J. Planar Chromatogr. 19, 398-400 (2006). HPTLC of curcumin, piperine, and thymol on silica gel, pre-washed with methanol, without chamber saturation with toluene - ethyl acetate - methanol 18:2:1. Quantitative determination by absorbance measurement at 420 nm for curcumin, 333 nm for piperine, and 277 nm for thymol. Limit of detection for curcumin was 25 ng, for piperine 5 ng, and for thymol 50 ng. Rapid identification of the three compounds is also possible by spraying the plate with anisaldehyde in sulfuric acid reagent.
Acta Chrom. 13, 154-160 (2003). Samples of nicotine were exposed to air and UV light and the products formed (nicotyrine, cotinine, and trans-3'-hydroxycotinine) were separated by TLC on RP-18 with acetonitrile – water 22:3 in a horizontal chamber. Visual evaluation under UV 254 nm, and under white light after derivatization with Dragendorff’s reagent. Quantitative determination by absorbance measurement at 260 nm. GC–MS analysis was performed to confirm the identities of the nicotine transformation products.
J. AOAC Int. 90, 358-363 (2007). TLC of diosgenin on silica gel with n-hexane - ethyl acetate 4:1 with chamber saturation for 15 min. Detection by dipping into a modified anisaldehyde-sulfuric acid reagent (0.1 % anisaldehyde in 2 % sulfuric acid) in order to reduce charring and background interference, followed by drying for 10 min under hot air and heating at 105 °C for 10 min. Quantitative determination by absorbance measurement at 428 nm.
Chromatographia 65 (1-2), 105-110 (2007). HPTLC of seven pharmaceuticals, enrofloxacine, oxytetracycline, trimethoprim, sulfamethazine, sulfadiazine, sulfaguanidine and penicillin G/procaine in production wastewater (obtained by solid-phase extraction on hydrophilic-lipophilic balance cartridges with methanol) on cyano phase with 0.05 M oxalic acid - methanol 81:19 after optimization of chromatographic separation by systematic variation of the mobile phase composition using genetic algorithm approach. Quantification by videodensitometry at 254 and 366 nm. Validation of the method by investigation of linearity ranges (1.5 - 15.0 µg/L for enrofloxacine, 100 - 500 µg/L for oxytetracycline, 150 - 600 µg/L for trimethoprim, 300 - 1100 µg/L for sulfaguanidine and 100 - 400 µg/L for sulfamethazine, sulfadiazine and penicillin G/procaine, R > 0.991), its mean recoveries (74.6 - 117.1% and 55.1 - 108.0% for wellspring water and production wastewater, respectively). Application of the method in determination of pharmaceuticals in wastewater samples from pharmaceutical industry.
J. Liq. Chromatogr. Relat. Technol. 28, 677-691 (2005). HPTLC of podophyllotoxin and podophyllin on RP-18 in a twin trough chamber with acetonitrile - water 2:3. Densitometric measurement of lignans in absorption mode at 217 nm.
J. Chromatogr. A 1164 (1-2), 298-305 (2007). TLC using staining reagents is fast, versatile and sometimes the only viable method method for analyzing organic compounds without chromophores. Investigation of quantitative TLC using staining reagents in combination with modern image analysis software showed that it is possible to get reliable measurements, suitable for high-throughput screening or physical organic investigations. Illustration of the range of detection and the errors for the different parts of the process, which are largely due to the staining process but can be diminished by measuring ratios of compounds.
J. Planar Chromatogr. 20, 19-25 (2007). TLC of fructooligosaccharides with raftilose as standard on silica gel impregnated with sodium acetate with butanol - acetic acid - water 2:2:1 in a saturated vertical twin-trough chamber with. Visualization with the diphenylamine-aniline-phosphoric acid reagent (in acetone). The blue-pink spots were also detected by reflectance densitometry at 370 nm. MALDI-MS was used for analysis of fructooligosaccharides.
CBS 98, 5-7 (2007). HPTLC of gatifloxacin on silica gel in a saturated twin-trough chamber with n-propanol - methanol - ammonia 25% 50:10:9 over 80 mm. Quantitative determination by absorbance measurement at 292 nm. The hRf value of gatifloxacin was 60 and selectivity regardnig matrix was given. Linearity was between 400 and 1200 ng/band. The intraday and interday precision both were below 0.03 %. The limit of detection and quantification was 2.7 and 8.3 ng/zone, respectively. Recovery was between 99.2 and 101.9 %. The HPTLC method was suited to study gatifloxacin stability under different stress conditions according to ICH guidelines (acid, base, heat, oxidation, photostability).
