J. Chromatogr. B 823 (2), 152-157 (2005). HPTLC of lamotrigine (extracted from serum by ethyl acetate) on silica with toluene - acetone - ammonia 14:6:1. Densitometric measurement at 312 nm, hRf of lamotrigine at 54. The analytical method has excellent linearity (r = 0.998) in the range of 20–300 ng/spot. This assay range is adequate for analyzing human serum, as it corresponds to lamotrigine concentrations measured in human serum from epileptic patients. The method was validated for sensitivity, selectivity, extraction efficiency, accuracy and intra and inter-day reproducibility. The limit of detection and limit of quantification were found to be 6.4 and 10.2 ng, respectively. Good accuracy and high precision (CV) is reported, i.e. in the range of 92.1-97.1 % and 0.5-2.6 % respectively. The method was applied for determination of serum lamotrigine levels in epileptic patients and in pharmacokinetic study of lamotrigine administered orally to rabbits.

J. Liq. Chromatogr. Relat. Technol. 30, 2891-2902 (2007). HPTLC of L-glutamate and L-aspartate on silica gel by double elution with n-butanol - acetic acid - water 13:3:5 in a chamber saturated for 3 h. Detection by spraying with 0.2 % ninhydrin solution in acetone. Quantitative determination by absorbance measurement at 486 nm.

Encyclopedia of Chromatography Third Edition 1, 2319-2322 (2009). The author describes the techniques and instruments for the detection and quantification of radiolabeled substances in thin-layer radiochromatography (TLRC) or radio-TLC. In detail, film autoradiography, liquid scintillation counting (LSC), storage phosphor imaging and in situ radioactivity scanning are described. The instruments for these methods are highly automated providing significant advantages in radiopharmaceutical purity determination, metabolism studies and many other investigations.

Planta Med. 75, 132-136 (2009). Analytical and preparative TLC of 3’-hydroxy-4’,5,6,7-tetramethoxyflavone, 3’,5-dihydroxy-4’,6,7-trimethoxy-flavone (eupatorin), and 3’,4’,5,6,7-pentamethoxyflavonene (sinensetin) and methanolic plant extracts of Orthosiphon stamineus on silica gel with chloroform - ethyl acetate 7:3, and chloroform - ethyl acetate - acetic acid 30:70:1. Detection by spraying with anisaldehyde-sulfuric acid followed by heating.

J. Planar Chromatogr. 28, 126-132 (2015). TLC of 17 morphine derivatives on RP phase with 3 different mobile phases, (1) methanol - 0.02 M ammonium hydroxide, (2) methanol - 0.7 M ammonium hydroxide, and (3) methanol - 0.02 M acetic acid. In each case, the individual mobile phases contained 30-90 % (v/v; in 10 % increments) of methanol as an organic modifier. Detection by absorbance measurement at 254 nm. RP-TLC can be used for the characterization of the lipophilicity of semisynthetic derivatives of morphine.
