Abstract No. F-260, 61st IPC (2009). HPTLC of cefixime and cloxacillin on silica gel, prewashed with methanol, with n-butanol - methanol - water - formic acid 80:60:40:3. The hRf values were 28 and 45 for cefixime and cloxacillin, respectively. Quantitative determination by absorbance measurement at 293 nm for cefixime and 343 nm for cloxacillin. The linearity range was 150-600 ng/band for both compounds.
Abstract No. F-253, 61st IPC (2009). HPTLC of tenofovir and emtricitabine on silica gel with toluene - methanol - ethyl acetate - acetic acid 40:20:50:1. Quantitative determination by absorbance measurement at 273 nm. The hRf value was 52 for tenofovir and 40 for emtricitabine. Linearity of tenofovir and emtricitabine was in the range of 120-600 ng/spot and 80-560 ng/spot, respectively. The recovery was 99.9 and 99.5 % for tenofovir and emtricitabine, respectively.
J. Planar Chromatogr. 22, 277-281 (2009). HPTLC of racecadotril (2-{2(acetylsulfanylmethyl)-3-phenylpropanoyl}amino acetic acid benzyl ester) and its degradation products in the bulk drug and in a pharmaceutical formulation on silica gel with n-hexane - ethyl acetate 7:3 in a twin trough chamber saturated for 30 min. Quantitative determination by absorbance measurement at 230 nm. The limit of detection and quantification was 50 and 100 ng/band, respectively.
Abstract No. F-256, 61st IPC (2009). HPTLC of cefixime trihydrate and erdosteine in combined capsule dosage form on silica gel with ethyl acetate - acetone - methanol - water 15:5:5:3. Quantitative determination by absorbance measurement at 235 nm. The calibration curve was linear between 100 and 500 ng/band for cefixime and 150 to 750 ng/band for erdosteine. The limit of detection and quantification for cefixime was 0.37 µg/mL and 1.14 µg/mL, respectively and for erdosteine 0.33 µg/mL and 1.04 µg/mL, respectively.
J. Planar Chromatogr. 23, 129-133 (2010). TLC of glicazide and glipizide on RP18 silica gel with 60 % acetonitrile in pH 2.3 phosphate buffer in an unsaturated horizontal chambers at room temperature. Detection and quantitative determination by absorbance measurement at 215 nm. Linearity was in the range of 0.8-1.8 µg/zone for both drugs and the correlation coefficients r were 0.998 for gliazide (hRf 38) and 0.993 for glipizide (hRf 51). LOD and LOQ were 50 and 200 ng/zone, respectively, for glicazide and 60 and 300 ng/zone for glipizide.
Abstract No. F-234 61st IPC (2009). A stability-indicating HPTLC method is reported for estimation of diacerein in the presence of its degradation products. HPTLC on silica gel with toluene - ethyl acetate - formic acid 50:30:1. The hRf value of diacerein was 39. Densitometric analysis at 254 nm. The method was found to be linear in the range of 100-600 ng/band. The method was validated regarding stability. The sample was subjected to different stress conditions (acid/base hydrolysis, oxidation, photolysis, thermal) and showed extensive degradation in alkaline medium and mild degradation under acidic and oxidative conditions. The method allowed separation of diacerein from different degradation products.
Indian J. Pharma. Educ. Res. 44(4), 341-344 (2010). HPTLC of silica gel with toluene - ethyl acetate - methanol - formic acid 5:16:21. The hRf value was 51. Densitometric evaluation at 220 nm. The method was linear in the range of 300-1800 ng/band. The sample was subjected to different stress conditions (acid, base, oxidative, thermal, and photolytic). Degradation products were well separated from trandolapril, therefore the method can be used for stability studies.
J. Planar Chromatogr. 24, 35-39 (2011). HPTLC of olmesartan medoxomil (OLM) and hydrochlorothiazide (HTZ) on silica gel with chloroform - methanol - formic acid 16:3:1 in a chamber saturated for 1 h. Detection under UV light at 254 nm. Quantitative determination by densitometry at 260 nm for olmesartan medoxomil and 272 nm for hydrochlorothiazide. Linearity was between 0.05-1 mg/mL. Average recovery was 100.3 % and 99.9 % for OLM and HTZ, respectively. The LOD was 138 and 137 ng/zone for OLM and HTZ, respectively, and the LOQ was 459 and 456 ng/zone for OLM and HTZ, respectively. The intra-day and inter-day precision (%RSD, n = 9) was 1.2 and 1.4 % for OLM and 1.1 and 1.3 % for HTZ.
