      Anti-inflammatory flavanones and flavanols from the roots of Pongamia pinnata
      R. WEN, H. LV, Y. JIANG, P. TU* (*School of Pharmaceutical Sciences, Peking University, Beijing, China;

      Planta Med. 84(16), 1174-1182 (2018). The fractionation and purification steps (column chromatography, including reverse-phase HPLC) of an ethanolic extract of Millettia pinnata (= Pongomia pinnata, Fabaceae) roots were monitored by TLC on silica gel with n-hexane – ethyl acetate mixtures 4:1 - 2:1. Detection at 254 and 336 nm, and by spraying with sulfuric vanillin reagent followed by heating. The process allowed the isolation of 2 flavanols (including pongaflavanol), 1 flavanol ether and 26 flavanones (including derrivanone, griffinones, isoderricines, isoglabrachromene, isolonchocarpin, liquiritigenin, maxima flavanone A, ovalichromene B, ovaliflavanones, pinostrobin, pongachin, pongamone C, ponganone III).

      Identification of a collagenase-inhibiting flavonoid from Alchemilla vulgaris using NMR-based metabolomics
      Manuela MANDRONE*, A. COQUEIRO, F. POLI, F. ANTOGNONI, Y.H. CHOI (*Department of Pharmacy and Biotechnology, University of Bologna, Bologna, Italy;

      Planta Med. 84(12-13), 941-946 (2018). The activity-guided fractionation and purification steps (column chromatography and liquid-liquid partitions) of a hydromethanolic extract of Alchemilla vulgaris aerial parts (Rosaceae) were monitored by TLC on silica gel with ethyl acetate – acetic acid – formic acid – water 100:11:11:27. Detection at 254 and 336 nm, and by spraying with anisaldehyde reagent followed by heating. A flavonoid (quercetin-glucuronide) was isolated through this process.

      Identification, isolation and determination of biomarkers for quality control of Bush Tea (Athrixia phyllicoides)
      LL J. LEROTHOLI, S.K. CHAUDHARY, W. CHEN, C.G.L. VEALE, S. COMBRINCK, A. M. VILJOEN* (*MRC Herbal Drugs Research Unit, Department of Pharmaceutical Sciences, Tshwane University of Technology, Pretoria, South Africa;

      Planta Medica 84(12-13), 902-912 (2018). A dichloromethane extract of Athrixia phyllicoides aerial parts (Asteraceae) was eluted on a silica gel column with different mixtures of ethyl acetate and hexane or methanol. This fractionation was monitored on TLC silica gel layers, using the combinations of the same solvents as mobile phases. Detection by derivatization with Natural Product Reagent and PEG, and visualization at UV 254 nm. This allowed the grouping of the fractions into 13 profiles and the isolation of three hydroxy-methoxyflavones and a coumarate.

      Impact of Green Tea catechin ECG and its synthesized fluorinated analogue on prostate cancer cells and stimulated immunocompetent cells
      S. STADLBAUER*, C. STEINBORN, A. KLEMD, F. HATTORI, K. OHMORI**, K. SUZUKI, R. HUBER, P. WOLF, C. GRÜNDEMANN* (*Center for Complementary Medicine, Faculty of Medicine, University of Freiburg, Freiburg, Germany; ** Department of Chemistry, Tokyo Institute of Technology, Tokyo, Japan; *;; **

      Planta Medica 84(11), 813-819 (2018). Fluorinated analogues of epigallocatechin-gallate were purified after synthesis by extraction with ethyl acetate from the synthesis mixtures, followed by column chromatography or (for two pairs of isomers) by preparative TLC. This isolation (as well as monitoring of column elution for the other compounds) was performed by TLC on silica gel with mixtures of n-hexane and (less) ethyl acetate in several concentrations, allowing the separation of diastereoisomers (RF values and yields are given). No derivatisation, visualisation because of fluorescing agent in the layers. Structures were identified by NMR and HR-MS, but apart from the TLC.
