J. Planar Chromatogr. 19, 92-97 (2006). Two-dimensional HPTLC of naringenin, acacetin, flavone, morin, hesperetin, quercetin, narcisin, kaempferol 3,7-dirhamnoside, naringin, rutin, astragalin, quercitrin, kaempferol 3-glyco-7-rhamnoside, naringenin 7-glucoside, ferulic acid, chlorogenic acid, elagic acid, caffeic acid, p-coumaric acid, m-coumaric acid, o-coumaric acid, and gallic acid by connecting diol or silica plates to RP18 plates, with e. g. acetone - water 2:3 or 1:1 in first direction of development and propan-2-ol - ethyl acetate 1:1 or methanol - ethyl acetate 1:9 in second direction of development. Derivatization by use of diphenylboric acid 2-aminoethylester (natural products reagent), followed by PEG 400 reagent; detection under 365 nm.
J. Planar Chromatogr. 19, 216-222 (2006). TLC of ciprofloxacin monohydrate hydrochloride, enoxacin sesquihydrate, fleroxacin, norfloxacin, pefloxacin dihydrate mesylate, sparfloxacin, and ofloxacin on silica gel, cellulose and RP18 with numerous mobile phases. Best separations were achieved on silica gel with methanol - acetone - 1mol/L citric acid - triethylamine 28:2:2:5, on cellulose with dichloromethane - isopropanol - tetrahydrofuran - 25% ammonia 4:6:3:3, and on RP18 with methanol - 0.07 mol/L phosphate buffer (pH 6) - 10 mmol/L benzyldimethyltetradecylammonium chloride 6:3:1. Detection under UV light at 254 nm was more sensitive than spraying with Dragendorff reagent, Forrest’s reagent, 15 % FeCl3 in 2 % HCl, iodic reagent (5 g FeCl3 and 2 g I2 in 100 mL acetone - 20 % tartaric acid 1:1), 20 % phosphomolybdic acid in 10 % sulfuric acid, and Folin-Ciocalteu reagent.
Planta Med. 70, 1195-1200 (2004). Analytical and preparative TLC of the new xanthones linixanthone A, B, C, garcibiphenyl A and B and garcibenzopyran on silica gel with n-hexane - ethyl acetate 5:1 and 10:3, and chloroform - methanol 10:1 and 5:1. Detection under UV light at 254 nm.
Influence of sample preparation methods and conditions. J. Liq. Chrom. & Rel. Technol. 27, 2463-2470 (2004). TLC of 1-(3,4-methylenedioxyphenyl)-2-nitropropene, an intermediate product of MDMA (3,4-(methylenedioxy)methamphetamine, also known as ,ecstasy’, and impurities on silica gel in a horizontal chamber with chloroform - ethyl acetate 49:1. Detection of separated impurities under UV light at 254 and 366 nm.
J. Planar Chromatogr. 19, 73-80 (2006). TLC of six atypical antipsychotic drugs (amisulpride, clozapine, olanzapine, quetiapine, risperidone, ziprasidone) on silica gel, amino, cyano, DIOL, and polyamide phases with mixtures of n-hexane and six polar modifiers (acetone, dioxane, diethylamine, ethanol, isopropanol, and tetrahydrofuran) in a horizontal DS chamber. After development the plates were inspected under UV light at 254 nm. Quantification by densitometry.
Appl. Surf. Sci. 252, 6746-6749 (2006). To show the application of direct time-of-flight secondary ion mass spectrometry (ToF-SIMS) to analyze a reaction mixture between an alpha-bromoamide (1), and picolylamine, to form the substitution product (3) via SN2 (1 and 3 are indistinguishable by TLC on silica gel with dichloromethane – methanol – ammonia 100:15:2), a series of organic halides with widely differing structures (trifluoromethanesulfonamide, a vinyl bromide, a silyl-protected primary bromide, and iodosobenzene diacetate) were separated on TLC plates under the same conditions. The resulting spots and background were analyzed by positive and negative ion spectra. In all cases, the halide signals were notably stronger than the background signals. In addition, a series of amines (1,1-carbonyl diimidazole, norepinephrine, adenosine, and cinchonidine) was separated on TLC plates and analyzed directly by ToF-SIMS. In all but one (adenosine), even quasi-molecular ions were observed.
J. Planar Chromatogr. 19, 393-397 (2006). TLC of uroporphyrin I, uroporphyrin III, coproporphyrin I, coproporphyrin III, and protoporphyrin IX (as methyl esters) on polyamide 11, cellulose and silica gel with methanol, ethanol, propanol, butanol, acetonitrile and tetrahydrofuran in a saturated chamber. Porphyrins on cellulose were detected by placing in iodine vapor for 5 min; on silica gel and polyamide 11 the porphyrins were detected as red spots in UV light at 254 nm. Chromatographic retention data and a possible retention mechanism are discussed.
