J. Planar Chromatogr. 17, 14-17 (2004). HPTLC of oxindole alkaloids on silica gel, Diol-, CN-, NH2-, and RP-18-phases. Normal-phase TLC with 1) ethyl acetate - methanol - water 200:27:20; 2) ethyl acetate - methanol - water - acetic acid 100:2.7:5:3; 3) ethyl acetate - methanol - water - formic acid 100:2.7:5:3; 4) ethyl acetate - isopropanol - ammonia 100:2:1. RP TLC with water - methanol 7:3 containing 0.25 % ammonia; development in horizontal chamber (sandwich configuration) at room temperature. Two-dimensional TLC with mobile phase 2 in the first direction and, after drying, with mobile phase 3 in the second direction. Evaluation under UV 254 nm and after derivatization with iodine reagent or with Dragendorff reagent. TLC separations were documented by scanning. Silica and cyanopropyl layers with acidic aqueous mobile phases gave the best separation.

J. Planar Chromatogr. 17, 147-148 (2004). TLC of capsaicin on silica gel with concentration zone with toluene - acetone - chloroform 8:7:5 and 9:6:5. Detection by spraying with a 0.25 % ethanolic solution of 2,6-dichloroquinone-4-chlorimide or by exposure to iodine vapor.
Chinese J. Trad. Patent Med. (Zhongchengyao) 26 (6), 449-452 (2004). TLC of Qixuekang oral liquid extract on silica gel with 1) chloroform - ethyl acetate - methanol - water 15:40:22:10; 2) chloroform - methanol - water 28:10:1. Detection 1) by spraying with 10 % H2SO4 in ethanol and heating; 2) under UV 365 nm. Identification by fingerprint techniques. Quantification of notoginsenoside R1 by HPLC with method validation.
J. Planar Chromatogr. 17, 372-374 (2004). TLC of aflatoxins B1, B2, G1, and G2 on silica gel with chloroform - acetone 23:2 in unsaturated chambers. Detection under UV light at 366 nm. Selection of the optimum mobile phase composition by software programs.
seed and the phoney, Xanthium Spinosam L. seed) (Chinese). Chinese J. Hosp. Pharm. (Zhongguo Yiyuan yaoxue Zazhi) 25 (2), 185-187 (2005). HPTLC on silica gel with n-butanol - glacial acetic acid - water 4:1:5. Detection by exposing to ammonia vapours. Identification by fingerprint technique combined with morphological differentiation and UV spectra comparison.
J. Planar Chromatogr. 17, 250-254 (2004). TLC of three series of beta - diketonato complexes of the type [M(acac)3-n(phacphac)n], [M(acac)3-n(phacphSac)n], and [M(acac)3-n(phSacphSac)n] (where M represents cobalt(III), chromium(III), or ruthenium(III), acac is the 2,4-pentanedionato ion, phacphac is the 1,3-diphenyl-1,3-propanedionato ion, phacphSac is 3-mercapto-1,3-diphenyl-prop-2-en-1-one, phSacphSac is the 3-mercapto-1,3-diphenyl-prop-2-en-1-thion ion, and n = 0-3) on silica gel with five mono-component (chloroform, toluene, dichloromethane, xylene, tetrahydronaphthalene) and five two-component eluents (n-amyl acetate - carbon tetrachloride 1:1, n-butyl acetate - carbon tetrachloride 2:3, chloroform - carbon tetrachloride 1:1 and 3:7, and dichloromethane - carbon tetrachloride 4:1. Separations were performed in a horizontal chamber after equilibration for 30 min. After development the colored spots were readily visible.
J. Planar Chromatogr. 18, 251-252 (2005). TLC of 22 silylated amino acids on silica gel with butanol. After spotting the plates with the amino acid solutions the samples were sprayed with hexamethyldisilazane reagent (1 % solution in acetone), dried, heated at 110 °C for 20 min, and cooled. The developed plates were dried, sprayed with ninhydrin (0.25 % solution in acetone), dried completely, then further heated at 110 °C for 20 min. Detection limits of this method within 10 min are comparable with those of other methods.
