J. Planar Chromatogr. 18, 194-198 (2005). HPTLC of rosuvastatin calcium (with aceclofenac as internal standard) on silica gel with toluene - methanol - ethyl acetate - formic acid 60:10:30:1. Quantitative determination by absorbance measurement at 265 nm. A good determination coefficient (r2 = 0.9999) was obtained for the linearity in the range of 1.0 to 15.0 µg of sample. For formulation and bulk drug the mean percentage assay was 100.09 +/- 0.20 and 100.07 +/- 0.48, respectively. The accuracy of the method was found to be 100.62 % and precision was found to vary from 0.01 to 0.77 %.
J. Planar Chromatogr. 19, 151-156 (2006). Investigation of the reversed-phase TLC retention behavior of a series of structurally diverse drugs, mostly basic compounds, with different aqueous mobile phase components. Phosphate buffer, phosphate-buffered saline, and morpholinepropanesulfonic acid, with or without the addition of n-decylamine, at pH 7.4, and phosphate buffer at pH 11.0 were used with different portions of methanol as mobil phase. TLC of amitriptyline, chlorpromazine, diltiazem, fluoxetine, nifedipine, nimesulide, norfluoxetine, nortriptyline, phenazine, pindolol, promethazine, propanolol, protriptyline, tioconazole, and trimethoprim on RP18 with phosphate buffer pH 7.4, phosphate-buffered saline, 3-morpholinopropanesulfonic acid pH 7.4, 3-morpholinepropanesulfonic acid + 0.2 % n-decylamine pH 7.4, and phosphate buffer pH 11.0 in pre-saturated chambers. Detection under UV light at 254 nm.
J. Liq. Chrom. & Rel. Technol. 27, 785-798 (2004). TLC of methyl, ethyl, isopropyl, butyl, hexyl, and benzyl nicotinate on silica gel and a mixture of silica gel and kieselguhr (heated at 120 °C for 20 min) with mixtures of n-hexane and acetone in the volume proportions 9:1, 4:1, 7:3, 3:2, 1:1, 2:3, 3:7, 1:4. Detection under UV light at 254 nm.
J. Planar Chromatogr. 19, 443-448 (2006). HPTLC of diclofenac sodium and paracetamol (with aceclofenac as internal standard) on silica gel, pre-washed with methanol, in a presaturated twin-trough chamber with toluene - ethyl acetate - methanol - formic acid 50:40:10:1. Quantitative determination by absorbance measurement at 260 nm. The method was validated regarding accuracy and precision.
Acta Chrom. 17, 292-301 (2006). TLC of ibuprofen and naproxen on silica gel pre-washed with methanol - water 9:1 and dryed at ambient temperature for 3 h. The plates were impregnated with a 0.03 M solution of L-arginine in methanol. Development with acetonitrile - methanol - water 5:1:1 containing several drops of glacial acetic acid for S-(+)-ibuprofen, and acetonitrile - methanol - water 10:2:3 containing several drops of glacial acetic acid for S-(+)-naproxen. Densitometry at 200, 205, and 210 nm for S-(+)-ibuprofen and at 202, 215, and 225 nm for S-(+)-naproxen. The investigations were performed by using three independent measurement techniques, all based on UV absorption: HPLC–UV, HPLC–DAD, and TLC–densitometry.
J. Liq. Chromatogr. Relat. Technol. 29, 1317-1330 (2006). TLC of 13 1H-pyrazolo[3,4-b]pyidine derivatives (e. g. 4-(3’- or 4’-X-phenylamino)-5-carbethoxy-1,3-dimethl-1-H-pyrazolo[3,4-b]pyridine derivatives) on hydrocarbon impregnated silica gel with acetone - phosphate buffer (0.01 M; pH 7.4) mixtures with concentrations ranging from 40-70 % in acetone. Detection under UV 254 nm.
Indian Drugs 44 (3), 205-208 (2007). HPTLC of frusemide (= furosemide) and spironolactone on silica gel with toluene - acetonitrile - glacial acetic acid 70:30:2, with chamber saturation for 15 min at room temperature. Development over 8 cm, followed by air drying. Quantitative determination by densitometry at 254 nm. Linearity was between 8 - 32 ng/µL and 20 - 80 ng/µL for frusemide and spironolactone respectively. The method was validated for accuracy and precision. The limit of detection and quantification for frusemide was 3 ng/µL and 8 ng/µL respectively, and for spironolactone 2 ng/µL and 6 ng/µL, respectively. Recovery by standard addition was 99.4-101% for both compounds.
Indian Drugs 44(10), 734 (2007). HPTLC of valdecoxib on silica gel with toluene - ethyl acetate 1:1. Quantitative evaluation by densitometry at 262 nm. Valdecoxib was well separated from rofecoxib. Linearity was between 800 and 1000 ng/zone. Recovery was 98.9 %.
