J. Chromatogr. A 1145 (1-2), 222-228 (2007). Pre-fractionation of cis and trans-fatty acids by silver-ion TLC (Ag-TLC) and other methods (silver-ion SPE (Ag-SPE) or HPLC) allows accurate determination of the isomeric profile but is not essential to achieve quantification of total trans-18:1 isomers nor to determine the level of vaccenic (trans-11 18:1) acid in dairy fat. Comparison of different GLC methods suitable to measure the total of trans-18:1 isomers, vaccenic acid and trans-18:1 acid isomeric distribution in milk fat. Pre-separation of cis- and trans-18:1 isomers by Ag-TLC followed by GLC analysis under optimal conditions was selected as the reference method.
Strait Pharm. J. 1, 53-55 (2014). Tiaojing Huoxue Jiaonang capsule is a TCM compound used clinically for the treatment of irregular menstruation, menstrual pain and other gynecological diseases. TLC on silica gel (1) for Salvia miltiorrhiza Bunge and protocatechuic aldehyde with dichloromethane – acetone – formic acid 60:5:2, detection by spraying with 5 % ferrum trichloride in ethanol and viewing under white light; (2) for Rehmannia glutinosa (Gaert.) Libosch. ex Fisch. et Mey. with petroleum ether (60-90 ˚C) – ethyl acetate 1:1, detection under white light after spraying with 2,4-dinitrophenylhydrazine – ethanol – hydrochloric acid 1:100:10. Quantitative determination of paeoniflorin by HPLC. Applying to real life samples indicated that the method was simple, specific, accurate, reproducible, robust and able to be the better alternative for the purpose to that specified in the Chinese Pharmacopoeia 2010.
H. TRAITLER, A. STUDER, R.E. KAISER eds): Instrumental HPTLC, Institute for Chromatography, Bad Dürkheim, FRG (1987), 81-92. Discussion of the potential and limitations of column liquid chromatography, planar chromatography and capillary gas chromatography with the emphasis on separation efficiency, sample pretreatment, detection and derivatization procedures, and speed of analysis. Mention of on-line coupling of various chromatographic techniques and some future trends.
Proc. 6th Int. Symp. Instrum. Planar Chromatogr., (Interlaken 1991), Inst. Chromatogr., Bad Dürkheim, FRG, 231-234 (1991). The sample preparation system includes an OPLC chamber as an interface where samples of interest are migrated toward the column of an HPLC system. Another way of clean-up is the combination of conventional TLC with OPLC transfer. According to the chromatographic properties of unwanted sample materials, the impurities in front and/or starting zone can be eliminated while analyzable compounds from the localized area of the layer can be transferred to the HPLC system.
J. Chin. Trad. Med. (Zhongguo Zhongyao Zazhi) 21, 348-350 (1996). TLC on polyamide with acetic acid, and on silica with ethyl acetate - methanol - NH3 conc. 17:2:1. Detection 1) under UV, 2) by spraying with potassium iodobismuthate reagent and sodium nitrite. Quantification of baicalin by densitometry at 282 nm. Also HPLC method.
Sz. Nyiredy, A. Kakuk (eds.): Planar Chromatography 2000, Lillafüred, Hungary, 24-26 June 2000, Res. Inst. for Med. Plants, p. 121-132. A variety of modes of multidimensional separation in TLC are shown. Two-dimensional or multidimensional planar chromatography, two-dimensional development on bilayers, coupled layers with stationary phases of decreasing polarity and combination of multidimensional planar chromatographic methods are demonstrated. The greatest strength of multidimensional separation is that compounds are distributed widely over two-dimensional space of high zone capacity. A zone capacity of ca. 1500 could be achieved. Image analyzers might improve quantitation in future.
J. Chinese Trad. Patent Med. (Zhongchengyao) 26 (1), 29-32 (2004). TLC on silica gel with 1) chloroform - ethyl acetate - methanol - water 15:40:22:10, 2) chloroform - methanol - water 13:7:2. Detection 1) by spraying with 10 % H2SO4 in ethanol and heating at 105 ºC, 2) under UV light. Identification by fingerprint technique. Quantification of chlorogenic acid by HPLC.
