Asian J. Chem. 18(2), 1078-1084 (2006). TLC of nimesulide and diclofenac sodium on silica gel with n-hexane - ethyl acetate - chloroform - acetic acid 16:2:3:1. Quantitative determination by absorbance measurement at 256 nm. The hRf value of nimesulide was 3 and of diclofenac sodium 57. Linearity was between 1.0 and 3.2 µg/zone for nimesulide and 0.5 and 1.6 µg/zone for diclofenac sodium. The recoveries (by standard addition method) were in the range of 99.1 and 101.0 for both drugs. The proposed method is precise and accurate and can be used for routine analysis of nimesulide and diclofenac sodium capsule formulation.
J. Planar Chromatogr. 22, 97-100 (2009). TLC of (+)-catechin, (-)-epicatechin, (-)-epigallocatechin, (-)-epicatechin gallate, (-)-epigallocatechin gallate, theaflavin, theaflavin 3-gallate, theaflavin 3’-gallate, and theaflavin 3,3’-digallate on polyamide phase in a horizontal chamber (saturated for 15 min) by twofold development with chloroform - methanol 2:3 or n-butanol - acetone - acetic acid 5:5:3. Separation of the flavonols myricetin, quercetin, kaempferol, rutin and the phenolic acids gallic acid, chlorogenic acid, and caffeic acid was achieved by twofold development with chloroform - methanol 2:3. Detection by spraying with iron(III) chloride solution and evaluation under daylight. Quantitative determination by absorbance measurement at 600 nm.
J. Planar Chromatogr. 22, 43-47 (2009). HPTLC of alpha-solanine and alpha-chaconine on silica gel with dichloromethane - methanol - 2.5 % ammonia 175: 75:11 in a horizontal chamber saturated for 15 min. After drying and heating at 90 °C for 25 min detection by dipping twice in modified Carr-Price reagent (antimony(III) chloride in acetic acid - dichloromethane), followed by heating at 110 °C for 3 min. Quantitative determination by absorbance measurement at 560 nm. Linearity was between 30 and 700 ng. The limit of detection was 5-20 ng/zone depending on the sample matrix, the limit of quantification was 30 ng/zone. The ratio of alpha-chaconine and alpha-solanine was between 4:1 to 2:1 for all analyzed samples.
J. Planar Chromatogr. 22, 83-88 (2009). TLC of isoniazid, pyrazinamide, ethambutol, and aminosalicylic acid on RP-18 in a horizontal chamber at 20 °C with acetonitrile - water 3:7. The mobile phase was modified by adding copper(II) chloride to the mixture at a constant concentration of 0.05 M. Detection under UV light at 254 nm. Quantitative determination by absorbance measurement in the range 200 - 700 nm with a TLC scanner equipped with a diode-array detector.
J. Planar Chromatogr. 21, 277-282 (2008). TLC of clotrimazole and metronidazole on silica gel in a twin trough chamber saturated for 10 min with toluene - ethyl acetate - methanol - acetic acid 55:2:6:1. Quantitative determination by absorbance measurement at 220 nm.
Indian J. Pharma. Sci. 70(6), 831-834 (2008). HPTLC of sumatriptan on silica gel (pre-washed) with methanol - water - glacial acetic acid 40:80:1 with chamber saturation for 10 min. Quantitative determination by absorbance measurement at 230 nm. The hRf value was 64. The method was linear in the range of 200-800 ng/spot.
Anal. Chem. 80, 6821-6823 (2008). HPTLC of Cr3+ and Cr 6+ on silica gel in a saturated chamber with distilled deionized water and Triton-X-100 in concentrations between 0.001 and 0.1%, which is around the critical micelle concentration. Separation was achieved in seconds over 1 cm. Laser ablation was used to volatilize the chromium species directly from the chromatographic material prior to ICP-MS detection. The reliability of calibration was satisfying with precisions between 3 - 30 % and detection limits in the low ng-range. Silicium, which is present in the silica gel plate, was discussed as suitable internal standard.
60th Indian Pharmaceutical Congress PA-217 (2008). HPTLC of oleanolic acid in total methanolic extract of fruits of Randia dumetorum lam. on silica gel with toluene - ethyl acetate - acetic acid 70:30:1 in a twin trough chamber saturated for 10 min. Detection by treatment with 10 % sulphuric acid in methanol, followed by heating at 110 °C and immediate densitometric evaluation. Quantitative determination by absorbance measurement at 540 nm. The method was linear in the range of 50-500 ng/spot. Recovery was in the range of 99.4-100.8 %.
