      Application of a validated stability-indicating densitometric thin-layer chromatographic method to stress degradation studies on moxifloxacin
      S.K. MOTWANI*, R.K. KHAR, F.J. AHMAD, S. CHOPRA, K. KOHLI, S. TALEGAONKAR (*Department of Pharmaceutics, Faculty of Pharmacy, Jamia Hamdard, Hamdard Nagar, New Delhi 110062, India)

      Anal. Chim. Acta 582(1), 75 - 82 (2007). TLC of moxifloxacin both as a bulk drug and from pharmaceutical formulation on silica gel with n-propanol - ethanol - 6M ammonia 4:1:2. Quantification by absorbance measurement at 298 nm. The hRf value of moxifloxacin was 58. Linearity was in the range of 100–800 ng/spot. LOD and LOQ were 3.9 and 11.8 ng/spot, respectively. In stability studies (acid and alkali hydrolysis, oxidation, dry heat, wet heat, photodegradation) degradation products were well resolved from the standard drug. The method was suitable to investigate the kinetics of the acidic and alkaline degradation processes at different temperatures.

      T.H. DZIDO*, P.W. PLOCHARZ, A. KLIMEK-TUREK, A. TORBICZ, B. BUSZEWSKI (*Department of Physical Chemistry, Medical University, Lublin, Poland; tadeusz.dzido@am.lublin.pl)

      J. Planar Chromatogr. 21, 295-298 (2008). HPTLC of a test compound [1-(4-hydroxyphenylazo)-2-napthol] on RP-18 (prewashed with methanol) with acetonitrile - water - buffer (pH 4.8) in the desired volume ratio in a horizontal developing chamber saturated for 15 min. Quantitative determination by absorbance measurement with a diode array TLC scanner. The retention-composition relationship obtained with TLC is similar to those of pressurized planar electrochromatography and HPLC in the modifier concentration range 60-80 % but deviates substantially at higher modifier concentrations.

      Two new methods for early detection of the effects of herbicides in plants using biomarkers
      H.W. RAVN (Aarhus University, National Environmental Research Institute, Department of Terrestrial Ecology, PhytoChemLab, Vejlsoevej 25, P. O. Box 314, 8600 Silkeborg, Denmark, her@dmu.dk)

      J. Planar Chromatogr. 22, 65-71 (2009). Presentation of two simple and rapid HPTLC methods for early detection of the effects of herbicides using two different groups of plant biomarkers, which were developed as field tests (Herbicide Weed Response test - HWR-Test). Phytochemical changes can be detected before any morphological changes are visible on the plants. These changes are defined as biomarkers and can be detected by HPTLC-screening. After overall identification of the phytochemical biomarker pattern, two different biomarker groups, carbohydrates and amino acids, were detected using modified reagents for color reactions. Evaluation under daylight and videodensitometric analysis of digital images by VideoScan software. The screening method was previously described [H. W. Ravn, M. Hjorth, L. Lauridsen, P. Kudsk, S. K. Mathiassen, L. Mondolot, Bull. Environ. Contam. Toxicol. 75, 236-245 (2005)].

      Qualitative and quantitative determination of hydrolysable tannins and other polyphenols in herbal products from meadowsweet and dog rose

Detection of polyphenolic compounds under UV light at 254 and 366 nm before and after spraying with natural products reagent followed by polyethylene glycol reagent. Detection in white light after spraying with 1 % iron(III) chloride (for tannins and phenolic acids), vanillin-hydrochloric acid (flavonols) or bis-diazotised sulfanilamide (for all polyphenols). Quantitative determination of polyphenol contents by HPLC with UV detection. Meadowsweet flowers and rose hips with seeds yielded 55.5-124.8 and 0.4-1.3 mg/g of ellagitannins, respectively. The sum of detected polyphenols was 83.9-165.7 mg/g for Filipendulae ulmariae flos and 1.2-2.7 mg/g for Rosae pseudo-fructus cum fructibus.

      Y. KAWAI*, M. MIYOSHI, J. MOON, J. TERAO (*Department of Food Science, Graduate School of Nutrition and Biosciences, The University of Tokushima, Tokushima 770-8503, Japan)

      Anal. Biochem. 360 (1), 130-137 (2007). Determination of cholesteryl ester hydroperoxides, especially cholesteryl linoleate hydroperoxide isomers, by combination of TLC blotting with diphenyl-1-pyrenylphosphine fluorescent detection (DPPP-TLC blotting) and GC-electron ionization-MS (GC-EI-MS). After DPPP-TLC blotting of cholesteryl ester hydroperoxides fluorescent zones were obtianed which were extracted and derivatized by hydrogenation, transmethylation, and trimethylsilylation. The resulting methyl ester/trimethylsilylether derivatives of hydroxyoctadecenoic acid were then analyzed by GC-EI-MS using selected ion monitoring of isomer-specific fragment ions originating from the alpha-cleavage of the trimethylsilyloxyl group.
