II. Quantitative TLC determination of digoxin and other glycosides on pretreated digitalis lanata extracts. Acta pharmac. Hungarica 52, 133-140 (1982). TLC of digoxin, lanatoside C on silica with dichloromethane - methanol - water 170:27:3 or 80:18:2. Detection with xanthydrol reagent (0.1 g xanthydrol in 96 ml acetic acid + 3 mL H2SO4 + 1 ml HCl). Photometry after elution at 530 nm.
Planta Med. 71, 673-679 (2005). Analytical and preparative TLC of 18-(beta-D-glucopyranosyloxy)-28-oxoolean-12-en-3beta-yl 3-O-(beta-D-glucopyranosyl)-beta-D-glucopyranosiduronic acid methyl ester, achyranthoside C dimethyl ester, achyranthoside C butyl dimethyl ester, achyranthoside E dimethyl ester, achyranthoside E butyl methyl ester (and 10 known compounds) on silica gel and RP18 with chloroform - methanol - water 8:5:2 or methanol - water 1:1, respectively. Detection under UV light at 254 nm or by spraying with cerium sulfate - 10 % sulfuric acid 1:99.
LXXXII. 5, 5-disubstituted barbituric acids and their analogues. Coll. czechoslov. chem. comm. 48, 137-143 (1983). TLC of 5, 5-disubstituted barbituric acids on silica with a) chloroform - methanol -25 % NH3 4:4:2, b) propanol -24 % NH3 7:1:2. Detection by UV.
Planta Med. 70, 1216-1221 (2004). TLC of 20-formylbenz[6,7]indolizino[1,2-b]quinolin-11(13H)one, 10-methoxy-20-O-acetylcamptothecin, 20-O-beta-glucopyranosyl-18-hydroxycamptothecin, 3,4-methylenedioxy-3’-O-methyl-5’hydroxy ellagic acid and 18 known compounds on silica gel with chloroform - methanol 4:1, chloroform - ethyl acetate 6:1, ethyl acetate - hexane 4:1, and ethyl acetate - acetone 1:4. Detection under UV light.
Synthesis of 13-oxa-prostacyclins. Acta Chimica 113, 355-365 (1983). TLC of 13-oxa-prostacyclins on silica with chloroform - acetone - ethyl acetate 7:3:0.1. Detection by UV 254 nm.
J. Liq. Chromatogr. & Relat. Technol. 29, 2141-2151 (2006). HPTLC of flavonoids (with rutin, chlorogenic acid, hyperoside, and gallic acid as reference substances) on silica gel in a twin-trough chamber with ethyl formate - toluene - formic acid - water 60:3:8:6. Detection by dipping the hot plate (heated at 100°C for 2 min) into natural products reagent, followed by drying, dipping into polyethylene glycol 400 (10 g in 200 mL dichloromethane), and drying. Evaluation under UV 366 nm. With this method the geographical origin of the material can be determined. Toluene - acetone - formic acid 9:9:2 allows the discrimination of green from black and other speciality teas, based on the polyphenol pattern. Detection by dipping the hot plate (heated at 100°C for 2 min) into a solution of Fast Blue salt B, followed by detection under white light. For investigation of the alkaloid profil ethyl acetate - methanol - water 20:2.7:2, followed by detection under UV 254 nm is used. The amino acid profile is analyzed by using 1-butanol - acetone - acetic acid - water 7:7:2:4. Detection by dipping into ninhydrin reagent, followed by heating at 110°C for 3 min and evaluation under white light. The method for polyphenols was validated regarding specificity, stability, reproducibility, and robustness.
J. Chromatogr. 274, 289-298 (1983). TLC of metamizole metabolites on silica with chloroform - methanol - ether -25 % NH3 25:5:6:1. In situ fluorometry at 265 nm.
Pharmazie 60, 953-955 (2005). TLC of cochleareine, acoleareine, 14-acetyltalatisamine, and talatisamine on silica gel. Detection under UV light at 254 nm. Also co-chromatography with standards. Using a Chromatotron apparatus the crude alkaloidal mixture was separated on alumina radial plates and eluted with a gradient of petroleum ether, chloroform, and methanol.
