J. Planar Chromatogr. 18, 377-379 (2005). HPTLC of 2-azaanthraquinone from plant extracts on silica gel with toluene - ethyl acetate - methanol 40:9:1. Quantitative determination by absorbance measurement at 310 nm. Calibration was linear in the range of 10-100 µg/mL. The method was repeatable and precise with RSD between 0.98 and 1.59 % intra-day and between 3.41 and 5.56 % inter-day. Limits of detection and quantification were 3 and 6 µg/mL.
Planta Med. 70, 834-840 (2004). Analytical and preparative TLC of flavonoids (lavandulifolioside, plantamajoside, acteoside, leucosceptoside, and martynoside) on silica gel, RP18, polyamide and cellulose. E. g. 2D-TLC on cellulose with n-butanol - acetic acid - water 4:1:5 in the first and acetic acid - water 15:85 in the second direction, preparatice TLC on polyamide with ethyl acetate - ethanol - water 20:3:2 (2 x), 50:3:10, and 25:3:3 (4 x). Detection under UV light at 366 nm before and after spraying with 0.1 % diphenylboric acid 2-aminoethylester (natural products reagent) or 1 % aluminium chloride solution in ethanol.
Planta Med. 71, 764-769 (2005). Preparative TLC of 9 known diterpenoids and shikokianin and rabdoternin A on silica gel by two-fold development with chloroform - methanol 30:1, and of rabdosichuanin and lasiokaurin with chloroform - acetone 6:1. Detection under UV light at 254 nm.
Planta Med. 70, 509-514 (2004). Analytical and preparative TLC of a new iridolactone (4R,5R,7S,8S,9S)-7-hydroxy-8-hxdroxymethyl-4-methyl perhydrocyclopenta[c]pyran-1-one) on silica gel and RP18 with acetonitrile - water 1:1. Detection by dipping in phosphomolybdic acid or vanillin - sulfuric acid reagent followed by heating at 110 °C for 5 min.
Planta Med. 72, 175-179 (2006). Preparative TLC of 1beta,6beta-diangeloyloxy-8beta,10beta-dihydroxyeremophil-(11)-en-8alpha,12-olide, 1beta,6betadiangeloyloxy-8alpha,10alpha-dihydoxyeremophil-7(11)-en-8beta,12olide, 1beta-angeloyloxy-8-oxoeremophil-6,9-diene-12-oic acid methylester on silica gel with petroleum ether (60-90°) - acetone 3:1. Detection under UV light at 254 nm or by spraying with 98 % sulfuric acid - ethanol 1:19 followed by heating.
Planta Med. 71, 680-682 (2005). Analytical and preparative TLC of 5-hydroxy-2-methoxyxanthone, 2-hydroxy-3-methoxyxanthone, trans-kielcarin, 4-hydroxy-3-methoxyphenyl ferulate, and 3beta-O-caffeoylbetulinic acid on silica gel with chloroform - petroleum ether - formic acid 950:50:1, chloroform - acetone - formic acid 950:50:1, 900:100:1, and 850:150:1. Detection under UV light at 254 nm.
J. Planar Chromatogr. 19, 398-400 (2006). HPTLC of curcumin, piperine, and thymol on silica gel, pre-washed with methanol, without chamber saturation with toluene - ethyl acetate - methanol 18:2:1. Quantitative determination by absorbance measurement at 420 nm for curcumin, 333 nm for piperine, and 277 nm for thymol. Limit of detection for curcumin was 25 ng, for piperine 5 ng, and for thymol 50 ng. Rapid identification of the three compounds is also possible by spraying the plate with anisaldehyde in sulfuric acid reagent.
Indian Drug 44 (2), 122-127 (2007). HPTLC of ayurvedic medicated oil on silica gel in a twin-trough chamber with ethyl acetate - toulene 1:9 for fingerprint analysis, and ethyl acetate - methanol - water 200:27:20 for quantitative determination of colchicine.
