J. Chin. Trad. Med. (Zhongguo Zhongyao Zazhi) 20, 197-199 (1995). TLC on silica with the lower phase of chloroform - methanol- water 13:7:2. Detection by spraying with 2.5 % phosphomolybdic acid in ethanol. Quantification of total saponins by colorimetry, and of ginsenoside Rb1 and Rg1 by densitometry at 610 nm.

(Coupling AMD-SERS/RAMAN). InCom-Sonderband 47-55 (1997). Investigation of the evaporation of silver on silica gel plates in a newly developed evaporation chamber. The intention is to improve the sensitivity of Raman spectroscopy to such an extent that the amounts of substance detectable in TLC (in the nanogram range) can be measured. The SERS (Surface Enhanced Raman Spectroscopy) effect was used.

Chinese J. Pharm. Ind. (Zhongguo Yiyao Gongye Zazhi) 29, 43 (1998). TLC on silica gel with acetone - ethyl acetate - water - diethylamine 10:10:2:1. Detection by exposure to iodine vapor. Identification by comparison to standards and verification by IR.

Anal. Biochem. 270, 314-422 (1999). HPTLC of the dihexadecyl phosphatidylethanolamine (DHPE) derivatives of the periodate oxidation products of disaccharides, and of oligosaccharide alditols, respectively, on silica gel with chloroform ñ methanol - water 130:50:9. Visualization after spraying with primuline reagent under long-wave UV. Quantitative estimates by fluorometric scanning densitometry. In situ analysis of the derivatives by liquid secondary ion mass spectrometry (LSIMS).

J. Chinese Trad. & Herb. Drugs (Zhongcaoyao) 32 (2), 122-124 (2001). TLC on silica gel with 1) chloroform - methanol 17:3, 2) ethyl acetate - methanol 9:1. Detection by spraying with 10% sulfuric acid in ethanol and heating at 105°Cfor 5 min. Identification by finger print technique. Quantitation of polysaccharides by UV spectroscopy.

J. Planar Chromatogr. 17, 420-423 (2004). A new on-line TLC-MS interface, with computer-controlled extraction of substances from selected spots on a TLC or HPTLC plate, has been constructed. The controlled collection of the sample and its programmed injection into the mass spectrometer is the advantage of this type of interface. It has been tested and validated with a standard solution of caffeine as test substance. HPTLC of caffeine on silica gel with dichloromethane - methanol 9:1. Quantification with a video-documentation system.

J. Chromatogr. A 1155 (1), 112 - 123 (2007). Presentation of a novel strategy for the fractionation of complex peptide mixtures using two-dimensional planar electrochromatography/thin-layer chromatography. Migration of phosphopeptides is slower in the first dimension, based upon their anionic phosphate residues, and certain predominantly acidic phosphopeptides even migrate in the opposite direction, relative to the bulk of the peptides. Further distinguishability of phosphopeptides are based upon hydrophilicity in the second dimension, which permits a restricted region of the plate to be directly examined for the presence of phosphopeptides by mass spectrometry. Phosphopeptide analysis from the plates by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF)-MS and tandem MS enabled peptide sequencing and identification.

J. Planar Chromatogr. 21, 15-20 (2008). TLC and OPLC of polyacetylenes of chamomile, trans-resveratrol, salicylic acid, and ochratoxin A on silica gel (preconditioned at 120 °C for 3 h) with chloroform - methanol 20:1. Detection by bioautography with Pseudomonas savastanoi pv. phaseolicola race 6 and by immersing the humid plate into MTT solution for 5 s.
