      Evaluation of various biological activities of natural compounds by TLC/HPTLC
      A. HOSU, Claudia CIMPOIU* (*Department of Chemistry, Research Center for Advanced Chemical Analysis, Instrumentation and Chemometrics (ANALYTICA), Faculty of Chemistry and Chemical Engineering, Babes-Bolyai University 11 Arany Janos, Cluj-Napoca, 400028, Romania, ccimpoiu@chem.ubbcluj.ro)

      J. Liq. Chromatogr. Relat. Technol. 43, 305-318 (2020). Review of the application of TLC in the evaluation of different biological activities of natural compounds, focusing on antioxidant (using 2,2-diphenyl-1-picrylhydrazyl radical assay and decoloration of beta-carotene), enzymatic (using enzyme inhibition assays), antimicrobial (bioautographic assays) and hormonal (using yeast strains screening) activities.

      Imaging the unimaginable: Desorption Electrospray Ionization – Imaging Mass Spectrometry (DESI-IMS) in natural product research
      D. PARROT, S. PAPAZIAN, D. FOIL, Deniz TASDEMIR* (*Research Unit Marine Natural Products Chemistry, GEOMAR Helmholtz Centre for Ocean Research Kiel, 24106 Kiel, Germany; dtasdemir@geomar.de)

      Planta Medica 84(9/10), 584-593 (2018). A review with 120 references on DESI technique coupled with MS for natural products. Paragraph on sample preparation (9 references) compares analyte desorption surfaces: either directly from the biological sample, or indirectly from surfaces on which the sample had been imprinted. Direct desorption can be performed only from samples with hard, smooth and regular surfaces, or from cryosections, which are usual for animal tissues. For plants, indirect analysis is preferable because of their wax-rich, hydrophobic, absorbent and/or irregular surfaces. Imprinting of plant organs and tissues can be performed either on glass (however with a very rapid ablation of the analytes from its surface), or on sorbent material, like TLC silica gel or porous polytetrafluoroethylene (PTFE). While PTFE layers are reported as more expensive and better in terms of reproducibility and quantitative analysis, both TLC and PTFE layers have similar performance for analyte retention until desorption.
