HPTLC of 16 alkoxy-phenylbenzamide derivatives on silica gel pre-coated overnight with n-hexane - paraffin oil 19:1, with a mixture of organic solvent - water. The ratio of the organic solvent component (n-hexane, acetone, ethyl alcohol, methyl alcohol, and dioxane) changed in steps of 5 vol %. Quantitative determination by absorbance measurement under UV light (no wavelength given). Lipophilicity parameters (lipophilicity, extrapolated to zero concentration of organic modifier; specific hydrophobic surface area) were calculated from the retention data.

      A. SAHANA, S. DAS*, R. SAHA, M. GUPTA, S. LASKAR (*Dep. of Chem., The Univ. of Burdwan, Burdwan 713104, India)

      J. Chromatogr. Sci. 49 (8), 652-655 (2012). Synthesis of a new reagent by coupling anthracene moiety to L-leucine. The reagent has been characterized by different analytical techniques and is suitable for easy identification of various amino acids on TLC plates by developing distinguishable colors with a detection limit between 0.1–0.5 µg in cold condition and 0.1–0.4 µg after heating. It was found that this reagent also binds with different amino acids very strongly in methanolic solution. Estimation of equilibrium binding constants with different amino acids showed that the values of the binding constants ranged from the lowest for L-tyrosine of 6.86 × 103 dm3/mol to the highest for L-arginine monohydrochloride of 8.86 × 105 dm3/mol at 25 °C. A theoretical study (Hartree-Fock) was also performed to investigate the interaction of the reagent with a representative amino acid (glycine).
