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.

Detection by spraying with 5 % vanillin - sulfuric acid reagent (mixture of 2.5 g vanillin, 45 mL ethanol, and 5 mL concentrated sulfuric acid), followed by heating at 105 °C for 5 min. Antibacterial assay was performed by dipping the plate into a cell suspension culture (Brain heart infusion broth and brain heart infusion agar in the ratio of 9:1), followed by incubation at 35 °C for 16 h and immersion into 0.2 % MTT solution for 3s, followed by incubation at 35 °C for 3h. Plates were scanned at 546 nm. The hRF values for thymol and carvacol were 88 and 78, respectively.

      Analytical Chemistry - An Indian Journal 8(1), 77-81 (2009). An HPTLC method is reported for estimation of lupeol and beta-sitosterol in the whole plant powder of Asteracantha longifolia (Acanthaceae). The proposed method was also employed for estimation of beta-sitosterol in herbal formulation containing Asteracantha longifolia. Methanolic extracts of the sample were used for chromatography. HPTLC on silica gel with toluene - ethyl acetate - methanol 75:15:7. Derivatization with Liebermann-Burchard reagent. Densitometric quantification at 366 nm. The concentration of lupeol and beta-sitosterol was 0.162 mg/g and 0.045 mg/g, respectively in the whole plant, while the concentration of beta-sitosterol was 0.039-0.048 mg/g in the formulation. The method was suitable for the quality control of the herbal formulation.
