      P. SAMTEN, P. WETWITAYAKLUNG, N. KITCHAROEN, U. SOTANAPHUN* (*Silpakorn Univ. Dep. of Pharmacognosy, Nakhon-pathom 73000, Thailand)

      Acta Chromatographica 22 (2), 227-236 (2010), DOI:10.1556/AChrom.22.2010.2.6. TLC of piperine, the bioactive constituent of black pepper (Piper nigrum), on silica gel with dichloromethane – ethyl acetate 9:1 at 30 °C in a twin-trough chamber saturated for 30 min. Detection under UV light at 254 nm and documentation with a digital camera. Based on the image a density profile plot was established by Scion Image software, which allowed to calculate the concentration of piperine by comparison of the peak areas of samples and piperine standards. The linearity was in the range of 24-84 ng/zone (r2=0.9927). The limits of detection and quantitation were 0.35 and 1.05 ng/zone, respectively. Precision (repeatability, n=6) and intermediate precision (2 days, n=12) both are below 2.6 %RSD. Recovery is between 96.7-101.4 %.

      Development of a quantitative high-performance thin-layer chromatographic method for sucralose in sewage effluent, surface water, and drinking water
      Gertrud MORLOCK*, L. SCHUELE, S. GRASHORN (*Univ. of Hohenheim, Inst. of Food Chem., Garbenstrasse 28, 70599 Stuttgart, Germany)

      J. Chromatogr. A 1218 (19), 2745-2753 (2011). HPTLC of sucralose in waste water on silica gel with isopropyl acetate – methanol – water 15:3:1. The developing time was 15 min. Detection with p-aminobenzoic acid reagent. Quantification by absorbance measurement at 400 nm. The limit of quantification was 100 ng/L at a recovery rate of 80 % and the extraction of a 0.5 L water sample. An interlaboratory trial in 2008 showed good agreement of the sucralose content determined in four water samples by HPTLC and other methods (HPLC–MS/MS or HPLC–TOF-MS). The good accuracy and high sample throughput capacity proved HPTLC as a well suited method for quantification of sucralose in various aqueous matrices.

      Determination of organophosphorus pesticides in rice by TLC
      D. LIU*, C. QIAN, Y. WANG (*Dept. of Applied Chemistry, College of Science, China Agriculture University, Beijing 100193, P.R., China)

      Asian Journal of Chemistry 23(5), 2011-2013 (2011). Methods are reported for determination of organophosphorus pesticides using TLC-cholinesterase inhibition as well as GC-FID. The powdered rice sample was initially extracted with ethyl acetate. The extract was cleaned up by GPC, eluted with cyclohexane - ethyl acetate 1:1, evaporated, and taken up in acetone. This extract was analysed by TLC on silica gel with ethyl acetate to a developing distance of 10-12 cm. After development the plate was air dried, exposed to bromine vapors, sprayed with enzyme solution and incubated at 37 °C for 30 min and sprayed with the reagent. White spots appeared against bluish-red background. The sample was also analysed by GC and the GC method was very sensitive. However, the TLC method is recommended for preliminary screening of samples.

      J. of Chromatogr. A 1218 (33), 5693-5704 (2011) A micro-TLC platform for the fast analysis of low-molecular mass compounds from spirulina samples was developed. The target compounds were extracted with methanol, acetone or tetrahydrofuran. HPTLC on RP-18W with acetone - n-hexane 3:7 in an unsaturated chamber using a temperature controlled micro-planar chromatographic device based on a horizontal chamber. Detection under visible light before and after exposure to iodine vapor. Pictures of the chromatograms were acquired with an office scanner and digitalized. The quantitative data was analyzed using cluster analysis and principal components analysis. With this method it was possible to distinguish genuine spirulina and non-spirulina samples as well as fresh and expired commercial products.
