International Journal of ChemTech Research 1(4), 1129-1135 (2009) The marker compound was first isolated by column chromatography over silica gel by elution with toluene - ethyl acetate 17:3. TLC of ethanolic extracts of Syzgium cumini seed on silica gel with toluene - ethyl acetate 17:3. The hRf value of the marker compound was 50. Densitometric evaluation in fluorescence mode at 366 nm. The method was linear in the range of 1-5 µg/band. The extract of the powdered sample contained 7.4 % of the marker compound.
International Journal of Pharma World Research 1(2) (2010). A validated stability indicating assay method is described for estimation of voglibose in bulk and dosage formulation. TLC on pre-washed silica gel plates with acetonitrile - methanol - 25 % ammonia 150:40:1. The hRf value of voglibose was 66. Densitometric evaluation at 284 nm. The method was linear in the range of 100-450 ng/band. The average recovery was 101.4 %.
Journal of Pharmacy Research 2(1), 189-195 (2009). A validated HPTLC method has been developed for simultaneous estimation of valdecoxib and tizanidine in dosage form. HPTLC on silica gel with toluene - methanol - ethyl acetate 2:2:1. The compounds were well separated as compact bands. The method was linear in the range of 10-100 ng/band for tizanidine and 100-1000 ng/band for valdecoxib. The recovery was in the range of 99.3-101.2 %. Densitometric quantification at 254 nm. The method is suitable for quality control of combined dosage form.
J. Chromatogr. Sci. 49, 129-135 (2011). TLC of hydrochlorothiazide (HCT), spironolactone (SPR) and their impurities and degradation products on silica gel with ethyl acetate - chloroform - formic acid - triethyl amine 70:30:1:1. Quantification by densitometry. The different method parameters were optimized for maximum separation. The method was applied for determination of HCT and SPR in commercial tablets. Statistical comparison with the also performed HPLC method showed that there is no significant difference in the performance of the methods.
Asian Journal of Chemistry 22(6), 4209-4213 (2010). HPTLC of beta-blockers on silica gel with toluene - ethyl acetate - acetone - 25 % ammonia 10:20:20:1. The method was applied to biological samples (urine and blood). The drugs were extracted from biological samples by liquid-liquid extraction. Detection at 254 nm. The corresponding separated spots were scraped from the plate, extracted with methanol and analyzed by mass spectrometry. Finally the identity was confirmed by comparing the spectra with a data library. The proposed HPTLC method coupled with MS is very sensitive and highly suitable for biological samples.
J. Chromatogr. A 1218 (19), 2732-2736 (2011). A review on the sustainability and robust advantages of TLC and the parameters which are critical to the successful performance of product quality assessments in resource limited areas including field applications. The training required for successful performance of HPTLC assessments is much lower than that of other technologies with comparable reproducibility such as HPLC, because of the robustness and ease of use for HPTLC. Presentation of some of the successful applications of planar chromatography in resource limited countries. In practice in finished pharmaceutical products there are generally few active ingredients which are assessed making the HPTLC adequate for these analyses.
CBS 106, 7-10 (2011). HPTLC of sucralose on silica gel (pre-washed by development with methanol, followed by drying at 100 °C for 15 min) with isopropyl acetate – methanol – water 15:3:1 up to 60 mm (migration time 15 min). Detection by dipping in aniline diphenylamine o-phosphoric acid reagent followed by heating at 120 °C for 20 min, evaluation under white light and UV 366 nm. Quantitative determination by absorbance measurement at 400 nm. Via the TLC-MS Interface the respective zones were eluted and transferred into a single-quadrupole mass spectrometer. Electrospray ionization mass spectra were recorded in full scan mode. The recovery of sucralose in drinking water was 84 ± 7 % (n=3). The limit of detection was 6 ng/band. The calibration curve (10-300 ng/band, r=0.9999, 1.3 %RSD) was suited to analyze sucralose at concentrations of 0.1-5 µg/L.
62nd Indian Pharmaceutical Congress Abstract No. F-335 (2010). TLC of ampicillin and dicloxacillin on silica gel with n-butanol – water – formic acid 63:6:4. Quantitative determination by absorbance measurement at 220 nm. The hRf values of ampicillin and dicloxacillin were 85 and 69 respectively. The linearity was in the range of 1-6 µg/zone for both ampicillin and dicloxacillin. The recovery for ampicillin was 98.5-101.9 % and that for dicloxacillin was 98.3-101.3 %.
