Chem. 18(1), 667-672 (2006). HPTLC of mefenamic acid and drotaverine HCl in tablets on silica gel with methanol - toluene - triethylamine 10:75:2. Quantitative determination by absorbance measurement at 241 nm. The hRf values were 31 and 47 for mefenamic acid and drotaverine HCl, respectively. The method was validated in terms of accuracy, precision, specificity, ruggedness. Linearity was between 3800 and 8400 ng for mefenamic acid and 1200 and 2700 ng for drotaverine HCl. The recovery (by standard addition method) was in the range of 99.1-100.9 % for both compounds. The method could be used for routine analysis of these compounds and their combined dosage form.
Ind. J. Pharm. Sci. 70(3), 386-390 (2008). HPTLC for the simultaneous estimation of ondansetron combinations in solid dosage form with omeprazole and rabeprazole, on silica gel with dichloromethane - methanol 9:1. Quantitative determination by absorbance measurement at 309 nm for combinations of ondansetron with omeprazole and at 294 nm for ondansetron with rabeprazole. The hRf value of ondansetron and omeprazole was 42 and 54, respectively, while for ondansetron and rabeprazole hRF values were 41 and 51 respectively. Linearity was between 100 and 500 ng/spot for three drugs. The method can be employed for routine quality control of such formulation.
J. Liq. Chromatogr. Relat. Technol. 31, 1892-1902 (2008). HPTLC of hydrochlorothiazide, walsartan, kandesartan, and enalapril on silica gel after chamber saturation using ethyl acetate - tetrahydrofuran - acetic acid 16:4:1 (for kandesartan and walsartan present together with hydrochlorothiazide) and 1-butanol - acetic acid - water 12:3:5 (for enalapril and hydrochlorothiazide). Quantitative determination by absorbance measurement at 252 nm for walsartan and kandesartan, at 274 nm for hydrochlorothiazide and at 208 nm for enalapril. The method was of high sensitivity and specific to analyte constituents.
Phosphorus, Sulfur Silicon Relat. Elem. 184, 1139-1148 (2009). The new TLC system for sulfide ions detection is based on the use of 2,4,6-triphenylpyrylium salts as pre-chromatographic derivatization reagents. The cations L1 (2,4,6-triphenylpyrylium) or LN1 (4-[p-(N,N-dimethylamino) phenyl]-2,6-diphenylpyrylium) were used in the derivatization reactions in a tube or directly on the TLC plate before the developing step. TLC of L1 on silica gel with methanol – dichloromethane 1:5. TLC of LN1 on cellulose with phosphoric buffer (pH 6.0) – acetonitrile – 1,4-dioxane 4:2:1. The detection procedure allows selective and sensitive detection for sulfide anions at several dozen pmol/spot.
Phytochem. Anal. 20, 253-255 (2009). HPTLC of saponins in the tea seed meal of Camellia oleifera on silica gel with ethyl acetate – methanol – water 4:2:1. Quantitative determination by absorbance measurement at 214 nm. The hRf value of tea saponin was 40 and selectivity regarding matrix was given. The correlation coefficient was 0.9978 and the relative standard deviation 1.6 %. Linearity was between 0.9 and 22.2 µg/spot. The limit of detection and quantification was 870 ng and 2900 ng/spot, respectively.
Abstract No. 9147, IHCB (2009). HPTLC of quercetin in methanolic leaf extracts of Viola odorata on silica gel with ethyl acetate - formic acid - glacial acetic acid - water 100:11:11:26. Quantitative determination by absorbance measurement at 366/>400 nm for quantification. The extract contained 0.36 % quercetin.
Abstract No. 0983, IHCB (2009). HPTLC of mahanimbine (a carbazole alkaloid isolated from Murraya koenigi) on silica gel with petroleum ether - chloroform 13:7. The hRf value of mahanimbine was 60. Quantitative determination by absorbance measurement at 254 nm. The method was linear in the concentration range of 50-250 ng/spot. Enzyme inhibition activity of methanol, petroleum ether, and chloroform exctracts of the plant and of mahanimbine was evaluated using galantamine as standard inhibitor of the enzyme.
Chromatographia 69 (5-6), 597-599 (2009). TLC of karanjin in the seeds of Pongamia pinnata on silica gel with toluene - ethyl acetate 7:3. Quantitative determination by absorbance measurement at 260 nm. The limit of detection was 100 ng, linearity was 50 - 300 ng. Four samples of P. pinnata from different geographical locations were screened for their karanjin content.
