      New visualizing agents for unsaturated higher fatty acids in TLC
      W. WARDAS*, A, PYKA, (*Silesian Acad. of Med., Fac. of Pharm., 4 Jagiellonska Street, PL-41-200 Sosnowiec, Poland)

      J. Planar Chromatogr. 10, 63-67 (1997). TLC of unsaturated fatty acids (cis-6-, cis-9-, cis-11-, cis-12-, cis-13-, trans-9-, trans-11-octadienoic acid, cis-6,9,12- and cis-9,12,15-octadecatrienoic acid) on silica, silica-kieselguhr and silica impregnated with a 10% solution of paraffin in hexane. Eluents were heptane - acetone 4:1 for adsorption TLC and acetic acid - water 9:1 for partition TLC. Visualization with aqueous solutions (0.5 g/L) of aniline blue, alkaline blue, brilliant green, and neutral red; and in 2% aqueous sodium hydroxide solutions (0.5 g/L) of bromothymol blue, thymol blue, bromophenol blue, phenol red, helasol green, bromocresol green, and brilliant cresyl blue. The most advantageous visualizing effects in adsorption and partition TLC were obtained with aniline blue. Detection limits 2-3 µg of unsaturated fatty acids.

      Research on color channel selection, three-dimensional visualization, and acquisition time of computerized image analysis for one-dimensional planar separation
      T. TANG (Tang Tie-Xin)*, H. WU (Wu Hong) (*Center for Medicinal Plants Research, South China Agricultural University, 510642 Guangzhou, China)

      Chromatographia 70 (1-2), 305-308 (2009). Description of color channel selection, three-dimensional visualization, and acquisition time of computerized image analysis for one-dimensional planar separation, known as computerized image analysis or video densitometry. This is an efficient, low-cost technique for quantitative and qualitative analysis of planar separations, e.g. planar chromatography and gel electrophoresis. The image of the TLC plate is captured in black and white, then the proper color channel of the image is selected in order to enhance the signal-to-noise ratio. To facilitate image evaluation a three-dimensional visualization of the planar image was applied by use of OpenGL technology. It was found that the sensitivity is increased by use of longer acquisition times whereas linearity of quantitative analysis is reduced.

HPTLC of saffron and its main adulterants (sumac, turmeric, safflower, common madder, quinoline yellow, sunset yellow and tartrazine) on silica gel with 1-butanol – acetic acid – water 4:1:1. Images were captured under visible light and subjected to MATLAB software. The method included image preprocessing capable of identifying such adulteration based on modelling that includes principal component analysis, k-means and chemometric methods such as partial least squares discrimination analysis, variable selection (loading weight and variable importance in projection) and linear discriminant analysis.

      Anal. Biochem. 152, 391-395 (1986). Description of a method for quantification of 3H and 14C on thin layers after two-dimensional TLC. After impregnation with 50 % 2,5-diphenyloxazole-tetrahydrofuran, quantitative imaging of the distribution of b-ray-emitting isotopes on the chromatogram was carried out at room temperature using a TV camera system. The system consists of a 2-stage microchannel plate image intensifier, a low-lag vidicon, and an image processor.
