For quality control, TLC of its extracts, the respective reference drug and selected standards on silica gel (1) for Rheum palmatum L., with petroleum ether (30-60 ˚C) – ethyl formate – formic acid 15:5:1, detection under UV 365 nm; (2) for Cortex phellodendri (and berberine hydrochloride), with n-butanol – glacial acidic acid – water 7:1:2, detection under UV 365 nm; (3) for Radix paeoniae rubra (and paeoniflorin), with chloroform – ethyl acetate – methanol – formic acid 40:5:10:0.2, detection by spraying with 5% vanilline in H2SO4 – ethanol 1:4 and heating at 85 ˚C until the zones are visible in daylight; (4) for Angelica dahurica (Fisch. ex Hoffm.) Benth. et Hook. f. ex Franch. et Sav (and iso-/imperatorin), with petroleum ether (30-60 ˚C) – diethyl ether 3:2, detection under UV 365 nm; (5) for Pericarpium citri reticulatae (and hesperidin), first with ethyl acetate – methanol – water 100:17:13 up to 30 mm, then with the upper phase of toluene – ethyl acetate – formic acid – water 20:10:1:1 up to 80 mm, detection by spraying with 5% AlCl3 in ethanol and viewing under UV 365 nm; (6) for Boswellia carteri, with cyclohexane – ethyl acetate 11:2, detection by spraying with 5% vanilline in H2SO4 – ethanol 1:4 and heating at 85 ˚C until the zones are visible in daylight. Quantification of aloe emodin, rhein, emodin, chrysophanol, physcion by HPLC.
Planta Med. 83(17), 1321-1328 (2017). Benzoyl-aconine esters (lipo-alkaloids) produced by transesterification of aconitine (isolated from Aconitum sp.) with long-chain fatty acids were purified by a multistep chromatographic method, including cyclodextrane gel filtration chromatography, centrifugal planar chromatography on aluminium oxide layer using cyclohexane – chloroform – methanol 70:30:1 followed by 70:30:3 and/or preparative thin-layer chromatography on aluminium oxide layer with toluene – acetone – ethanol – concentrated ammonia 70:40:10:3.
Planta Med. 83(16), 1289-1296 (2017). A cycloartene-diol, a dihydroxycicloartenone and an isopimaradiene-diol were isolated from subfractions of an ethanolic extract of Guarea macrophylla (Meliaceae) leaves through elution on preparative TLC silica gel layers with chloroform – acetone 19:1, or with n-hexane – ethyl acetate 9:1 or 1:1, respectively.
Planta Med. 83(14/15), 1233-1241 (2017). HPTLC of standards and methanolic extracts of L. cardiaca, L. japonicus and L. sibiricus (Lamiaceae) acidified with formic acid on silica gel with ethyl acetate – acetic acid – formic acid – water 100:11:11:26, in an automatic development chamber with 48 % humidity (20 min presaturation). Detection under white and UV light, before and after immersion in 1) anisaldehyde – sulphuric acid (followed by heating) for the detection of iridoids; 2) natural product reagent A for phenylpropanoids; 3) modified Dragendorff reagent (bismuth oxynitrate 0.17 %, sulfuric acid 3.5 %, glacial acetic acid 2 %, potassium iodide 4 %) for alkaloids. Ajugoside (hRF 29) and verbascoside (hRF 53) were found in L. cardiaca and L. sibiricus, but absent in L. japonicus. The opposite was true for leonurine (hRF 52), whereas stachydrine (hRF 14) was found in the three species. This method allows to distinguish L. japonicus from the other species, which have to be distinguished from each other through morphology.
Planta Medica 83(01/02), 135-142 (2017). Preparative TLC on silica gel for the purification of recrystallized farnesiferol B (hRF 50; with petroleum ether – ethyl acetate 8:1) and sinkianol B (hRF 40; with chloroform – methanol 15:1) isolated through column chromatography from petroleum ether – dichloromethane fractions of the chloroform extract of Ferula sinkiangensis gum resin.
Planta Medica 83(14/15), 1176-1183 (2017). The fractionation on cyclodextrane with methanol – water 9:1 of the acetone macerate of Crocus sativus flowers (without stigma) was analyzed by TLC on silica gel with ethyl acetate – acetic acid – formic acid – water 100:11:11:26. Detection under UV light and after derivatization with natural products reagent (1 % in methanol), followed by 5 % ethanolic PEG solution. The 182 fractions were pooled into 8 fractions, whereby fraction 2 contained pure kaempferol-3-O-sophoroside (its structure and 98 % purity were confirmed by NMR). The yield was 1.4 % of the dried flowers._x000D_
of Pharm.(Yaoxue Xuebao) 20, 59-66 (1985). (Chinese). (HPLC and TLC determination of alkaloid constituents in sophara flavescens and saphora lopecuroides.) TLC of sophocarpine, matrine, sophoridine, oxymatrine and oxysophocarpine on silica with benzene - acetone - methanol 8:3:0.5. Determination by densitometry at 510 nm. Comparison with HPLC results (good agreement).
