CBS 95, 2-4 (2005). TLC of seven biogenic amines (extracted with trichloroacetic acid from fish, followed by dansylation with dansyl chloride) on silica gel (prewashed with developing solvent) with benzene - chloroform - triethylamine 10:6:7 or 10:6:2 in horizontal developing chamber over 90 mm. Quantitative determination by fluorescence measurement at 365 nm/> 400 nm. Calibration using peak area, LOD 7.5 mg/kg, LOQ 56 mg/kg.
J. AOAC Int. 87, 827-833 (2004). TLC of trimetazidine dihydrochloride and degradation products (e. g. piperazine and 2,3,4-trimethoxymethyl benzene) on silica gel with methanol - ammonia 200:3. Detection under UV light at 254 nm and densitometry at 215 nm. The method was applicable over a concentration range of 2.00-9.00 µg/spot with a mean percentage accuracy of 99.86 +/- 0.92.
J. Planar Chromatogr. 18, 326-329 (2005). HPTLC of levonorgestrel on silica gel (prewashed with chloroform - methanol 1:1 and once with the mobile phase, dried and activated at 100 °C for 15 min) with toluene - 2-propanol 9:1 in an automatic multiple development chamber without chamber saturation. Visual examination under UV light at 254 nm; quantitation by densitometry at 250 nm.
J. Planar Chromatogr.18, 217-220 (2005). TLC of rose-hip extracts and (+)-catechin and (-)-epicatechin as standards on cellulose and silica gel in a horizontal chamber, saturated for 15 min, with the upper phase of ethyl acetate - water - formic acid - acetic acid 125:20:3:2. Visualization under UV light at 254 and 365 nm before and after spraying with bis-diazotized sulfanilamide. Quantitative determination by absorbance measurement at 254 nm.
J. Chinese Trad. Patent Med. (Zhongchengyao) 27 (3), 385-388 (2005). TLC of the extracts on silica gel with 1) ethyl acetate - acetone - formic acid - water 5:5:1:1; 2) chloroform - ethyl acetate - methanol - water 8:20:11:5; 3) n-hexane - ethyl acetate 9:1. Detection by spraying with 1) 5 % H2SO4 and 2) 10 % H2SO4, both in ethanol followed by heating at 105 ºC until the spots are visualized; 3) under UV 365 nm. Identification by comparison with the standard. Quantification of geniposide by HPLC. The analysis results for three real life samples are given.
J. Planar Chromatogr. 19, 10-14 (2006). OPLC of D-xylitol, L-arabitol, D-glucitol , D-xylose, L-arabinose, D-glucose, and L-rhamnose on silica gel with overrunning elution. Acetonitrile - acetic acid - water 63:33:5 was used as mobile phase. The upper limits of linearity were in the range 140-600 ng and detection limits were 15-50 ng per spot.
Talanta 61 (5), 581-589 (2003). TLC of clopidogrel bisulphate on silica gel with carbon tetrachloride - chloroform - acetone 12:8:3. Rf value of clopidogrel bisulphate was 0.30. Clopidogrel bisulphate was subjected to acid and alkali hydrolysis, oxidation, photodegradation and dry heat treatment. The drug was susceptible to acid - base hydrolysis, oxidation and dry heat degradation. Also the degraded products were well separated from the pure drug with significantly different Rf values. Quantitative determination by absorbance measurement at 230 nm. The linear regression data for the calibration plots showed good linear relationship with r2=0.999 in the concentration range of 200-1000 ng. The mean value of correlation coefficient, slope and intercept were 0.999±0.001, 0.093±0.011 and 8.83±0.99, respectively. The method was validated for precision, accuracy, ruggedness and recovery. The limits of detection and quantitation were 40 and 120 ng per spot, respectively.
CBS 96, 14-15 (2006). TLC of glibenclamide as adulterant in antidiabetic herbal drugs, on silica gel with toluene - ethyl formate - formic acid 5:4:1 in a saturated twin trough chamber over 150 mm. Detection under UV 365 nm, quantification of the image with VideoScan software. Rf of glibenclamide is 0.58. Results were compared with those obtained by UV spectrophotometry and HPLC and showed good correlation.
