J. of Chromatogr. A 1218 (33), 5693-5704 (2011) A micro-TLC platform for the fast analysis of low-molecular mass compounds from spirulina samples was developed. The target compounds were extracted with methanol, acetone or tetrahydrofuran. HPTLC on RP-18W with acetone - n-hexane 3:7 in an unsaturated chamber using a temperature controlled micro-planar chromatographic device based on a horizontal chamber. Detection under visible light before and after exposure to iodine vapor. Pictures of the chromatograms were acquired with an office scanner and digitalized. The quantitative data was analyzed using cluster analysis and principal components analysis. With this method it was possible to distinguish genuine spirulina and non-spirulina samples as well as fresh and expired commercial products.
International Journal of PharmTech Research 3(2), 909-918 (2011). TLC of paracetamol, aceclofenac and rabeprazole on silica gel (prewashed with methanol) with ethyl acetate - methanol - glacial acetic acid 90:10:1 with chamber saturation for 20 min. The hRf value of paracetamol, aceclofenac and rabeprazole was 79, 63 and 39. Quantitative determination by densitometry in absorbance mode at 275 nm. The method was linear in the range of 100-500 ng/band for paracetamol, 20-100 ng/ band for aceclofenac, and 2-10 ng/band for rabeprazole. The recovery was between 99.2-101.0 %.
Preparative Biochemistry and Biotechnology 40, 337-346 (2010). TLC of dexrabeprazole (DEX) and domperidone (DOM) in combined dosage form on silica gel with acetone - toluene - methanol 9:9:1. Quantitative evaluation by absorbance measurement at 285 nm. The hRf of DEX and DOM was 49 and 24, respectively. The linearity range for DEX was 50-350 ng/band (r=9960) and for DOM 100-700 ng/band (r=9982).
J. Liq. Chromatogr. Relat. Technol. 34, 2606-2620 (2011). HPTLC of dexketoprofen trometamol in pharmaceutical formulations on silica gel with toluene - ethyl acetate 3:1 + 1 drop glacial acetic acid. Quantitative determination by absorbance measurement at 255 nm. The hRf of 1 was 45. Linearity was 20-120 ng/zone. LOD and LOQ were found to be 5 and 10 ng/zone. Repeatability and intermediate precision (%RSD, n = 6) were below 2 %. Recovery (by standard addition) ranged between 98.8 and 99.3 %. The HPTLC method was suitable to determine the purity of the drug available from various sources by detecting the related impurities.
J. Planar Chromatogr. 24, 77-81 (2011). HPTLC of belleric acid on silica gel, prewashed with methanol, with toluene - ethyl acetate - methanol - formic acid 15:15:7:1 in a saturated chamber at 22 °C and 65 % relative humidity. Quantitative determination by absorbance measurement at 205 nm. Average recovery was 98.7-100.9 %. Linearity was between 250 and 1250 ng/zone. Repeatability and intermediate precision (%RSD) were 1.2 and 1.5 %, respectively. LOD and LOQ were 49 and 148 ng/zone, respectively. The hRf value of belleric acid was 35.
J. Planar Chromatogr. 24, 312-315 (2011) HPTLC of methanolic extracts of L. tibetica on silica gel (prewashed with methanol) with hexane - ethyl acetate - formic acid 12:7:1 for three furofuranolignans (sylvatesmin, (+)-piperrtol, horsfieldin), beta-sitosterol, and oleanolic acid, and with chloroform - methanol - water - formic acid 70:25:4:2 for four furofuranolignans (phillyrin, tibeticoside A, lantibeside C, and lantibeside), verbascoside and isoverbascoside in a twin-trough chamber with saturation for 20 min. Detection by immersion in ethanolic sulfuric acid for 2 s followed by heating for 5 min at 100 °C. The hRf values were 17, 25, 29, 51, 60, 70, 66, 49, 46, 19, and 21 for sylvatesmin, (+)-piperrtol, horsfieldin, oleanolic acid, beta-sitosterol, phyllirin, tibeticoside A, lantibeside C, lantiboside, verbascoside and isoverbascoside, respectively.
J. Planar Chromatogr. 25, 344-348 (2012). HPTLC of two oil-soluble sunscreens, namely avobenzone (1) and octyl salicylate (2) and a water-soluble sunscreen, namely phenylbenzimidazol sulfonic acid (3) on silica gel with cyclohexane - diethyl ether 5:1 for (1) and (2) and ethyl acetate - ethanol - water 14:7:6 for (3). Quantitative determination by absorbance measurement at 300 nm for (2) and (3), and 360 nm for (1). Limits of detection and quantification were found to be 30 and 80 ng/zone for (1), and 20 and 60 ng/zone for both (2) and (3).
J. Planar Chromatogr. 25, 542-547 (2012). HPTLC of tartrazine in mustard on silica gel with isopropyl alcohol - ammonia 7:3. Quantitative determination by absorbance measurement at 425 nm (1) and by digital processing using a TLC scanner at an optical resolution of 300 dpi in visible mode followed by image digitalization (2). The hRf of tartrazine was 61. Linearity was in the range of 32-878 ng/zone using (1) and 92-600 ng/zone using (2). Limits of detection and quantification were 5 and 11 ng/zone using (1) and 51 and 74 ng/zone using (2). Average recovery with both methods was greater than 100 %. Lower contents of tartrazine in mustard samples were determined when TLC image processing was applied for quantification probably due to poor sensibility of calibration with this method.
