Chinese J. Trad. Pat. Med. (Zhongchengyao) 26 (9), App.12-14 (2004). TLC on silica gel with 1) n-butanol - glacial - water 19:5:5; 2) chloroform - methanol - glacial acetic acid - 17:2:1; 3) two fold development with benzene - acetone 9:1. Detection 1) by spraying with ninhydrin solution and heating at 105 ºC; 2) by spraying with 5 % vanillin solution and heating; 3) by spraying with a solution of 8 % vanillin in ethanol - H2SO4, and heating at 105 ºC. Identification by fingerprint technique. Quantification of phyllyrin by densitometry at 280 nm. The quantitative procedure is validated by investigating its linearity (1 - 5 µg/spot, r = 0.9998); precision (RSD = 0.36 % n = 5); repeatability (RSD = 2.92 % n = 5) and standard addition recovery (99.6 %, RSD = 2.4 %, n = 5), etc. The determination results are given for a group of real life samples.

J. Chinese Trad. Patent Med. (Zhongchengyao) 27 (4), 407-410 (2005). TLC of the extracts on silica gel with 1) benzene - ethanol 2:1 and 4:1; 2) n-butanol - glacial acetic acid - water 7:1:2; 3) chloroform - methanol 9:1. Detection under UV 365 and 254 nm. Identification by fingerprint technique. Quantification of 2, 3, 5, 4’-tetrahydroxystilbene-2-O-beta-D-glucoside by HPLC. The analysis results for a group of real life samples are given.

Acta Chrom. 16, 173-180 (2006). TLC of 14 performance-enhancing drugs (amphetamine, bemegride, caffeine, chlorphentermine, ephedrine, ethylamphetamine, isoproterenol, methadone, methyllendioxyamphetamine, pentazocine, pethidine, pemoline, strychnine and salbutamol) on bismuth silicate gel (prepared from 75 mL bismuth nitrate gel with 14 g silica gel powder) with thickness of 300 µm. 21 organic, aqueous and organic-aqueous mobile phases were investigated. Detection with iodine vapours.

J. Chinese Trad. Patent Med. (Zhongchengyao) 29 (3), suppl. 3-4 (2007). TLC of Liandan Xiaoyanpian tablet extracts on silica gel with 1) toluene - chloroform - acetone 4:4:1; and 2) chloroform - methanol - ammonia 36:4:1. Detection 1) by spraying with 10 % H2SO4 in ethanol and heating at 105 °C.

J. Ethnopharmacol. 158, 454-457 (2014). The authors described how the European Pharmacopoeia provides a legal and scientific reference for the quality control of medicines. The document highlighted HPTLC as a tool for the screening of herbal drugs containing certain contaminants, such as aristolochic acids._x000D_
