J. Planar Chromatogr. 18, 419-422 (2005). TLC of fenitrothion on silica gel in a horizontal chamber with ethyl acetate - n-heptane 1:4. Quantitative determination by scanning with a diode-array spectrophotometer from 191 to 612 nm.
J. Planar Chromatogr. 18, 234-239 (2005). TLC of Evolvulus alsinoides extracts and the marker EA 1, i.e. 3beta,23,24-trihydroxyolean-12-en-28-oic acid, on silica gel with n-hexane - ethyl acetate 7:3 in a saturated chamber. The marker EA 1 was detected under UV light at 366 nm as a yellow fluorescent band of Rf 0.8. Quantitative determination by absorbance measurement at 232 nm (=UV max of EA 1). Limit of detection 11.6 ng; satisfactory recovery from 93.3 to 96.6 %. The marker was isolated from the aerial parts of Evolvulus alsinoides by preparative TLC.
Abstract GP-18, IPC (2005). HPTLC of nimesulide and chlorzoxazone in tablets on silica gel (prewashed with methanol) with toluene - acetone - ammonia 50:50:4. Paracetamol was used as internal standard. Quantitative determination by absorbance measurement at 265 nm. Nimesulide, chlorzoxazone and paracetamol showed hRf values of 80, 73 and 42, respectively. Linearity was obtained between 0.2-1.0 mg/mL with recovery rates of 99.6-100.3 % for both compounds.The method was validated for accuracy, precision, linearity, LOD, and LOQ.
J. AOAC Int. 87, 1319-1322 (2004). TLC of chlorpheniramine and pheniramine maleate in combination with other drugs in pharmaceutical preparations of tablets, syrups, eye and ear drops etc. on silica gel with cyclohexane - chloroform - methanol - diethylamine 9:8:1:2. Detection under UV light at 254 nm and quantitative determination by scanning at 260 nm. Recoveries of CPM and PM were 100.1 +/- 0.8 % and 100.1 +/- 0.9 %, respectively.
CBS 96, 11-13 (2006). HPTLC of isopropylthioxanthone (ITX) in food, on silica gel in horizontal developing chamber with toluene - n-hexane 4:1 over 50 mm. Quantitative determination by fluorescence measurement at UV 254/>400 nm. Polynomial calibration via peak height, working range was 20 - 200 µg/kg. LOD is 64 pg (n=3) and in spiked fatty matrix 1 µg/kg. Positive findings were confirmed by ESI-MS in selective ion monitoring mode at m/z 255 and 277 using a plunger-based extraction device. Further confirmation by DART directly coupled to TOF-MS.
J. Liq. Chrom. & Rel. Technol. 27, 1579-1592 (2004). TLC of an orange color standard before and after saponification (as beta-cryptoxanthin) on RP18 with acetonitrile - acetone - n-hexane 11:7:2 and acetone - water 9:1. Measuring the visible absorption spectra in the range of 370-700 nm by scanning densitometry with its maximum absorption wavelength at 455 nm.
Indian J. Pharm Sciences 67 (6), 762-764 (2005). HPTLC of fenofibrate in methanolic capsule extracts on silica gel with toluene - chloroform 7:3 with chamber saturation for 10 min. Quantitative determination by absorbance measurement at 296 nm. Linearity range was 1.2-3.8 g with recovery of 101.43 %. The proposed validated method was stability indicating and useful for routine analysis.
Indian J. Pharm Sciences 67 (6), 721-726 (2005). HPTLC of gallic acid in ethanolic extracts of rhizomes from curculigo orchioides on silica gel with toluene - ethyl acetate - acetic acid 25:15:1. Quantitative determination by absorbance measurement at 260 nm. The method was validated according to ICH guidelines. Rhizomes and their marketed formulation were found to contain 2.5 % and 5.0 % of gallic acid.
