Abstract No. 9192, IHCB (2009). HPTLC of betulinic acid in hydro alcoholic extracts of Nelumbo nucifera rhizome and seed, on silica gel with chloroform - methanol - formic acid 49:1:1. Detection by spraying with anisaldehyde reagent. Quantitative determination by absorbance measurement at 420 nm. The method was linear in the range of 2-10 ng/spot, recovery was 98.1-98.4 %.
J. Chromatogr. A 1216 (42), 7102-7107 (2009). HPTLC of co-trimoxazole tablets (combination of sulfamethoxazole and trimethoprim) on silica gel with toluene – ethyl acetate – methanol 100:57:43. Detection under UV 254 nm. The hRf values were 30 and 61 for trimethoprime and sulfamethoxazole, respectively. Quantification by densitometry at UV 254 nm. Cochran's criterion test indicated homoscedasticity of variances for the calibration data. The F-tests for lack-of-fit indicated that straight lines were adequate to describe the relationship between spot areas and concentrations for each compound. Repeatability and precision (%RSD) was 1.0 and 0.8 % for sulfamethoxazole as well as 1.3 % and 1.6 % for trimethoprim, respectively. Recovery was 99.0 % and 99.7 % for sulfamethoxazole and trimethoprim, respectively.
Abstract No. F-347, 61st IPC (2009). HPTLC of gatifloxacin and ornidazole on silica gel with dichloromethane - methanol - 25 % ammonia 95:10:3. The hRf value was 16 and 60 for gatifloxacin and ornidazole, respectively. Quantitative determination by absorbance measurement at 302 nm. The method was linear in the range of 20-200 ng/band for gatifloxacin and 50-500 ng/band for ornidazole. Recovery was between 100.4 and 101.9 for both drugs.
60th Indian Pharmaceutical Congress PG-244 (2008). HPTLC of Centella asiatica extract with asiaticoside as marker on silica gel with chloroform - glacial acetic acid - methanol - water 15:8:3:2 with chamber saturation. Detection by spraying with anisaldehyde reagent, followed by heating in oven and immediate quantitative determination by absorbance measurement at 607 nm. The hRf value of asiaticoside was 81. Linearity was in the range of 0.96-3.36 µg/spot. Hydroalcoholic extracts contained approx. 3.2 % of asiaticoside.
J. Pharm. Biomed. Anal. 46, 391-394 (2008). TLC of conessine on silica gel with toluene - ethyl acetate - diethyl amine 13:5:2 in a twin trough chamber saturated at 25 °C. Detection by treatment with modified Dragendorff’s reagent. Quantitative determination by absorbance measurement at 520 nm. The hRf value of conessine was 82. Linearity was in the range of 1-10 µg/zone with a correlation coefficient of 0.9998 via peak area.
Abstract No. F-244, 61st IPC (2009). HPTLC of rabeprazole and itopride on silica gel with ethyl acetate - methanol - benzene - chloroform 2:4:3:1. The hRf value was 42 and 61 for rabeprazole and itopride, respectively. Quantitative determination by absorbance measurement at 276 nm. The method was linear in the range of 200-300 ng/band for rabeprazole and 1500-2250 ng/band for itopride.
Abstract No. F-274, 61st IPC (2009). HPTLC of ondansetron HCl on silica gel with chloroform - ethyl acetate - methanol - 25 % ammonia 90:50:40:1. The hRf value was 52. Quantitative determination by absorbance measurement at 254 nm. The method was linear in the range of 100-1400 ng/band. Recovery was 99.3 %.
Abstract No. F-267, 61st IPC (2009). HPTLC of camylofin dihydrochloride on silica gel with chloroform - ethyl acetate - methanol - 25 % ammonia 50:30:20:1. Quantitative determination by absorbance measurement at 215 nm. Linearity was in the range of 1.5-7.5 µg/band. The proposed method is suitable for routine quality control of bulk drug and tablets.
