      Planar yeast estrogen screen with resorufin-?-D-galactopyranoside as substrate
      D. SCHICK, W. SCHWACK* (*Inst. of Food Chem., Univ. of Hohenheim, Garbenstraße 28, 70599 Stuttgart, Germany, wolfgang.schwack@uni-hohenheim.de)

      J. Chromatogr. A 1497, 155-163 (2017). Development of a planar yeast estrogen screen for the determination of estrogen active compounds. Introduction of resorufin-?-D-galactopyranoside, providing the orange fluorescing resorufin after enzymatic cleavage, as the planar yeast estrogen screen (pYES) substrate to determine estrogen active compounds (EAC). For samples containing blue fluorescent components, this substance is better suited than the generally employed substrate 4-methylumbelliferyl-?-D-galactopyranoside, which delivered blue fluorescing 4-methylumbelliferone after enzymatic cleavage by the YES reporter ?-D-galactosidase. The mean LOD and LOQ was 3.5 and 6.5 pg/zone for 17?-estradiol (1) and 17?-ethinylestradiol (2), respectively; recoveries were close to 100% for (1) and (2) from spiked water samples in a concentration range of 2–20 ng/L.

      Rapid and sensitive determination of acrylamide in drinking water by planar chromatography and fluorescence detection after derivatization with dansulfinic acid
      A. ALPMANN, Gertrud MORLOCK* (*Institute for Food Chemistry, University of Hohenheim, 70593 Stuttgart, Germany, gmorlock@uni-hohenheim.de)

      J. Sep. Sci. 31, 71-77 (2008). HPTLC of acrylamide in drinking water on silica gel, derivatization in situ with 5-dimethylamino-naphtalene-1-sulfinic acid (1.6 µg/µL in methanol), followed by heating at 120 °C for 1 hour and developed with ethyl acetate. For fluorescence enhacement, the plate was dipped into a solution of 25 % polypropylene glycol in n-hexane and dried immediately. Quantitative determination by fluorescence at 366/>400 nm. Verification was based on HPTLC-ESI/MS, HPTLC-direct analysis in real time (DART)-TOF/MS and NMR. The hRf value of acrylamide (as 3-dansylpropanamide) was 69. Linearity was between 0.1 and 0.4 µg/L. Within-run precision and the mean between-run precision (n=3) were 4.6 and 11.0 %. The limit of detection and quantification for acrylamide was 0.025 and 0.083 µg/L, respectively. Recovery (by standard addition) was 96.4 %. The method showed comparable result with HPLC-MS/MS.

      Unprecedented sensitivity of the planar yeast estrogen screen by using a spray-on technology
      A. SCHOENBORN*, P. SCHMID, S. BRÄM, G. REIFFERSCHEID, M. OHLIG, S. BUCHINGER (ZHAW Life Sciences und Facility Management, Grüental, 8820 Wädenswil, Switzerland)

      J. Chromatogr. A 1530, 185-191 (2017). Development of a new spray-on method for applying yeast cells to HPTLC plates, leading to a much higher sensitivity of the planar yeast estrogen screen (p-YES), which can serve as a highly valuable and sensitive screening tool for the detection of estrogenic compounds in various sample matrices such as water and wastewater, personal care products and foodstuff. HPTLC of sample constituents and direct detection of estrogenic compounds by spraying with yeast cells. This resulted in much sharper signals compared to those in previous publications. Satisfying results were achieved using cultures with cell densities of 1000 FAU with reduced signal broadening, thus lower LOQ for estrogenic compounds, e.g. estrone 2 pg/zone, 17?-estradiol 0.5 pg/zone, 17?-ethinylestradiol 0.5 pg/zone and estriol 20 pg/zone. Demonstration of the possibility of the method to characterize profiles of estrogenic activity of wastewater samples with high quality and reproducibility by using native samples from wastewater or even surface water directly applied on HPTLC plates without the need for prior sample treatment.
