      Development of a HPTLC method to profile the phytochemicals in Allanblackia parviflora (tallow tree) kernel and seed cakes
      W. SEFAH*, L. SEFAH, H. OFORI (*School of Science, Centre for Ecosystem Management, Edith Cowan University, Joondalup, Western Australia 6027, Australia, wilfred.sefah@kstu.edu.gh)

      J. Planar Chromatogr. 33, 33-41 (2020). HPTLC fingerprint of the kernel and seed of Allanblackia parviflora fruit (extracted with methanol - water 4:1) on silica gel with methanol - water - ethyl acetate 33:27:200. Detection by spraying with vanillic acid - sulfuric acid reagent (1 g of vanillic acid in 100 mL of 96 % ethanol, followed by the dropwise addition of 2 mL concentrated sulfuric acid). Different formulations of the derivatization reagent were investigated and the use of vanillic acid instead of the more frequently used vanillin provided a better result. Qualitative determination under UV 254 and 366 nm. Consistent hRF values of the main zones under UV 254 nm were 39, 35 and 12. For the derivatized plate, consistent hRF values of the main zones were 39, 34, 31 and 22.

MORITA** (*Laboratory of Natural Products Chemistry, Department of Chemistry, Faculty of Science, University of Dschang, Dschang, Cameroon; ** Institute of Natural Medicine, University of Toyama, Toyama, Japan; * mtene2001@yahoo.fr; ** hmorita@inm.u-toyama.ac.jp)

      Planta Medica 84(1), 59-64 (2018). A multi-step fractionation through silica gel column chromatography (CC) of a methanolic extract of Plectranthus africanus (whole plant, Lamiaceae) was monitored through TLC on silica gel with various solvent mixtures (n-hexane or dichloromethane with either acetone or methanol). Zones were detected under UV and further by spraying with sulfuric acid 20 % and heating at 100°C. For each fraction or TLC profile, the authors provide the CC gradient, the optimal proportions of the solvents used for the TLC mobile phase, as well as the RF values of the molecules isolated by this CC method: new abietane-type diterpenoids (plectranthroyleanones A, B, C), betulinic and oleanolic acids, heterosides of apigenin, rhamnetin and sitosterol.
