J. Liq. Chromatogr. Relat. Technol. 33, 936-947 (2010). TLC of essential oils (multicomponent mixtures of mono-, di, tri-, and sesquiterpenes) from Salvia species at 22 +/- 1 °C and at -10 +/- 0.5 °C on silica gel with toluene - ethyl acetate 19:1 in sandwich chambers saturated with mobile phase for 15 min. Quantitative absorbance measurement at 340 nm. Also preparative TLC after bandwise application at -10 +/-2 °C in saturated sandwich chambers. After extraction of the separated bands GC with mass spectrometric detection was performed. Low temperature TLC densitometry can successfully be used for fingerprinting of essential oils contained in the different sage species.
Eurasian J. Anal. Chem. 4(1), 87-97 (2009). HPTLC of rabeprazole sodium on silica gel with acetone - water 7:30. The hRf value was 45. Densitometric quantification at 284 nm. Linearity was in the range of 400-2400 ng/band. The recovery was 99.6-101.4 %. The sample was subjected to forced degradation (acid, alkali, oxidative, thermal, photolytic). The degradation products were well separated from the main compound and the method is suitable for stability studies.
Pharmaceutical Methods 1(1), 39-43 (2010). TLC on silica gel with acetonitrile - chloroform 5:6. The hRf value of irbesartan was 27 and of hydrochlorothiazide 45. Densitometric evaluation at 270 nm. The method was linear in the range of 200-1000 ng/band for irbesartan and 200-600 ng/band for hydrochlorothiazide. The drug was subjected to different stress conditions (acid, base, oxidation, thermal, photolytic). All the degradation product were well resolved from the main drug. The proposed method is stability-indicating and suitable for routine analysis of fixed dose formulation in presence of degradation products.
Talanta, 80 (5), 2007-2015 (2010). Presentation of a method for determination of oxybutynin hydrochloride (OX) in presence of its degradation product and additives in its pharmaceutical formulations. UV spectrophotometry using the first derivative of ratio spectra and measurment at 216 nm. Chemometric analysis using principal component regression and partial least-squares. HPTLC of OX and its degradation products methylparaben and propylparaben on silica gel with chloroform - methanol - ammonia - triethylamine 500:15:2.5:1. Quantitative determination by densitometry at 220 nm. Comparison of the results obtained with all three methods showed no significant differences.
CBS 105, 2-4 (2010). TLC and HPTLC of reaction samples from small molecule lead development, on silica gel with mixtures of methanol and dichloromethane/ethyl acetate or ethyl acetate and heptane/cyclohexane (ratios depending on the compound mixtures). Detection with primuline or berberine reagent. Direct elution into the MS with the TLC-MS interface. Substances not detected by DAD can successfully be measured by ELSD detection coupled to TLC.
62nd Indian Pharmaceutical Congress Abstract No. F-233 (2010). TLC of metoprolol and ramipril on silica gel with methanol – toluene – ethyl acetate – ammonia 25:30:50:7. Quantitative determination by absorbance measurement at 209 nm. The hRf values of metoprolol and ramipril were 67 and 37, respectively. The reliability of the method was assessed by evaluation of linearity (2-12 µg/band for metoprolol and 0.2-1.2 µg/band for ramipril).
62nd Indian Pharmaceutical Congress Abstract No. F-264 (2010). TLC of lamivudine, zidovudine and nevirapine on silica gel with chloroform – methanol 9:1. The hRf values were 7, 46 and 77 for lamivudine, zidovudine and nevirapine, respectively. Quantitative determination by absorbance measurement at 265 nm. The method was linear in the range of 90-210 µg/band, 180-240 µg/band and 120-280 µg/band for lamivudine, zidovudine and nevirapine respectively.
62nd Indian Pharmaceutical Congress Abstract No. F-381 (2010). TLC of citicoline sodium on silica gel with chloroform – methanol – water 3:7:3. The hRf value was 53. Quantitative determination by absorbance measurement at 280 nm. The results of the method were comparable with the results of a RP-HPLC method.
