Research J. Pharm. and Tech. 3(3), 825-827 (2010). TLC on silica gel (plates pre-washed with methanol) with chloroform - methanol 4:1. The hRf value of aceclofenac was 38 and of diacerein 66. Densitometric evaluation at 256 nm. The linearity range was 10-50 µg/band for aceclofenac and 5-25 µg/band for diacerein. The recovery was in the range of 99.3-101.8 % for both compounds. The method was suitable for routine quality control of combined dosage forms without any interference from the excipients.
J. Liq. Chromatogr. Relat. Technol. 33, 1047-1057 (2010). TLC of R-beta-hydroxybutyric acid on silica gel pre-washed with methanol - water 9:1 and impregnated by dipping for 2 s in a 0.05 mol/L water - methanol solution of copper acetate. TLC was carried out at 22 +/- 1 °C with dioxane - water 9:1. Detection by spraying with 5 % sulfuric acid in ethanol and heating at 100-110 °C for 10 min. Quantitative determination by absorbance measurement at 326 nm. It was experimentally established that R-beta-hydroxybutyric acid can undergo oscillatory chiral conversion.
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.
Asian Journal of Chemistry 22(8), 5951-5955 (2010). TLC on silica gel with cyclohexane - methanol - ethyl acetate - 25 % ammonia 10:3:6:1. The hRf value was 7 for atenolol and 69 for nifedipine. Densitometric evaluation at 230 nm. The linearity was in the range of 3-21 µg/band for atenolol and 1.2-8.4 µg/band for nefidipine. The recovery was 100.7 % for both drugs. The method was found suitable for analysis of the combined dosage form of atenolol and nefidipine without interference of excipients.
Research Journal Pharm and Tech. 2(4),746-748 (2009). A validated HPTLC method is reported for simultaneous estimation of nebivolol hydrochloride and valsartan in combined dosage form. HPTLC on silica gel with ethyl acetate - methanol - 25 % ammonia. The hRf value of valsartan was 27 and of nebivolol 75.The method was linear in the range of 800-2400 ng/band for nebivolol and 200-1000 ng/band for valsartan. Densitometric quantification at 280 nm. The method was found suitable for routine quality control of the combined dosage form.
Chinese J. Chromatogr. 26 (1), 50-55 (2008). TLC of some endophytic fungi isolated by column chromatography from selected medicinal plants on silica gel plates with 1) chloroform - methanol 7:1, 2) chloroform - acetonitrile 7:3, 3) ethyl acetate - 2-propanol 19:1, 4) methylene chloride - tetrahydrofuran 3:1, 5) methylene chloride - methanol - dimethylformamide 90:9:1. Detection by spraying with 1 % vanillin sulfuric acid reagent after gentle heating. Also HPTLC on silica gel with chloroform - methanol 9:1. Detection by densitometry at 254 nm and 366 nm. If taxol was present, derivatization by spraying with 1 % vanillin sulfuric acid reagent and heating for 2 min, then detection under UV 366 nm and white light. Only 13 fungal species produced taxol in the artificial culture medium of the 20 screened fungi.
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. Chromatogr. A 1218 (19), 2754-2774 (2011). HPTLC for lipid analysis is particularly useful for smaller, apolar compounds and offers some advantages over HPLC. Description of stationary phases, solvent systems and detection methods for the individual lipid classes (cholesterol and its derivates, glycerides, sphingo- and glycolipids, phospholipids). In comparison with common staining methods the combination of HPTLC and mass spectrometric detection methods is a very powerful method to investigate the identities of the HPTLC zones in detail.
