WANG (*The MOE Key Laboratory for Standardization of Chinese Medicines, the SATCM Key Laboratory for New Resources and Quality Evaluation of Chinese Medicines, and the Shanghai Key Laboratory for Compound Chinese Medicines, Institute of Chinese Materia Medica, Shanghai University of Traditional Chinese Medicine, 1200 Cailun Road, Zhangjiang Hi-Tech Park, Shanghai 201210, China)

      J. Chromatogr. A 1217(34), 5470-5476 (2010). Description of a combination method using high-speed counter-current chromatography and TLC as an antioxidant assay to separate antioxidant components from the fruits of Psoralea corylifolia by dipping in a ethanolic DPPH radical solution (2.54 mM) for autography. Bands with the DPPH scavenging activity were observed as white yellow bands on a purple background. High-speed counter-current chromatography of five flavonoids and three coumarins from the fruits of P. corylifolia with n-hexane - ethyl acetate - methanol - water 1011131. Preparative TLC for clean-up improves the substance yield from the fruits.

      Planar size exclusion chromatography of bitumen
      C.M. MARSH*. C.K. HLEKANE, (*Petrocol (Pty) Ltd., P.O. Box 413, Isando 1600, South Africa)

      J. Planar Chromatogr. 5, 417-423 (1992). A rapid planar size exclusion chromatographic method has been developed for analysis of the molecular mass distribution of bitumen. The main aims of the work were to determine optimum conditions for such analysis, quantify the technique if possible, and to determine whether the method could distinguish between bitumens of different grades and from different refineries. A case study is briefly described. Relative precision (repeatability) is ca. ± 5%.

      Selective separation of dodecyltrimethylammonium bromide from other cationic and nonionic surfactants
      A. MOHAMMAD*, N. HAQ (*Analytical Research Laboratory, Department of Applied Chemistry, Aligarh Muslim University, Aligarh-202002, U. P., India; mohammadali4u@rediffmail.com)

      J. Planar Chromatogr. 20, 347-351 (2007). TLC of DTAB on soil, silica gel, alumina, and kieselguhr with fifteen mobile phases, such as aqueous solutions of ammonium sulfate and urea, with chamber saturation for 10 min. Detection by spraying with modified Dragendorff reagent. Among the systems studied the best system for selective separation of DTAB from multicomponent mixtures of other surfactants was kieselguhr - 0.1 M ammonium sulfate. Semi-quantitative determination by spot-area measurement.

      Separation of some nonylphenyl ethylene oxide oligomers according to the length of the ethylene oxide chain
      T. CSERHATI, (Central Res. Inst. for Chem., Hungarian Acad. of Sci., P.O. Box 17, H-1525 Budapest, Hungary)

      J. Planar Chromatogr. 6, 70-73 (1993). TLC of non-ionic surfactants (e.g. nonylphenyl ethylene oxide oligomers) according to the length of the ethylene oxide chain on aluminum oxide with chloroform - acetonitrile mixtures. The optimum separation of pairs of surfactant oligomers with the longest ethylene oxide chains required eluents of the highest strength (highest acetonitrile concentration).

      Acta Chrom. 17, 272-291 (2006). TLC on silica gel with 0.1 M glutamic acid – methanol – acetone 111 has been found to be highly suitable for separation and identification of cationic and non-ionic surfactants. Visualization by use of Draggendorf reagent or iodine vapour. Spectro-photometric determination of tetradecyltrimethylammonium bromide at 670 nm after the spot extraction. The method has been used for identification of tetradecyltrimethylammonium bromide and Triton TX-100 in saline water, river water, and domestic waste water. The effects of sample pH, polarity of the alcohol and nature of the amino acid in the mobile phase, and the presence of alumina, kieselguhr, or cellulose in the silica gel layer have been examined.
