      Direct bioautography hyphenated to direct analysis in real time mass spectrometry: Chromatographic separation, bioassay and mass spectra, all in the same sample run
      T. T. HÄBE, Maryam JAMSHIDI-AIDJI, Jennifer MACHO, Gertrud E. MORLOCK* (*Chair of Food Sci., Inst. of Nutrit. Sci., and Interdiscipl. Res. Center (iFZ), Justus Liebig Univ. Giessen, Heinrich-Buff-Ring 26-32, 35392, Giessen, Germany,

      J. Chromatogr. A 1568, 188-196 (2018). Application of an advantageous combination, the desorption-based direct analysis in real time mass spectrometry (DART-MS) immediately after direct bioautography (DB), i.e., in the presence of microorganisms, bioassay medium and substrate reagent. The method offers a straightforward and efficient mass spectrometric detection of bioactive analytes within the bioautogram. It discriminated microorganism cells and highly polar bioassay medium ingredients which could otherwise stress the MS system. Investigation of DB-DART-MS for bioactive compounds in cosmetics using the Bacillus subtilis and Aliivibrio fischeri bioassays for detection of Gram-positive and Gram-negative antimicrobials, respectively, and the planar yeast estrogen screen for detection of estrogen-effective compounds. Study of the influences of three different bioassay matrices on the analyte response and DB-DART-MS performance on different layers (NP and RP) on the example of parabens in hand creams. Ion suppression was enhanced with increasing culture medium complexity. The mass spectrometric quantification by DB-DART-MS at the ng-level in situ each different bioautogram was verified by comparison to HPTLC-DART-MS. The total paraben content of hand creams 1 and 2 was 0.17–0.20% and 0.30–0.34%, respectively, depending on the method used. It proved that DB-DART-MS is a reliable qantitative bioanalytical hyphenation.

      J. Liq. Chromatogr. Relat. Technol. 41, 1052-1065 (2019). Review of the following topics for the period of November 1, 2016 to November 1, 2018: sample preparation for TLC pesticide analysis; lipophilicity and retention studies for the study of biological activity; new reagents for pesticide detection; HPTLC-effect directed analysis on the surface of the layer; TLC-Raman spectrometry for the analysis of thiabendazole, triazophos, and phosmet residues; TLC analysis of radiolabeled pesticides; methods for the separation, detection, and qualitative and quantitative determination of pesticide residues; determination of pesticides in commercial products and the use of TLC for pesticide degradation studies. The review highlighted the isolation, characterization, and determination of less hazardous and less toxic biopesticides from plants, bacteria, fungi, and soil as the most active application area of pesticide TLC today.
