approach using HPTLC-densitometry

HPTLC of quercitrin (1), isoquercitrin (2), quercitrin-3-O-β-D-xylopyranosyl-α-L-rhamnopyranoside (3) on silica gel with ethyl acetate – formic acid – acetic acid – water 100:11:11:26. Detection by spraying with NEU`s reagent (diphenylborinic acid 2-aminoethylester, natural product reagent), followed by drying at 110 °C for 2 min. Quantitative determination by absorbance measurement at 265 nm. LOD and LOQ were 31 ng/zone and 75 ng/zone for (2). Recovery was between 99.8 and 101.1 % for (2). Intermediate precision was <2 % (n=3).
J. Ethnopharmacol. 197, 157-164 (2017). HPTLC of picroside I (1) and picroside II (2) in Picrorhiza kurroa on silica gel with ethyl acetate – methanol – acetic acid 46:1:1. Quantitative determination by absorbance measurement at 270 nm. The hRF values for (1) and (2) were 52 and 68, respectively.
J. Chromatogr. A 1529, 93-106 (2017). Presentation of the quantitative effect-directed profiles of 77 industrially and freshly extracted botanicals like herbs, spices, vegetables and fruits, widely used as food ingredients, dietary supplements or traditional medicine for their quality assessment with regard to potential health-promoting activities. Fast assignment of single active compounds and evaluation of their contribution to the overall activity, originating from a food or botanical sample by combination of HPTLC hyphenated with UV/Vis/FLD detection and effect-directed analysis, using the 2,2-diphenyl-1-picrylhydrazyl radical, Gram-negative Aliivibrio fischeri, Gram-positive Bacillus subtilis, acetylcholinesterase and tyrosinase assays. Characterization of bioactive compounds of interest eluted using an elution head-based interface by HPTLC-UV/Vis/FLD-EDA-ESI-(HR)MS method. Demonstration of the excellent quantification power of the method by applying for rosmarinic acid, contents ranged from 4.5 mg/g (rooibos) to 32.6 mg/g (rosemary), for kaempferol-3-glucoside from 0.6 mg/g (caraway) to 4.4 mg/g (wine leaves), and for quercetin-3-glucoside from 1.1 mg/g (hawthorn leaves) to 17.7 mg/g (thyme). The mean repeatabilities (%RSD, n=18) were ≤ 2.2 % for the three compounds and the mean intermediate precision (%RSD, n=3) was 5.2 % over three different days.
compound from Prangos platychlaena ssp
platychlaena fruit essential oils. J. Planar Chromatogr. 31, 61-71 (2018). Overpressured layer chromatography (OPLC) of two Prangos platychlaena ssp. platychlaena fruit essential oils on silica gel with toluene – isooctane 4:1, external pressure 50 bar, flow rate 100 mL/min. Bioautography by spraying with a spore suspension (105 spores/mL) of Colletotrichum species without chemical derivatization, followed by incubation for 4 days at 26 °C with a 12 h photoperiod. Detection by spraying with vanillin–sulfuric acid reagent (0.1 g vanillin in 100 mL ethanol and 2 mL sulfuric acid), followed by heating at 110 °C for 3 min.
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.
Planta Med. 83(09), 797-804 (2017). For the analysis of their sugar moieties, five new triterpene saponins (ilexpusons B, D, E, F, G), isolated from a methanolic extract of Ilex pubescens roots, were hydrolyzed at 90 °C in water containing HCl and dioxane. TLC of the dried aqueous phases on silica gel with chloroform – methanol – water 8:5:1. Detection by spraying with aniline – diphenylamine reagent (2 mL aniline, 2 g diphenylamine, 10 mL phosphoric acid 85%, in 100 mL acetone) and heating for 2-5 min at 85 °C. By comparison with standards, the sugar moiety was identified (before confirmation by GC) as glucose (hRF 49) in ilexpuson B, as xylose (hRF 81) in ilexpusons D and E, and as glucuronic acid (hRF 44) in ilexpusons F and G.
