TLC of betamethasone, dexamethasone, hydrocortisone, prednisolone and prednisone on silica with ethyl ether - dichloromethane - water - methanol 15:77:1.2:8. Detection under UV 254 nm.
J. Planar Chromatogr. 16, 268-270 (2003). TLC of the Z and E diastereomers of the O-methyloximes of testosterone and 17a-methyltestosterone on silica gel with ether - petroleum ether (30-60°C) 1:1. The RF values of these compounds could be rationalized by a quantitative structure-property relationship (QSPR) using one topological/topographical index.
J. Planar Chromatogr. 31, 72-78 (2018). HPTLC of equol in ethanolic cattle manure extract on RP-18 with n-hexane – ethyl – acetate – acetone 9:3:2. Detection by planar yeast estrogen screening (pYES) by dipping into a yeast suspension, followed by incubation at 30 °C for 4 h. After incubation, the plate was dried in a 37 °C incubator for 15 min and dipped into the combined reaction buffer followed by incubation at 37 °C for 60 min and 90 % relative humidity. The combined reaction buffer was prepared by mixing 20 mL of buffer C (5.3 g of sodium phosphate dibasic and 0.4 g of potassium chloride were dissolved in about 490 mL water, the solution was adjusted with sodium hydroxide to pH 13, 0.5 g of benzalkonium chloride were added and the mixture was filled up to 500 mL) and 0.2 mL of a freshly prepared X-Gal solution (0.05 g/mL X-Gal in DMSO). Fluorescence evaluation under UV 366 nm. The hRF value for equol was 47.
J. Chromatogr. Sci. 34, 330-333 (1996). Two-dimensional TLC on silica with 1) chloroform - acetone 9:1, 2) cyclohexane - ethyl acetate - ethanol 31:8:1 for both directions. Detection by spraying with 95% ethanol concentrated sulfuric acid, heating at 110°C and visualization under UV. Quantification by HPLC.
simultaneous quantification of eight bioactive secondary metabolites from Cicer
microphyllum by high-performance thin-layer chromatography
J. Sep. Sci. 38, 4021-4028 (2015). HPTLC of eight natural products viz. stigmasterol (1), oleanolic acid-3-acetate (2), oleanolic acid (3), biochanin A (4), genistein (5), pratensein (6), chrysoeriol (7), and luteolin (8) in Cicer microphyllum on silica gel with n-hexane - ethyl acetate - formic acid 90:65:8. Detection by dipping into a solution of cerric ammonium sulfate reagent, followed by heating at 105 °C for 5 min. Quantitative determination by absorbance measurement at 366 nm. The hRF values for compounds (1) to (8) were 98, 89, 78, 70, 63, 42, 33 and 4, respectively. Linearity was in the range of 100-800 ng/zone for (1) to (8). LOD and LOQ were 60 and 90 ng/zone for (1), (5) and (8), 50 and 90 ng/zone for (2), 90 and 110 ng/zone for (3), 70 and 100 ng/zone for (4) and (6) and 80 and 110 ng/zone for (7). The intermediate precision was below 1.5 % (n=3). Recovery was in the range of 98-100 %.
