J. Planar Chromatogr. 19, 273-277 (2006). TLC of the 2-arylpropionic acids S-(+)-ibuprofen, S,R-(+/-)-ibuprofen, S-(+)-naproxen, and S,R-(+/-)-2-phenylpropionic acid on silica gel pre-developed with methanol - water 9:1 and impregnated with L-arginine in the cationic form as chiral ion-pairing reagent. Acetonitrile - methanol - water 5:1:1 (with several drops of glacial acetic acid to fix the pH at < 4.8) was used for ibuprofen, 10:2:3 for naproxen and 20:4:3 for 2-phenylpropionic acid. Quantitative determination by absorbance measurement at 210 nm.

J. Liq. Chromatogr. Relat. Technol. 28, 297-311 (2005). TLC of cholic acid, glycocholic acid, glycodeoxycholic acid, chenodeoxycholic acid, deoxycholic acid, lithocholic acid, and glycolithocholic acid on RP-18 W with methanol - water, (acetonitrile - methanol 1:1) - water, acetone - water, dioxane - water in different volume compositions. Detection by spraying with 10 % aqueous solution of sulfuric acid or by dipping in 10 % ethanolic solution of phosphomolybdic acid followed by heating at 120 °C for 20 min.

J. Liq. Chromatogr. Relat. Technol. 28, 2261-2271 (2005). HPTLC of 21 butylthiocarbamyl-amino acids on silica gel in a saturated horizontal chamber. Pre-chromatographic derivatization with 2-propanol - BITC - triethylamine was carried out after application of the amino acids. For the reaction the plate was placed in a glass chamber in a thermostat at 40 °C for 30 min. Then the plate was developed with ethanol - methanol - chloroform 1:1:2. Detection by spraying with a freshly prepared mixture of 3 % sodium azide and 0.5 % starch solution adjusted to pH 5.5 and exposed to iodine vapor for 5 s. Quantities in the range of 2-90 pmol per spot were detected.

Pharmazie 61,728-731 (2006). TLC of myrracadinol A, myrracalamene A, myrracalamene B, myrracadinol B. triacont-1-ene, myrracalamene C, and myrracadinol C on silica gel with petroleum ether, toluene, petroleum ether - chloroform 4:1, toluene - chloroform 4:1, benzene, benzene - ethyl acetate - diethyl amine 6:3:1, or chloroform- methanol 17:3. Detection under UV light, by exposure to iodine vapors and by spraying with ceric ammonium sulfate.

Pharmazie 62, 231-234 (2007). TLC of flavan-3-ols and dimeric and trimeric procyanidins on silica gel with ethyl acetate - formic acid - water 18:1:1. Detection by spraying with natural products reagent, vanillin-hydrochloric acid, and anisaldehyde-sulfuric acid.

J. Liq. Chromatogr. & Relat. Technol. 29, 2603-2609 (2006). TLC of phenolic and terpenoid compounds with 4’-O-beta-D-glucopyranosyl-3’,5’-dimethoxy-benzyl-caffeate as standard on silica gel with chloroform - ethanol - acetic acid 30:20:3. Detection by spraying with anisaldehyde - sulfuric acid reagent and heating to 100 °C, and 1% methanolic diphenylboryloxyethylamine, followed by PEG 400. Evaluation under visible and UV light at 366 nm.

J. Planar Chromatogr. 20, 127-130 (2007). TLC of isorhamnetin-3-glucoside, isorhamnetin-3-rutinoside, kaempferol-3-rhamnosidoglucoside, isoquercitrin, rutoside, hyperoside on silica gel in horizontal chamber with ethyl acetate - methyl ethyl ketone - formic acid - water 5:3:1:1 or ethyl acetate - formic acid - water 9:1:1. Quantitation by scanning at 366 nm; detection by spraying with a 1 % methanolic solution of Natural Product Reagent A followed by a 4 % methanolic solution of polyethylene glycol 400.

3. Test fungus: Candida albicans. J. Planar Chromatogr. 20, 385-389 (2007). Optimum conditions have been established for culture of the fungus Candida albicans for microbial detection of zones in direct bioautographic TLC. On the basis of the results with Candida albicans it can be differentiated between microbiostatic (bacteriostatic or fungistatic) and microbiocidal (bactericidal or fungicidal) effects on TLC plates. Aqueous solutions of amphotericin B and fluconazole were spotted on TLC plates coated with silica gel. After drying the plates were immersed in microbial suspensions with different optical densities. The viability and metabolic activity were evaluated by use of a bioluminescence ATP assay modified by Köszegi.
