      A new stereoisomeric topological index (ISTI) for predicting the separation of stereoisomers in TLC
      A. PYKA, (Silesian Med. Acad., Fac. of Pharm., 4 Jagiellonska Street, 41-200 Sosnowiec, Poland)

      Part VII. J. Planar Chromatogr. 7, 389-393 (1994). TLC of stereoisomeric menthols and thujols (menthol, neomenthol, isomenthol, neoisomenthol, thujol, neothujol, isothujol, neoisothujol) on silica with hexane - ethanol 85:15 for menthols and benzene for thujols, each plate was developed three times. A new stereoisomeric topological index has been proposed (ISTI) which enables distinction between stereoisomers with hydroxyl groups in axial and equatorial positions.

      RP-TLC determination of S(+) and R(-) ibuprofen in drugs with the application of chiral mobile phase and UV densitometric detection
      J. KRZEK*, M. STAREK, D. JELONKIEWICZ (*Department of Inorganic and Analytical Chemistry, Collegium Medicum, Jagiellonian University, 9 Medyczna Str, 30-688 Kraków, Poland)

      Chromatographia 62 (11-12), 653-657 (2005). TLC of S(+) and R(-) ibuprofen on RP phase with beta-cyclodextrin - methanol 15:1. The UV densitometric detection was carried out at 222 nm. Limit of detection for S(+) and R(-) ibuprofen is 1 µg/mg. Precision and repeatability are good, the obtained results are within the range x mean ± 2. Recovery for both isomers is approximately 99 % and linearity was found to be in the range of 0.01-0.3 %. The presence of both isomers S(+) and R(-) ibuprofen was observed in all preparations at comparable concentrations from 56-66% for S(+) isomer and from 34-44 % for R(-) isomer.

      Resolution of beta blocker enantiomers by TLC with vancomycin as impregnating agent or as chiral mobil phase additive
      R. BUSHAN*, C. AGARWAL (*Department of Chemistry, Indian Istitute of Technology, Roorkee-247667, India; rbushfcy@iitr.ernet.in)

      J. Planar Chromatogr. 23, 7-13 (2010). TLC of the enantiomers of racemic atenolol, metoprolol, propanolol, and labetalol on silica gel using vancomycin as chiral impregnating agent or as chiral phase additive. With vancomycin as impregnating agent, resolution of the enantiomers of atenolol, metoprolol, propanolol, and labetalol was achieved with acetonitrile - methanol - water - dichloromethane 7:1:1:1, acetonitrile - methanol - water 6:1:1, acetonitrile - methanol - water - dichloromethane - glacial acetic acid 14:2:2:2:1, and acetonitrile - methanol - water 15:1:1. With vancomycin as mobile phase additive, resolution of the enantiomers of metoprolol, propanolol, and labetalol was achieved using acetonitrile - methanol - 0.56 mM aqueous vancomycin (pH 5.5) 15:1:2, and acetonitrile - methanol - 0.56 mM aqueous vancomycin (pH 5.5) - dichloromethane 18:2:3:2, respectively. Chromatograms were developed in glass chambers previously equilibrated with the mobile phase at 16 +/- 2 °C for 10-15 min. Detection by exposure to iodine vapor. The detection limits were 1.3, 1.2, 1.5. and 1.4 µg for each enantiomer of atenolol, metoprolol, propanolol, and labetalol, respectively.

      J. Planar Chromatogr. 29, 108-112 (2016). HPTLC of water-soluble vitamins (B1, B2, B6, C, and B12), amino acids and β-blocker enantiomers (carvedilol, (S)-(−)-propranolol hydrochloride, (±)-propranolol hydrochloride, and (±)-sotalol hydrochloride) on novel core–shell polymers consisting of hyperbranched (poly(ethyleneimine)) core surrounded by oligosaccharide shell (PEI-OS) as a component of the silica gel phase. The influence of the weight of the hyperbranched PEI core (5 and 25 kDa) was investigated. β-blocker enantiomers were separated using acetonitrile - methanol 7:3. PEI-maltose and PEI-lactose were the most effective polymers for the chiral separation of β-blockers.
