      Strait Pharm. J. 1, 53-55 (2014). Tiaojing Huoxue Jiaonang capsule is a TCM compound used clinically for the treatment of irregular menstruation, menstrual pain and other gynecological diseases. TLC on silica gel (1) for Salvia miltiorrhiza Bunge and protocatechuic aldehyde with dichloromethane – acetone – formic acid 60:5:2, detection by spraying with 5 % ferrum trichloride in ethanol and viewing under white light; (2) for Rehmannia glutinosa (Gaert.) Libosch. ex Fisch. et Mey. with petroleum ether (60-90 ˚C) – ethyl acetate 1:1, detection under white light after spraying with 2,4-dinitrophenylhydrazine – ethanol – hydrochloric acid 1:100:10. Quantitative determination of paeoniflorin by HPLC. Applying to real life samples indicated that the method was simple, specific, accurate, reproducible, robust and able to be the better alternative for the purpose to that specified in the Chinese Pharmacopoeia 2010.

      L-amino acids as chiral selectors for the enantioseparation of (±)-bupropion by ligand exchange thin-layer chromatography using Cu(II) complex via four different approaches

      Technology Roorkee, Roorkee – 247 667, India, rbushfcy54@gmail.com)

      J. Planar Chromatogr. 27, 367-371 (2014). TLC of (±)-bupropion on silica gel impregnated with 2 mM Cu(II) and 4 mM L-amino acid 1:2, with acetonitrile - methanol - chloroform 2:1:2. Detection by exposure to iodine vapors. The Cu(II) acetate–amino acid complex allowed efficient enantiomer separations. Four different approaches for impregnating/loading the ligand exchange reagent were evaluated. However, using a solution of Cu(II) acetate as mobile phase additive for the TLC plates impregnated with one of the L-amino acids allowed the best enantiomer separation.
