Chromatographia 47, 215-218 (1998). HPTLC on silica gel with toluene - ethyl acetate - formic acid 6:2:1. Quantitation by fluorodensitometry at 313 nm. Validation of the method by spiking uncontaminated extracts of maize with zearalenone over the range 10 to 320 mg/kg, with a linearity range between 10 and 80 mg/kg. Detection limit 2.6 mg/kg. Recovery > 62.8% (n=5).

J. Chinese Trad. Patent Med. (Zhongchengyao) 20 (4), 12-14 (1998). TLC on silica gel with 1) petroleum ether - methyl acetate - formic acid 10:5:1, 2) chloroform - methanol - NH3 30:4:1, 3) chloroform - ethyl acetate - methanol - water 15:40:22:10, 4) petroleum ether - ethyl acetate - formic acid 10:5:1. Detection 1) under UV 365 nm, 2) spraying with KJ solution in ethanol, 3) spraying with 10% sulfuric acid in ethanol. Quantitation of emodin by densitometry at 440 nm. Precision = 3.4% (n=5) plate-to-plate and 2.7% (n=5) within plate. Recovery 98.1 ± 1.27% (n=4).
Acta Chromatographica 14, 60-69 (2004). TLC on silica gel with 1-butanol - glacial acetic acid - water 3:1:1 with chamber saturation. Detection by spraying with ninhydrin reagent (0.3 g ninhydrin in 100 mL 1-butanol plus 2 mL glacial acetic acid), followed by heating at 110 ºC for several min. Quantification by densitometry at 495 nm. Validation of the accuracy by analysis of spiked blank and standard addition samples and precision by performing replicate analysis on a single day and on different days. Recoveries and RSD for spiked blank and standard addition samples were 98.8 % and 98.5 %, 1.92 % and 0.67 %, respectively. Discussion of use of the method for the routine quality control of nutritional supplements.
J. Chinese Trad. Patent Med. (Zhongchengyao) 25 (12), 964-967 (2004). TLC on silica gel with 1) chloroform - methanol - acetone - formic acid - water 54:14:8:6:1, 2) toluene (saturated with water) - ethyl acetate - formic acid 5:4:1, 3) cyclo hexane - ethyl acetate 5:1. Detection 1) by iodine vapor, 2) under UV 365 nm. Identification by fingerprint techniques. Quantitative determination of acetaminophen and chlorogenic acid by HPLC.
CBS 86, 7 (2001). HPTLC on silica gel in horizontal development chamber with acetone - water 9:1 with chamber saturation for 15 min. Detection by dipping 1 s in 0.02 % 4-nitrosodimethylaniline in ethanol with 0.01 N HCl (adjusted at pH 2) followed by heating at 150 °C. Quantitative determination by absorbance measurement at 495 nm.
J. Chinese Trad. Patent Med. (Zhongchengyao) 25 (12), 970-974 (2004). TLC on silica gel with 1) ethyl acetate - methanol - water 6:1:3, 2) n-butanol - glacial acetic acid - water 4:1:5, 3) chloroform - methanol - water 28:10:1. Detection 1) by spraying with 1 % AICl3 and under UV 365 nm, 2) by spraying with 0.5 % ninhydrin in ethanol and heating at 105 ºC, 3) under UV 365 nm. Identification by fingerprint techniques. Quantitative determination of puerarin by HPLC.
J. AOAC Int. 87, 523-539 (2004). TLC of e. g. trans- and cis-18:1 isomers of fatty acids on silica gel impregnated with silver nitrate (10 % solution of silver nitrate in acetonitrile) with toluene, benzene or mixtures of toluene - hexane 1:1, hexane - diethyl ether 9:1, and hexane - chloroform. The plates are normally developed at room temperature in a dark place. The resolution of some positional 18:1 and 18:2 isomers may be improved by development at about -20° or -25 °C. Detection by spraying with 0.05 % rhodamine B in ethanol. GC after extraction.
