      Quantification of steviol glycosides in food products, Stevia leaves and formulations by planar chromatography, including proof of absence for steviol and isosteviol
      J.P. WALD, Gertrud E. MORLOCK* (*Chair of Food Sci., Inst. for Nutritional Sci. & Interdisciplinary Res. Center (IFZ), Justus Liebig Univ. Giessen, Heinrich-Buff-Ring 26-32, 35392 Giessen, Germany, gertrud.morlock@uni-giessen.de)

      J. Chromatogr. A 1506, 109-119 (2017). HPTLC of seven important steviol glycosides on silica gel, which may degrade in food products under certain processing and storage conditions, and additionally as a sum parameter their reported breakdown products steviol and isosteviol. Detection with 2-naphthol and primuline reagent. Baseline separation of steviol and isosteviol was achieved after a plate cut and subsequent short development (two-step method). The HPTLC method was robust with regard to varying sample matrix loads, provided a high sample throughput (23 separations in parallel on one plate), and was fast (total analysis time of 1 h: 30 min application, 15 min separation and 15 min derivatization/densitometry, leading to 2.6 min per sample). The solvent consumption was low (0.4 mL per analysis) and accuracy of the densitometric quantification was good. Confirmation of the results with HPTLC-ESI-MS of only the zones of interest instead of matrix or background so that there was less need for MS cleaning. Hyphenation to Aliivibrio fischeri bioassay to obtain information on bioactive compounds in Stevia leaf extracts.
