Planta Medica 82 (16), 1438-1445 (2016). TLC on silica gel with chloroform – methanol 19:1, followed by detection under UV 254 nm and spraying with 10 % sulfuric acid with heating. TLC was used for 1) the ethyl acetate fraction of a hydromethanolic extract of Eryngium triquetrum aerial parts, and 2) for the monitoring of its fractionation on a cyclodextrin column, and of the fractionation of a selected fraction on silica gel column. The (chloroformic) first subfraction of the last step was found to contain only the polyyne alcohol falcarinol (panaxynol, carotatoxin) at hRF 90.

J. Chromatogr. 408, 449-452 (1987). Two-dimensional TLC on polyamide with 1) 5% acetic acid in water and 2) benzene - heptane - acetic acid 7:2:1. Detection by UV.

Planta Medica 83(03/04), 351-357 (2017). Acid hydrolysis of five new dammarane-type saponosides extracted from Panax japonicus var. major rhizomes for 5 h in methanol – HCl 1:1 in sealed capillary at 80°C, then TLC on silica gel with n-butanol – acetic acid – water 5:1:4 (upper phase) and with chloroform – methanol – water 16:8:1. After derivatization with aniline phthalic acid reagent, sugar moieties were identified as glucose units by comparison to standards. Note that in the title, by ignorance of the Latin grammar, the authors wrote “Panacis majoris” instead of the nominative “Panax major”. In the names of the compounds, the –ane or –ene ending was often also omitted.

Borgazdaság 36, 21-24 (1988). TLC of sorbitol in table wine on silica with isopropanol - 0.1N boric acid 85:15. Detection by spraying with 0.1M sodium metaperiodate reagent and benzidine - ethanol - acetone - water - hydrochloric acid reagent. Detection limit, 100 mg/L sorbitol.

Ind. J. Pharm. Sci. 70 (3), 395 - 398 (2008). TLC of propranolol hydrochloride on silica gel with isopropanol - ethyl acetate - ammonia 2:17:1. Quantitative determination by absorbance measurement at 290 nm. The linearity of the method was between 200 and 2000 ng/spot. The method was successively applied for tablets, wherein, no interference from tablet excipients was observed.

Planta Medica 83(03/04), 239-244 (2017). HPTLC of flavokawin B (purity checked by TLC, followed by sulfuric acid detection) and a hexane maceration of Polygonum ferrugineum aerial parts on silica gel, twice in the same direction with n-hexane – ethyl acetate 4:1 (humidity 33 %). Detection of flavokawin B by densitometry at 366 nm (without derivatization). The hRf value was 53. The content of flavokawin B was 13.6 % in the hexane extract and 1.0 % in the dried plant.

Acta Chimica 127, 95-58 (1990). TLC of hydroxy-propylated dodecyl alcohol and dodecyl alcohol on silica with acetone - methanol - water 50:50:1.

J. Planar Chromatogr. 23, 198-200 (2010). Proposition of new methods for calculation of the partition coefficients of aliphatic compounds from experimental Rf values and the numerical values of selected topological indexes. The experimental partition coefficient (log Pexp) of cetyl alcohol was determined for the n-octanol-water system. Numerical values obtained were compared with theoretical values from a database (AlogPs, AC_logP, AB/LogP, ALOGP, milogP, and XLOGP2). HPTLC of cetyl alcohol, stearyl alcohol, palmitic acid, stearic acid, alpha-hydroxypalmitic acid, and 12-hydroxystearic acid on RP18 with methanol and with methanol - water 19:1 in a horizontal chamber at room temperature. Detection after visualization in iodine vapor.
