J. Agric. Food Chem. 49, 832-839 (2001). TLC of lutein, anteraxanthin, violaxanthin, neoxanthin on silica gel with petroleum ether (65-95°C) - acetone - dimethylamine 10:4:1.
J. Planar Chromatogr. 17, 95-101 (2004). TLC of 15 flavonoids (flavanone, naringenin, flavone, 3-, 6-, 6’-, 7-hydroxyflavone, 3,6-, 3,7-dihydroxyflavone, morin, chrysin, quercetin, galangin, apigenin, kaempferol) and 4 phenolic acids (o-, p-coumaric acid, caffeic acid, ferulic acid) on silica gel after prewashing with methanol with 11 mobile phases. Chloroform - methanol - 98-100 % formic acid 441:30:235 and n-hexane - ethyl acetate - glacial acetic acid 31:14:5 were the most appropriate eluents. Detection under UV light at 254 and 366 nm or after spraying with 1 % methanolic diphenylboryloxyethylamine and 5 % ethanolic poly(ethylene glycol) 4000, and under UV light at 366 nm after spraying with 1 % ethanolic aluminum chloride solution.
J. Planar Chromatogr. 19, 191-194 (2006). TLC of the flavonoid and triterpenoid soyasaponin content (rutin, vitexine, isovitexine, soyasaponin I and VI as standards) on silica gel in a twin-trough chamber with ethyl acetate - formic acid - acetic acid - water 100:11:11:26 for flavonoids. Detection with diphenylboric acid 2-aminoethylester (natural products reagent) followed by PEG reagent. For soyasaponins chloroform - methanol - water 6:4:1 was used. Detection by spraying with anisaldehyde - sulfuric acid reagent followed by heating at 115 °C.
Int. J. Chem Sci 7(2), 986-992 (2009). A validated HPTLC method is reported for estimation of rofecoxib and tizanidine hydrochloride in combined dosage form. HPTLC on silica gel with methanol - ethyl acetate 1:1. The hRf value of tizanidine was 45 and of rofecoxib 67. Densitometric evaluation at 254 nm. The method was linear in the range of 180-260 ng/band for tizanidine and 2000-3000 ng/band for rofecoxib. Recovery was in the range of 99.5 - 102.5 % for both compounds. The method was suitable for routine quality control of combine dosage form.
J. Planar Chromatogr. 28, 61-66 (2015). HPTLC of swertiamarin in extracts of Enicostemma littorale and Swertia chirata on silica gel with ethyl acetate – methanol – water 16:3:1. Quantitative determination by absorbance measurement at 246 nm. The hRF value of swertiamarin was 58. Linearity was between 200 and 1200 ng/zone. The intermediate intra-day and inter-day precisions were below 2 % (n=6). The LOD and LOQ were 38 and 115 ng/zone, respectively. Recoveries were in the range of 98-100 %.
J. Planar Chromatogr. 29, 330-335 (2016). HPTLC of wedelactone in Eclipta alba, Wedelia calendulacea and Wedelia trilobata on silica gel with toluene – chloroform – ethanol – formic acid 10:8:2:1. Quantitative determination by absorbance measurement at 351 nm. The hRF value for wedelactone was 29. Linearity was between 80 and 280 ng/zone. The intermediate precision was below 2.5 % (n=3). The LOD and LOQ was 0.36 and 1.09 ng/zone, respectively. Recoveries were between 99.4 and 100.3 %.
Planta Med. 83(09), 812-818 (2017). Some of the column subfractions obtained (with different mixtures of hexane – acetone – isopropanol) from an ethyl acetate extract of Cratoxylum cochinchinense twigs and boughs were submitted to a preparative TLC on silica gel for the isolation of the following xanthones and anthracenones: (1) β-mangostin, cochinchinone and cratoxanthone D with chloroform – acetone 10:1, (2) allanxanthone by three-stage elution with benzene – acetone 10:1, n-hexane – ethyl acetate 3:1, and n-hexane – acetone 3:1, (3) cratoxanthone A by similar three-stage elution (third step: chloroform – acetone 10:1), (4) visminone F by two-step elution with benzene – acetone 10:1, and isopropanol – acetone 5:1, (5) cratoxanthone B and garcinone E by a two-step elution with isopropanol – acetone 4:1, and n-hexane – acetone 3:1, (6) α-mangostin and mangostenol by a two-step elution with chloroform – acetone 20:1, and n-hexane – isopropanol – acetone 5:5:1, (7) cratoxanthone C by a two-step elution with benzene – ethyl acetate 5:1, and chloroform – acetone 20:1.
