CBS 125. HPTLC of estrogen-active compounds in a migrate of a food contact material on silica gel with chloroform - acetone - petroleum ether 11:4:5. Planar Yeast Estrogen Test (P-YES) was performed by spraying 2 mL yeast cells onto HPTLC plates, followed by incubation at 30 °C for 3 h and spraying with 2 mL 0.5 mg/mL 4-methylumbelliferyl-beta-D-galactopyranoside and incubation for 20 min at 37 °C. The method was compared with microtiter bioassay (L-YES). P-YES was more sensitive than L-YES and results can be repeated upto one year later.
J. Planar Chromatogr. 35, 189-195 (2022). Planar yeast estrogen screen (pYES) of estriol, daidzein, genistein, 17β-estradiol, 17α-ethinyl estradiol, estrone, 4-nonylphenol and bis(2-ethylhexyl) phthalate on silica gel with cyclohexane - methyl ethyl ketone 2:1 or cyclohexane - cyclopentyl-methyl ether 3:2. Detection under UV light at 272 nm.
Anal. Bioanal. Chem. 413, 1321-1335 (2021). HPTLC of estrone (1), 17β-estradiol
(2), 17α-ethinylestradiol (3), 5α-dihydrotestosterone (4), and progesterone (5) in wastewater and surface water samples on silica gel with a mixture of dichloromethane, cyclohexane, and acetone in different proportions. Detection by spraying with 8 % sulfuric acid in ethanol, followed by heating at 105 ºC for 10 min. Qualitative identification under UV light at 310 nm. Yeast multi endocrine-effect screen was performed by spraying the HPTLC plates with a mixed suspension of genetically modified Arxula adeninivorans yeast strains, which contain either the human estrogen, androgen, or progesterone receptor. The HPTLC plates were incubated at 30 ºC for 18 h and at 100 % humidity. After incubation, densitometric evaluation at: 445/K460 nm, 475/K500 nm and 542/K560 nm to determine the fluorescence of the cyan fluorescent protein (CFP, gestagen), green fluorescent protein (GFP, androgen), and DsRed2 protein (estrogen), respectively. The hRF values for (1) to (5) were 21, 22, 29, 34 and 39, respectively.
J. Liq. Chromatogr. Relat. Technol. 42, 311-316 (2019). HPTLC of equol in cattle manure with methyl t-butyl ether - cyclohexane 1:1. The plate was scanned with a Time of Flight – Direct Analysis in Real Time – Mass Spectrometry (TOF-DART-MS) system. The hRF value of equol was 71. The LOD and LOQ for equol were 2.4 µg/zone and 4.5 µg/zone, respectively.
J. Planar Chromatogr. 26, 402-408 (2013). HPTLC of 17alpha-ethinylestradiol (1) and 17beta-estradiol (2) and estrone (3) on silica gel with chloroform - acetone - petroleum 11:4:5. The method was combined with the Yeast Estrogen Screen for the detection of estrogenic activity in aqueous samples. Quantitative determination by absorbance measurement at 366 nm. The hRf values of compounds (1) to (3) were 60, 50 and 67, respectively. LOD for (2) was 5 pg/zone.
Food Addit. Contam. 4, 415-427 (1987). HPTLC of 17ß-estradiol, DES, zearalanol (zeranol), zearalenone and their metabolites estrone etc. on silica with methyl chloride - methanol - isopropanol 97:1:2. Detection by exposure to iodine vapor and spraying with 1% starch solution. Detection limit, 4 ng.
J. Planar Chromatogr. 26, 395-401 (2013). HPTLC of 17alpha-ethinylestradiol (1), 17beta-estradiol (2) and estrone (3) on silica gel with chloroform - acetone - petroleum 11:4:5. The method was combined with the Yeast Estrogen Screen for the detection of estrogenic effects in sediment extracts of a river. Quantitative determination by absorbance measurement at 320 nm. The hRf values of compounds (1) to (3) were 74, 61 and 84, respectively.LOD and LOQ were calculated for the estrogenic model compound (1): LOD was 0.46 pg without prior development of the TLC plate and 0.48 pg after development, LOQ was 0.8 pg without development and 1.6 pg after development.
