      Microscopic and phytochemical comparison of the three Leonurus species L. cardiaca, L. japonicus, and L. sibiricus
      Anna PITSCHMANN, C. WASCHULIN, C. SYKORA, S. PUREVSUREN, S. GLASL* (*Department of Pharmacognosy, University of Vienna, Vienna, Austria; sabine.glasl@univie.ac.at)

      Planta Med. 83(14/15), 1233-1241 (2017). HPTLC of standards and methanolic extracts of L. cardiaca, L. japonicus and L. sibiricus (Lamiaceae) acidified with formic acid on silica gel with ethyl acetate – acetic acid – formic acid – water 100:11:11:26, in an automatic development chamber with 48 % humidity (20 min presaturation). Detection under white and UV light, before and after immersion in 1) anisaldehyde – sulphuric acid (followed by heating) for the detection of iridoids; 2) natural product reagent A for phenylpropanoids; 3) modified Dragendorff reagent (bismuth oxynitrate 0.17 %, sulfuric acid 3.5 %, glacial acetic acid 2 %, potassium iodide 4 %) for alkaloids. Ajugoside (hRF 29) and verbascoside (hRF 53) were found in L. cardiaca and L. sibiricus, but absent in L. japonicus. The opposite was true for leonurine (hRF 52), whereas stachydrine (hRF 14) was found in the three species. This method allows to distinguish L. japonicus from the other species, which have to be distinguished from each other through morphology.

      eupatorin, eupatorin-5-methylether, and sinensetin on silica gel with toluene – ethyl acetate – methanol 1181 with chamber saturation for 20 min to the migration distance of 70 mm. Detection under UV 254 nm and 366 nm. Densitometric evaluation by absorbance measurement at 254 nm. Elution of zones with TLC-MS Interface into a single mass spectrometer. Together with the already established sinensetin, scutellarein tetramethylether, eupatorin, and eupatorin-5-methylether were determined as specific markers suitable for the identification of Orthosiphon aristatus (Blume) Miq. by HPTLC. The presence of these four markers in the flavonoid profile is specific for Java tea.
