Chromatographia 28, 197-202 (1989). HPTLC of 2-aminopyridine, DP-I and DP-II on silica with ethyl acetate - toluene - diethylamine - 10:10:5 and toluene - ethanol - acetic acid 8:1.2:0.5. Quantification by densitometry at 296 nm in the concentration range of 600 - 1200 ng 2-aminopyridine/spot and 300 - 600 ng DP-I and DP-II/spot.
J. Planar Chromatogr. 23, 190-192 (2010). After sample application as bands and fully off-line OPLC separation followed by drying, the separated bands were compressed bilaterally, in parallel, perpendicular to the direction of development, by use of a strong eluent and capillary driven chromatography. To introduce the eluent for band compression onto the layer a simple manual tool equipped with parallel foam strips was constructed. OPLC of a black tea leaf extract and caffeine, theophylline, and theobromine on silica gel (prewashed with acetonitrile - water 17:3) with toluene - acetic acid 3:2. Quantitative determination by densitometry at 280 nm. After band compression 20 ng/zone theophyllin and theobromine could be detected by densitometry in the xanthine standard mixture at a loading of 20 µg/10 mm. These compounds were not visible in the original, uncompressed chromatogram.
Med. Industry (Yiyao Gongye) 16, 19-21 (1985). (Chinese). (Thin-layer chromatographic analysis of various mixed nucleotides.) TLC of deoxyribonucleotides (d AMP, d GMP, d CMTTP and d TMP) and ribonucleotides (AMP, GMP, CMP, UMP) on cellulose with isobutyric acid - acetic acid -1 N NH3 10:1:5 or saturated (NH4)2SO4 - 1 M sodium acetate - isopropanol 40:9:1. Quantification by densitometry. The method found is useful for the analysis of DNA and RNA.
J. Chromatogr. 543, 425-438 (1991). Determination of the retention of 21 nucleoside derivatives with various alkyl substituents in the 5'-position on alumina with dichloroethane - methanol , water - methanol , water - ethanol and water - 2-propanol eluent systems. Discussion of the anomalous retention behaviors of the nucleosides in each system.
Analyst 119, (1994). TLC screening of theobromine (TB), theophylline (TP), caffeine on silica with ethyl acetate - methanol - NH3 17:2:1. Detection under UV 254 nm, and by spraying with Dragendorff- iodine reagent. Quantification by HPLC.
LXXXV. Some 2-substitution derivatives of 5-(4-oxo-6-hydroxy-3,4-dihydro-5-pyrimidinyl)pentanoic acid. Coll. czechoslov. chem. comm. 48, 304-311 (1983). TLC of the title compound on silica with 1-propanol - NH3 -water 7:1:2. Detection by UV.
Proc. 6th Int. Symp. Instrum. Planar Chromatogr., (Interlaken 1991), Inst. Chromatogr., Bad Dürkheim, FRG, 113- 117 (1991). Use of »simplex« method for the selection of the optimum solvent system for the qualitative determination of six cleavage products. RP-TLC on self prepared silanized silica with methanol - ethyl acetate - ether - 35% NH3 5:48:46:1 (optimum solvent system). Detection by exposure to iodine vapors.
IPA Convention, 2010, RA-PO 26. HPTLC of risedronate sodium on silica gel with water - methanol - 25 % ammonia 20:3:3. Densitometric evaluation at 262 nm. The method was linear in the range of 3-6 ng/band, recovery was 98.6 %. Results were comparable with HPLC results. The advantage of the HPTLC method is the simultaneous analysis of several samples.
