J. Pharm. Biomed. Anal. 39, 581-586 (2005). For post-production quality control of camptothecin derivatives irinotecan (CPT 11) and topotecan (TPT), HPLC and HPTLC methods have been developed which were suitable for identification, determination of purity and quantification. HPTLC on silica gel with methylene chloride - methanol - formic acid - water 82:24:2:1. After development, the plate was soaked in 15 % paraffin in n-heptane. Quantitative determination by fluorescence measurement at 366/>400 nm. The method was linear within the range of 100-1000 ng/mL for both CPT-11 and TPT. The method was validated for accuracy, precision, LOD, and LOQ.
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.
Abstract G-25, IPC (2005). HPTLC of cefuroxime axetil in bulk and tablets on silica gel with chloroform - methanol - toluene 2:1:1 with chamber saturation for 30 min. Quantitative determination by absorbance measurement at 290 nm. The linearity was within the range of 300-900 ng/spot with an average recovery rate of 99.4 %. The method was validated as per ICH guidelines.
Indian Drugs 42 (10), 650-653 (2005). A simple rapid, precise and cost-effective HPTLC method has been developed for the determination of ursolic acid in Oscimum sanctum (Tulsi) leaves and its formulations (Tulsi ghan tablets and Tulsi capsules). HPTLC on silica gel with toluene - ethyl acetate - acetic acid 30:3:1. Detection with anisaldehyde in sulphuric acid reagent followed by heating in an oven at 110 °C. Quantitative determination by absorbance measurement at 580 nm. Linearity of the detector response was given in the range of 40 - 280 ng. LOD was 8 ng. The correlation coefficient obtained from linearity was 0.9985. The standard error was 26.511. The mean assay values of ursolic acid wa found to be 3.485 mg/g, 0.553 mg/g and 3.221 mg/g in tulsi ghan tablets, tulsi capsule and tulsi leaves respectively.
Chromatographia 63 (3-4), 209-213 (2006). HPTLC of valerenic acid in Valeriana jatamansi and Valeriana officinalis on silica gel with hexane - ethyl acetate - acetic acid 160:40:1. Detection with anisaldehyde-sulphuric acid reagent. Quantitative determination by absorbance measurement at 700 nm. The calibration curves were linear in the range of 500 ng - 2.5 µg/zone.
Chem. Pharm. Bull. 53, 691-693 (2005). HPTLC of trans-resveratrol in the roots of Polygonum cuspidatum and in dosage forms on silica gel with chloroform – ethyl acetate – formic acid 25:10:1. Quantitative determination by absorbance measurement at 313 nm. Linearity of determination of trans-resveratrol is between 0.5 and 3.0 µg with a correlation coefficient of 0.9989. LOD is 9 ng, and LOQ is 27 ng. The average percentage recovery is 99.9 - 100.7 %.
LC-GC Europe, The Applications 19, (2006). HPTLC of Actaea racemosa (black cohosh) extracts on silica gel with toluene - ethyl formate - formic acid 5:3:2 with chamber saturation for 20 min and at a relative humidity of 5 % (automatic development chamber ADC2 with molecular sieve). Detection by dipping in sulfuric acid reagent (20 mL of sulfuric acid in 180 mL of methanol) followed by heating at 100 °C for 5 min. Evaluation under daylight and under UV 254 and 366 nm. The method is specific for identification of black cohosh and for discrimination from different species of common adulterants.
