J. Planar Chromatogr. 17, 109-112 (2004). HPTLC of econazole nitrate (1-[2-[4-chlorophenyl)methoxy]-2-(2,4-dichlorophenyl)ethyl]-1H-imidazole nitrate) on silica gel in a twin-trough chamber with n-butyl acetate - carbon tetrachloride - methanol - diethylamine 6:12:5:1. Quantitative determination by reflectance/absorbance measurement at 230 nm.
J. Planar Chromatogr. 17, 300-304 (2004). TLC of essential oils and thymol, carvacrol, geraniol as standards and streptomycin and gentamycin as positive controls on silica gel with toluene - ethyl acetate 93:7. Detection with ethanolic vanillin sulfuric acid. Quantitative determination at 500 nm. For bioautography the developed plates were dipped for 10 s in approximately 50 mL culture medium containing the test organism followed by drying for 2 min. After storage of the plates at 26 - 28 °C for 17 h they were dipped for 10 s in an aqueous solution (0.1 g / 60 mL) of 3-{4,5-dimethylthiazol-2-yl}-2,5-diphenyltetrazolium bromide (MTT) the layers were incubated at 28 °C for 2 h and then dipped in 70 % ethanol and dried at room temperature.
J. Planar Chromatogr. 17, 444-448 (2004). TLC of 16 naphthalimide dyes, 17 benzanthrone dyes, 20 triazine dyes, and 17 fluorescent brighteners on (mainly) silica gel with n-heptane - acetone 1:1 and 3:1, chloroform - methanol 1:1 and 2:1, n-heptane - benzene - chloroform 3:2:1, n-heptane - chloroform - acetone 2:2:1, n-butanol - pyridine - 25 % ammonia 1:1:1, chloroform - methanol - 25 % ammonia 11:5:1, n-propanol - 25 % ammonia 1:1 and 2:1, n-butanol - acetic acid - water 4:1:5. Quantitative determination by UV-scanning densitometry.
IPC 56th 2004, Abstract No. DP-33. An HPTLC method is reported for the standardization of Trikatukuc Curanam, an Ayurvedic preparation with Piper nigrum and Piper longum, both containing piperine as major alkaloid. HPTLC of piperine on silica gel with toluene - ethyl acetate 7:3 .Extraction with methylene chloride, the evaporated residue of the organic layer was taken in ethyl acetate and subjected to the analysis.The band corresponding to piperine was scanned at 338 nm. Linearity was 8-40 ng with recovery of 99.03 %.
J. Planar Chromatogr. 17, 238-240 (2004). HPTLC of aceclofenac and mosapride citrate (as internal standard) on silica gel in a twin-trough chamber equilibrated with the mobile phase with toluene - methanol - ethyl acetate - glacial acetic acid 550:250:200:1. Quantitative determination by densitometry at 284 nm.
leaves. J. Planar Chromatogr. 18, 244-248 (2005). Analytical and preparative TLC of coumarins from Peucedanum tauricum with bergapten, scopoletin, and coumarin A and B as standards on silica gel and on RP-2 with water - methanol 3:2 in horizontal chambers. Detection under UV light at 366 nm and densitometry at UV 366 and 320 nm. Re-chromatography with more selective mixtures of dichloromethane and acetonitrile 99:1 and 39:1. Identification by analytical co-chromatography with standards using mixtures of cyclohexane - ethyl acetate 3:1 and dichloromethane - acetonitrile 39:1.
J. Planar Chromatogr. 18, 203-206 (2005). TLC of primycin (a mixture of related compounds), streptomycin, dihydrostreptomycin on silica gel with A) n-butanol - water - methanol - acetic acid 4:2:1:1; and B) chloroform - methanol - water - 35% formic acid - n-butanol - formaldehyde 160:53:9:6:3:3. When using phase B repeated development improved the resolution. After development the plates were dried in a vacuum chamber at 100 °C. An efficient prewashing technique (with methanol - 35 % formic acid 1:1 followed by drying with hot air) made the TLC plates suitable for densitometric measurements at short wavelengths. Quantitative determination by absorbance measurement at 200 nm.
J. Pharm. Biomed. Anal. 39, 581-586 (2005). For post-production quality control of camptothecin derivatives irinotecan (CPT 11) and topotecan (TPT), HPLC and HPTLC methods have been developed which were suitable for identification, determination of purity and quantification. HPTLC on silica gel with methylene chloride - methanol - formic acid - water 82:24:2:1. After development, the plate was soaked in 15 % paraffin in n-heptane. Quantitative determination by fluorescence measurement at 366/>400 nm. The method was linear within the range of 100-1000 ng/mL for both CPT-11 and TPT. The method was validated for accuracy, precision, LOD, and LOQ.
