Title: Nuclear magnetic spectroscopy and research works

Abstract:

The use of natural products is the subject of several studies. Taking into account that the plant extracts offer the opportunity to recover bioactive molecules that can show therapeutic potential, they are engaged in the treatment of many diseases, further, their use as preservatives in aliment by replacing synthetic antioxidants. The study aims designed to examine the capacity of several solvents for the extraction of the main compounds from Capparis spinosa L. (Family Capparaceae) and to evaluate the antioxidant, antimicrobial activities of these extracts. Ethanol 80% was used to obtain crude extract from Capparis spinosa L. leaves, which was further partitioned by liquid-liquid extraction (LLE) using solvents with increasing polarity (hexane, diethyl ether, ethyl acetate, butanol, and water). The crude extract and the fractions were characterized by colorimetric methods, pyrolysis-gas chromatography (GC)-mass spectroscopy (MS), Fourier transform infrared.

Biography:

Mohamed Taieb BEN DHIA had obtained his University Doctorate in 1990 at the Faculty ofSciences of Tunis –Universiy of Tunis El Manar Senior Professor in 2009 and full Professorin 2016 in the same Faculty of Sciences. During 43 teaching years at the university, firstly, Ideveloped a nuclear magnetic spectroscopy (NMR-1D and NMR-2D) and thermodynamic approach concerning my research. Secondly in quality of Professor of Spectroscopy (NMR, IR, UV, Mössbauer) and Mass Spectrometry he is so solicited in national and international research evaluation committee as an expert. Concerning the pedagogic duty always he supervise Master Degree and Doctorate level in Physical-Chemistry and Theoretical approach using the theoretical Functional Density (DFT).
