Evaluation of the fingerprint profile at 254 nm and after derivatization at 366 nm by spraying with anisaldehyde-sulfuric acid reagent followed by heating at 110 °C.
Research Journal of Pharmaceutical, Biological and Chemical science 2(12), 389-396 (2011). TLC of a polyherbal formulation containing Mucuna pruriens with L-dopa as biological marker on silica gel with n-butanol - water - glacial acetic acid 4:1:1 with chamber saturation for 30 min. Detection by dipping in a 0.5 % solution of ninhydrin in ethanol, followed by heating at 120 °C for 2 min. Quantitative determination of L-dopa by densitometry in absorbance mode at 520 nm. The hRf value of L-dopa was 37. Linearity was given in the range of 600-1400 ng/zone.
J. Planar Chromatogr. 24, 281-289 (2011). TLC of tartrazine (E 102), quinoline yellow (E 104), azorubin (E 122), ponceau 4R (E 124), allura red AC (E129), patent blue V (E 131), and brilliant blue FCF (E133) on RP-18 or cyano phase with methanol - acetate or citric buffer containing diethylamine or octane-1-sulfonic acid sodium salt.

Research Journal of Pharmaceutical, Biological and Chemical Sciences 2(1), 108-110 (2011). TLC of flurbiprofen in raw material and tablet dosage form on silica gel with chloroform - methanol - 25 % ammonia 45:5:3. Quantitative evaluation by absorbance measurement at 247 nm. The method was linear in the range of 50-600 ng/band. The sample was subjected to different stress conditions and all the degradation products were well resolved from the main compound. The method can therefore be used for stability studies.
