J. Chinese Pharm. Univ. (Zhongguo Yaoke Daxue Xuebao) 26, 353-355 (1995). TLC of saikisaoponin on silica with chloroform - pentane - methanol - butanol - acetic acid - water 60:36:22:9:4:2. Detection under UV 254 nm. Quantification by spectrophotometry at 545 nm after elution.

J. Planar Chromatogr. 10, 217-219 (1997). TLC of phenolphthalein glucuronide and salicylic acid on RP-18 silica with methanol - water 3:1. Visualization under UV 254 nm. The spectra shown in the publication represent the first demonstration that HR MAS (high resolution magic-angle-spinning) can provide NMR data for compounds such as these directly, without the need for their elution from the stationary phase.

J. Chinese Trad. Patent Med. (Zhongchengyao) 20 (2), 23-25 (1998). TLC on silica gel with chloroform - ethyl acetate - methanol 50:1:1. Detection by spraying with 0.5% phosphomolybdic acid in ethanol and heating at 110°C for 8-10 min. Quantitation of b-cholesterol by densitometry at 600 nm, and of total flavonoids by UV spectrophotometry. Precision for b-cholesterol = 2.94% (n=4). Recovery 98.64 ± 2.28% (n=4).

USA 94, 6036-6041 (1997). TLC of N-acylated derivatives of L-homoserine lactone (acyl-HSLs) on RP-18 with methanol - water 3:2. The spots were visualized by overlay of a bacterial reporter strain. Spots of preparative TLC were scraped off and submitted to Electrospray ionization mass spectrometry (ESIMS).

Detection by exposure to iodine vapor. Comparison of the finger prints of the hydrolysis solution obtained at different conditions.

J. Planar Chromatogr. 17, 244-249 (2004). TLC of thirty compounds (coumarin derivatives) including by-products on silica gel with ethyl acetate - hexane 2:3 or, for more polar synthesized compounds, with methanol - dichloromethane 7:93 in a saturated chamber. Detection under UV light at 254 nm, and by derivatization if necessary, e. g. by iodine reagent. Quantitative determination by densitometry at 292 - 363 nm. Direct screening of the reaction mixture on the plate for antioxidant activity against the 1,1-diphenyl-2-picrylhydrazyl (DPPH) test radical.

J. Chromatogr. A 1217(1), 99-103 (2010). Discussion of the definition of multidimensional (MD) separations, especially some potentially powerful separation techniques such as comprehensive 2D LC (LC × LC), and comprehensive 2D GC (GC × GC). The definitions of MD separations have been extended by some researches beyond their intended scope. This disqualifies comprehensive 2D techniques as LC × LC, GC × GC and 2D TLC from being considered as 2D techniques. In other instances, extended treatment of the definition is used as a basis to justify design-parameters of comprehensive 2D separations despite the fact that these parameters lead to sub-optimal implementations. The review draws attention to the shortcomings in the definition, discusses the weaknesses in the currently used definitions, and proposes to define n-dimensional analysis as one that generates n-dimensional displacement information.
