Lipids 18, 87-89 (1983). The chromatographic mobilities of 17 sterols and squalene on reversed-phase TLC plates with 4 nonaqueous solvent systems is described. Solvent Systems: hexane - ethyl acetate 9:1 and other systems were used. Visualization: 10 % phosphomolybdic acid in 95 % ethanol, followed by heating at 100 °C; iodine vapor; 10 % sulfuric acid in 50 % methanol, followed by heating at 100 °C.
(Hungarian) (Data on the thermo and light stability of the receptorblocking agent CH-103.) CH-103 = (4-cyclohexylamino-1-(1-naphtyloxy)-2-butanol-hydrogenmaleate) is a new Hungarian pharmacon. TLC on silica with ethyl acetate - methanol -25 % NH3 8:1:1 Detection by UV and with iodine. Spectrophotometry after elution. Main decomposition products identified: 1-naphtol, 4-cyclohexylamine-1,2-butandiol, 1-cyclohexenyl-3-pyrrolidinol.
J. Chromatogr. 329, 107-112 (1985). TLC of seventeen synthetic drugs reported as adulterants of Chinese herbal preparations on silica with dichloromethane - methanol - water 183:27:5, ethyl acetate - toluene - formic acid - DMF - water 75:75:2:4:4, dichloromethane - methanol 183:27 or ethyl acetate - toluene - formic acid - DMF 75:75:2:4. Detection by UV 254 and 366 nm. Rf values for all the drugs in numerous solvent systems are given.
Shanghai 1st. Med. Coll.(Shanghai Diyi Yixueyuan Xuebao) 11, 284-287 (1984). (Chinese). (Evaluation of total alkaloids in Chinese traditional drugs fen fang ji by TLC-spectrophotometric method.) TLC of tetradrine on silica with methanol - chloroform 1:5. Detection by UV. Quantification by spectrophotometry of methanol - eluate at 282 nm.
J. Chromatogr. 350, 151-168 (1985). TLC on silica with four developing systems: 1) ethyl acetate - methanol - 30% NH3 85:10:5, 2) cyclohexane. - toluene - diethylamine 65:25:10, 3) ethyl acetate - chloroform 5:5, 4) acetone with the plate dipped in KOH solution. Detection by spraying with Dragendorff reagent and acidified iodoplatinate solution. A two-component model accounting for 73% of the total variance. Results of great practical importance in analytical toxicology.
(Echinacea drugs- standardization using HPTLC and TLC.) Dtsch. Apoth. Ztg. 126, 1065-1070 (1986). TLC of sesquiterpene esters on silica with toluene - ethyl acetate 7:3.
