhydrin solution in acetone and heating for 15-20 min at 60 °C.

      Detection and determination of caffeine, taurine, and arginine in shampoos
      Michaela OBERLE*, M. SCHULZ (*Merck KGaA, MM-LER-CP, Frankfurter Str. 250, 64293 Darmstadt, Germany, michaela.oberle@merck-group.com)

      CBS 111, 5-6 (2013). HPTLC of caffeine, taurine, and arginine in shampoo samples extracted with isopropanol, on silica gel over 50 mm with isopropanol - n-heptane - water 7:3:1 for caffeine and isopropanol - water 4:1 for arginine and taurine. Detection under UV 254 nm (caffeine) and after spraying with ninhydrin reagent under white light (arginine and taurine). Quantitative absorbance measurement at UV 254 nm for caffeine and UV 600 nm for arginine and taurine. The hRF of caffeine was 54. Precision (%RSD) for the polynomial calibration of caffeine was 3.9 % (n=3). The hRf of taurine was 24. Arginine remained at the start position under these conditions. The content of taurine and caffeine found in shampoos corresponded to the usual amount of 0.1 % active ingredient in a formulation.
