      Assessing the authenticity of absinthe using sensory evaluation and HPTLC analysis of the bitter principle absinthin
      D. LACHENMEIER (Chemisches und Veterinaeruntersuchungsamt, Karlsruhe, Germany, lachenmeier@web.de)

      Food Res. Int. 40, 167-175 (2007). HPTLC of absinthin in absinthe beverage (from the wormwood plant Artemisia absinthium L.) on silica gel with acetone - acetic acid (98 %) – toluene – dichloromethane 1:1:3:5. Detection by dipping into a solution of acetic anhydride – sulphuric acid – ethanol 1:1:10, followed by heating for 5 min at 104 °C. Quantitative determination by absorbance measurement at 554 nm. The hRf value of absinthin was 64 and selectivity regarding matrix was given. Linearity was between 0.1 and 10 g/L. The precision was better than 13.5 % (intraday) and 15.8 % (interday). The limit of detection and quantification for absinthin was 0.05 and 0.11 g/L, respectively.

      Don using a validated high-performance thin-layer chromatographic method. J. Planar Chromatogr. 31, 220-229 (2018). Quantitative TLC of betulin (1), lupeol (2), oleanolic acid (3), and betulinic acid (4) in the bark, leaves, and roots of Betula utilis on silica gel with n-hexane ‒ ethyl acetate 4:1 for (1) to (3), and with toluene – ethyl acetate 7:3 for (4). (1) to (3) were detected by dipping into ceric ammonium sulfate reagent, followed by heating at 105–110 °C for 5 min. Compound (4) was detected by spraying with Liebermann‒Burchard reagent, followed by heating at 105–110 °C for 5 min. Quantitative determination by absorbance measurement at 500 nm for (1) to (3) and 550 nm for (4). The hRf values for (1) to (4) were 59, 71, 48 and 71, respectively. Linearity was in the range of 2.5-10 μg/zone for (1) to (4). The intermediate precision was below 4 %. The LOD and LOQ were 175 and 532 ng/zone for (1), 166 and 504 ng/zone for (2), 396 and 1201 ng/zone for (3) and 109 and 330 ng/zone for (4), respectively. Average recoveries for (1) to (4) were 98.9, 99.3, 99.3 and 99.2 %, respectively.
