      Validated HPTLC method for simultaneous determination of loratadine and desloratadine in presence of co-formulated drug
      R. YOUSSEF*, E. KHAMIS, M. EL-SAYED, Mona MONEIM (*Faculty of Pharmacy, Department of Pharmaceutical Analytical Chemistry, University of Alexandria, El-Messalah, Alexandria 21521, Egypt, rmmy1973@yahoo.com)

      J. Planar Chromatogr. 25, 456-462 (2012). HPTLC of loratadine (1) and desloratadine (2) on silica gel with methanol + 1 drop ammonia. Quantitative determination by absorbance measurement at 254 nm. The hRf values of (1) and (2) were 76 and 20, respectively. Linearity was in the range of 250-850 ng/band for (1) and 100-1000 ng/band for (2). Limits of detection and quantification were 90 and 250 µg/band for (1) and 30 and 100 µg/band for (2), respectively. Intra- and inter-day precisions were found to be less than 2 %. Recoveries were between 97.8 and 101.5 % for both (1) and (2).

      CBS 109, 2-4 (2012). Extraction of arabica coffee with 2 to 50 % robusta coffee by accelerated solvent extraction with tBME. A part was saponified with10 % ethanolic KOH solution for 2 h. HPTLC of coffee extracts and standards 16-O-methylcafestol (16-OMC) and 16-OMC esters on silica gel with toluene - ethyl acetate - acetic acid 93:7:1 for 16-OMC esters and with tBME - chloroform 1:1 for 16-OMC. Detection by spraying with vanillin sulfuric acid (1 g in 250 mL ethanol and 2 mL of sulfuric acid, prepared freshly) and heating for 1 min at 80 °C. Quantitative absorption measurement at 530 nm. The LOD was 163 ng/band. After saponification the LOD of free 16-OMC was 43 ng/band. Thus 2 % robusta can be detected in a coffee blend.
