      D. KRÜZSELYI, J. BAKONYI, P. OTT, A. DARCSI, P. CSONTOS, G. MORLOCK, Agnes MORICZ* (*Plant Protection Institute, Centre for Agricultural Research, Eötvös Loránd Research Network (ELKH), 1022 Budapest, Hungary,

      J. Agric. Food Chem. 69, 12686-12694 (2021). HPTLC of 2Z,8Z- and 2E,8Z-matricaria esters in European goldenrod (Solidago virgaurea) and E- and Z-dehydromatricaria esters in grass-leaved goldenrod (Solidago graminifolia) and showy goldenrod (Solidago speciosa) on silica gel with n-hexane − acetone 17:3. Detection by dipping into mycelium suspension of F. avenaceum and B. sorokiniana, followed by incubation in a vapor chamber at 21 °C for 48−72 h. The lack of visible white (F. avenaceum) or dark gray (B. sorokiniana) fungal mycelia indicated the inhibition zones on the bioautograms. Compounds were further analyzed by high-resolution mass spectrometry and nuclear magnetic resonance spectroscopy.

      On-surface autosampling for liquid chromatography – mass spectrometry
      A. MEHL, W. SCHWACK, Gertrud E. MORLOCK* (*Institute of Nutritional Science, and Interdisciplinary Research Centre for Biosystems, Land Use and Nutrition, Justus Liebig University Giessen, Giessen, Germany;

      J Chromatogr A, 1641, 462334 (2021). Validation of a newly built (using 3D-printing) and newly configurated on-surface multi-purpose autosampler, called “autoTLC−LC−MS system”, developed for orthogonal hyphenation of normal phase HPTLC with reversed phase HPLC and high-resolution MS. Details and protocols are given for the construction, installation and numerical control software programming of this autosampler. HPTLC of antibiotics cefoperazone (third-generation cephalosporin), clindamycin (lincosamide), erythromycin A (macrolide), ipronidazole (nitro-imidazole), nafcillin (penam), sulfaquinoxaline (sulphonamide), tiamulin (pleuromutilin), and trimethoprim (DHFR inhibitor) on silica gel without development. Bioassay with Bacillus subtilis: bacterial suspension was sprayed onto the plate, which was  horizontally incubated for 2 h at 37°C in a humid box; afterwards, the plate was sprayed with 0.2% MTT solution, incubated again for 30 min at 37°C, dried for 10 min at 50°C, and documented under white light. The image was uploaded as a template in the updated TLC–MS managing software, so that by clicking on the zones of the image showing antibacterial activity, the corresponding zones of the untreated plate, placed on a newly designed plate holder, were sequentially eluted by the round elution head of the automatic sampler into the RP-18 endcapped HPLC monolithic column connected to a Quadrupole-Orbitrap mass spectrometer. For the elution from the plate and HPLC separation, a gradient was used (flow rate 0.2 - 0.5 mL/min, depending on the step), with different proportions of two mobile phases: A) 0.1 % formic acid and 4 mM ammonium formate in water; B) 0.1 % formic acid and 4 mM ammonium formate in methanol. After separation in the column, antibiotics directly underwent electrospray ionization in positive mode (voltage 3.5 kV, capillary temperature 320 °C, probe heater temperature 350 °C) and were detected by HRMS. For validation, the achieved ranges were 2.1–14.1 % for intra-day and 2.5–16.1 % for inter-day precisions.
