Biomed. Chromatogr. 6, 67-71 (1992). TLC of anti-ganglioside antibodies on silica with chloroform - methanol - 0.02% aqueous CaCl2 60:40:9. Detection by spraying with resorcinol - hydrochloric acid solution and heating at 110°C for 15 min. Transfer of gangliosides from the layer to hydrophobic polyvinylidene difluoride membranes, which is suitable for immunostaining.

Codex Alimentarius Hungaricus, 3-1-80, 891 (1997). TLC on silica with toluene - hexane 9:1. Detection with 2,7-dichloro-fluoresceine reagent.

Anal. Biochem. 269, 304-311 (1999). HPTLC of total urinary lipids on silica gel with chloroform - methanol - water 65:25:4. The chromatogram was first sprayed with primuline, and sphingomyelin was determined fluorometrically at 365 nm/>400 nm. Subsequently, sulfatides were stained with azure A or orcinol. Densitometry in reflection mode at 610 or 546 nm, respectively.

60th Indian Pharmaceutical Congress PA-206, (2008). HPTLC of (-)hydroxy citric acid in fruits of Garcina Gummigutta on silica gel with n-propanol - water - acetic acid 50:50:1 in a twin-trough chamber saturated for 10 min. Quantitative determination by absorbance measurement at 210 nm. The method was linear in the range of 100-1000 ng/spot. Recovery was 99.8-100.9 %.

International Seminar on Herbal Drug Research, PN-064 (2009). HPTLC of gallic acid as marker compound in triphala fast dispersable tablets on silica gel with ethyl acetate - toluene - methanol - glacial acetic acid 75:20:3:2. Results from HPLC analysis were comparable. The method was suitable for routine quality control of dispersable tablets formulation.

Indian Drugs 47(6), 59-61 (2010). HPTLC of gallic acid in bark powder of Terminalia crenulata (Combretaceae) on silica gel with toluene - ethyl acetate - formic acid - methanol 60:60:16:4 with chamber saturation for 30 min. Densitometric evaluation at 254 nm. The method was linear in the range of 200-1200 ng/band. Samples extracted with different solvents were compared. Both alcoholic and water extracts were found to contain gallic acid where as it was absent in the chloroform extract.

Scholars Research Library 2(3), 163-167 (20100. TLC on silica gel with n-butanol - water - methanol - ammonia 8:1:1:2 with chamber saturation for 10 min. The hRf value was 33 for gatifloxacin and 89 ambroxol HCl. The method was linear in the range of 100-600 ng/band for gatifloxacin and 12.5-62.5 ng/band for ambroxol HCI. The recovery was 99.3-100.3 %. Densitometric evaluation at 310 nm.

62nd Indian Pharmaceutical Congress Abstract No. F-332 (2010). TLC of ramipril and hydrochlorothiazide on silica gel with ethyl acetate – methanol – chloroform – glacial acetic acid 11:3:7:2. The hRf values were 28 and 49 for ramipril and hydrochlorothiazide,respectively. Quantitative determination by absorbance measurement at 210 nm. The method was linear in the range of 500-1900 ng/band for both compounds. The recovery was 98-102 % for both drugs. The results were comparable when the sample was analysed by a dual wave-length method. The proposed method can be used for analysis of formulation without any interference from excipients.
