      HPTLC METHOD FOR THE ANALYSIS OF MELATONIN IN BULK AND PHARMACEUTICAL FORMULATIONs
      S. Agarwal*, H. Gonsalves, R. Khar (*Dept. of Pharmaceutical Science, Faculty of Pharmacy, Jamia Hamdard University, New Delhi 110062, India, agarwal_sp@yahoo.com)

      Asian J. Chem. 20(4), 2531-2538 (2008). TLC of melatonin on silica gel with toluene - ethyl acetate - formic acid 1091. Quantitative determination by absorbance measurement at 290 nm. The method was linear in the concentration range of 100 to 600 ng/spot. The recovery of the drug from tablets (by standard addition method) was 99.7 %. Statistical analysis proves that the method is repeatable, selective and accurate for the estimation of the drug. Forced degradation studies showed the effect of variations in pH, UV light and high temperature on the stability of melatonin. As the proposed method could effectively separate the drug from its degradation products, it can be employed as a stability indicating method.

      Estimation of metformin hydrochloride and glimepiride in multi-component formulation by HPTLC
      S. HAVELE*, S. DHANESHWAR (*Research and Development Centre in Pharmaceutical Sciences and Applied chemistry, Poona College of Pharmacy, Bharati Vidyapeeth University, Erandwane, Pune 411038, M.S., India)

      62nd Indian Pharmaceutical Congress Abstract No. F-235 (2010). TLC of metformin and glimepiride on silica gel with 0.5 % ammonium sulfate – water – methanol – ethyl acetate 2211. Quantitative determination by absorbance measurement at 254 nm. The method was found to be linear in the range of 300-500 ng/band for glimepiride and 150-250 µg/band for metformin.

      Analysis of a new potent hallucinogen, 25-B-NBOMe, in blotters by high-performance thin-layer chromatography
      B. DUFFAU*, C. CAMARGO, B. CASSELS, M. KOGAN, E. FUENTES (*Drug Analysis Section, Public Health Institute of Chile, Santiago, Chile, bduffau@gmail.com)

      J. Planar Chromatogr. 28, 395-397 (2015). HPTLC of 25-B-NBOMe (a N-(2-methoxy)benzyl-substituted phenylethylamine hallucinogen) in seized blotters (small, square pieces of absorbant paper impregnated with LSD or other hallucinogens) on silica gel with cyclohexane – toluene – diethylamine 1532. Quantitative determination by absorbance measurement at 298 nm. The hRF value for 25-B-NBOMe was 34. Linearity was in the range of 19-115 ?g/zone. LOD and LOQ were 7 and 22 ?g/zone. The intermediate precision was below 6.3 % (n=6). Average recovery was 98 %.

      Silica gel-assisted reversible ring-opening and ring-closure reactions on a thin layer silica gel chromatographic plate
      G. GÖNDÖS*, I. SZECSENYI, L. GERA, (*Dep. of Org. Chem., Jozsef Attila Univ. Dom tér, H-6720 Szeged, Hungary)

      J. Planar Chromatogr. 2, 163-164, (1989). Study of the chromatographic behavior of cis- and trans-2-m-chlorophenyl-, and 2-benzylhexahydroquinazolin-4(3H)-ones on silica by two-dimensional development with two times the same of four solvents at an interval of 20 hours. Detection by exposure to chlorine followed by spraying with TMD reagent. Ring-opening and ring-closure reactions were concluded.
