J. Planar Chromatogr. 17, 369-371 (2004). TLC of 9-phenylxanthene derivatives (fluorescein, erythrosine, eosin, rhodamine B, and their allyloxy-derivatives) on silica gel with benzene - methanol 5:1, toluene - ethanol 7:1, acetontrile - water 7:1, toluene - ethyl acetate - methanol 1:5:2. Detection under UV light at 254 nm or with iodine vapor. Quantitation by densitometric scanning.
J. Planar Chromatogr. 17, 229-232 (2004). HPTLC of progesterone on silica gel in an automatic multiple development chamber (AMD) with toluene - 2-propanol 9:1 without chamber saturation and with 10 min drying time. Visual inspection under UV light at 254 nm. Quantitative determination in reflectance mode at 252 nm. Limits of quantitation and detection were 25 and 5 ng/zone.
IPC 56th 2004, Abstract No. GP-3. Simultaneous HPTLC determination of valdecoxib and tizanidine in tablets on silica gel with n-butyl acetate - formic acid - chloroform 7:3:2. Quantitative determination by densitometric scanning at 283 nm. The Rf values of valdecoxib and tizanidine were 0.78 and 0.39 respectively. Linearity range was 200 - 1000 ng/spot and 60 - 300 ng/spot respectively. Mean recovery for both of the compounds was 99.57 – 101.28 %. The method was validated for accuracy, precision, linearity, LOD, and LOQ.
J. Planar Chromatogr. 18, 181-187 (2005). Cameras and image-analysis techniques have been used for the evaluation of TLC and gel-electrophoresis for several years. A computer program has been developed to enable use of inexpensive image-generating systems such as CCD cameras, webcams, or flat-bed-scanners for the evaluation of TLC and electrophoresis separations in UV and white light. TLC of flavonoids and anthraquinone dyes on silica gel with water - formic acid - methyl ethyl ketone - ethyl acetate 1:1:3:5 and toluene - cyclohexane 2:1, respectively.
J. Planar Chromatogr. 18, 423-426 (2005). HPTLC of antibiotics (sulfadimidine, sulfadiazine, sulfaguanidine, trimethoprim) on silica gel without chamber saturation in a twin-trough chamber with chloroform - methanol 89:11. Quantification by videodensitometry at 254 nm. Limit of detection was 0.05 µg per spot for sulfadimidine, sulfadiazine, and sulfaguanidine, and 0.1 µg per spot for trimethoprim.
Abstract G-28, IPC (2005). HPTLC of rosuvastatin on silica gel with chloroform - methanol - toluene 3:1:1. Quantitative determination by absorbance measurement. The hRf value of rosuvastatin was 53, recovery rate was between 98-102 %, LOD was 8 ng/spot and LOQ 26 ng/spot.
J. AOAC Int. 88, 1549-1554 (2005). TLC of polymyxin B, framycetin, and dexamethasone on silica gel with methanol and methanol - n-butanol - 25 % ammonia - chloroform 14:4:9:12 for framycetin and polymyxin B. Quantitative determination by densitometry at 550 nm after detection with 0.3 % ninhydrin solution. Dexamethasone was separated with cyclohexane - ethyl acetate 2:3, quantitative determination by absorbance measurement at 245 nm. Similar accuracy, relative standard deviation values from 1.49 to 2.47 % and relative error values from 0.02 to 0.81 % are comparable to those obtained with the reference methods.
J. Chinese Trad. Patent Med. (Zhongchengyao) 27 (3), 272-275 (2005). TLC of the extracts on silica gel with 1) n-hexane - chloroform - methanol 15:8:2; 2) n-hexane - ethyl acetate 9:1; 3) chloroform - benzene - glacial acetic acid 7:2:1. Detection 1) by exposing to iodine vapours; 2) under UV 365 and 254 nm. Identification by comparison with the standard. Quantification of usnic acid by densitometry at 290 nm. Validation by investigating the linearity range (0.50 - 2.50 µg/spot, r = 0.999), precision (RSD = 2.26 %, n= 5, within plate, and 2.97 %, n = 5, plate-to-plate), and standard addition recovery (97.5 %, RSD = 2.61, n = 5).
