J. Planar Chromatogr. 23, 40-45 (2010). HPTLC of flavonoids (vitexin, isovitexin, orientin, isoorientin, rutin) on polyamide at 23 +/- 2°C and 40 % relative humidity with the three-component mobile phase A-B-C 33:67:8, where A is dodecyl sulfate - n-butanol - n-heptane 147:158:28, B is water, and C is formic acid. The solvent mentioned gave the best resolution of vitexin (hRf 61), isovitexin (hRf 21), orientin (hRf 28), isoorientin (hRf 34), and rutin (hRf 52). Detection by spraying with 1 % aluminium trichloride in ethanol followed by waiting for approximately 1h. Quantitative determination by fluorescence measurement at 366 nm. Precision was found to be 0.98, 0.91, 1.02, 1.04 and 0.87 % for isovitexin, rutin, orientin, isoorientin, and vitexin, respectively. Average recoveries (at three different concentrations) were between 98.9 and 100.6 % from P. pubescens, P. glauca and P. yixingensis.
J. Chromatogr. A 1289, 105-118 (2013). HPTLC of 11 anthocyanes named cyanidin (1), delphinidin (2), malvidin (3), peonidin (4), pelargonidin (5), cyanidin-3-glucoside (6), delphinidin-3-glucoside (7), malvidin-3-glucoside (8), peonidin-3-glucoside (9), pelargonidin-3-glucoside (10) and malvidin-3,5-diglucoside (11) in pomace, feed, juice and wine on silica gel with ethyl acetate - toluene - formic acid - water 50:15:4:6 for the anthocyanidins (1) to (5) and ethyl acetate - 2-butanone - formic acid - water 35:15:6:4 for the anthocyanins (6) to (11). Quantitative determination by absorbance measurement using a multi-wavelength scan at 505 nm for (10), 510 nm for (5), 520 nm for (4) and (9), 530 nm for (1), (3), (6), (8) and (11) and 555 nm for (7). Detection was compared by dipping into a DPPH radical reagent solution (0.5 mM methanolic solution of the DPPH) and into Aliivibrio fischeri bioassay suspension. Linearity was in the range of 180-540 ng/zone for (1), 47-141 ng/zone for (2), 147-441 ng/zone for (3), 24-89 ng/zone for (4), 32-95 ng/zone for (5), 71-343 ng/zone for (6), 63-304 ng/zone for (7), 40-191 ng/zone for (8), 27-131 ng/zone for (9), 16-76 ng/zone for (10) and 45-219 ng/zone for (11). The intermediate precision over several months was below 6.7 % (n=3). The LODs of the anthocyanidins were much better compared to those for anthocyanins. The LOQs for (1) to (11) were below 90 ng/zone, most even below 30 ng/zone and for (9) and (10), the LOQ were even below 7 ng/zone. Radical scavenging as well as bioactivity properties were important complementary detection methods.
J. Food Comp. Anal. 41, 174-180 (2015). HPTLC fingerprint of red wines on silica gel with ethyl acetate - formic acid - acetic acid - water 10:1:1:2. Detection by dipping into NP reagent (1 g of diphenylborinic acid aminoethylester was dissolved in 200 mL ethyl acetate), followed by drying in cold air and dipping in PEG reagent (10 g of polyethylene glycol 400 is dissolved in 200 mL dichloromethane). Qualitative identification under UV 254 and 366 nm. Precisions of hRF values (% RSD) of three selected zones on two plates was below 0.02 %.
phytochemistry and pharmacology
J. Ethnopharmacol. 194, 30-56 (2016). Review of information on the ethnobotany, phytochemistry, pharmacological research and toxicity of Anogeissus species, including the application of HPTLC for the quantitative investigation of gallic acid, ellagoc acid as well as flavonoids like quercetin and rutin.
J. Planar Chromatogr. 30, 264-270 (2017). HPTLC of quercetin (1), apigenin (2) and kaempferol (3) in the stem bark of C. macleodii, C. rothi and C. dichotoma on silica gel with toluene ‒ ethyl acetate ‒ glacial acetic acid ‒ formic acid 10:10:1:2. Quantitative determination at UV 254 nm. The hRF values for (1) to (3) were 64, 66 and 71. LOD and LOQ were 9 and 29 ng/zone for (1), 30 and 92 ng/zone for (2) and 57 and 173 ng/zone for (3), respectively. The intermediate precision (n=6) was below 2 % for (1) and (2).
J. Ethnopharmacol. 232, 135-144 (2019). HPTLC of hesperidin in Citrus reticulatae pericarpium on silica gel with ethyl acetate – formic acid – acetic acid – water 15:1:1:2. Qualitative identification at UV 275 nm. The hRF value for hesperidin was 26.
Biochemical Systematics and Ecology 14, 79-80 (1986). Two dimensional TLC on polyamide with 1) water - butanol - acetone - dioxane 70:15:10:5 and 2) benzene - MEK - methanol - water 55:22:20:3. The air-dried chromatograms are sprayed with 0.1 % aminoethyl diphenyl borate. Identification of kaempferol, quercetin, isohamnetin. The two-dimensfonal chromatographic pattern of 37 plants examined were found similar.
