African Shea Butter Properties Related to Common Extraction Technologies : A Review
Bertrand W. F. Goumbri1,2,3,4 · Thais Lomonaco Teodoro da Silva · Roland D. Marini · Rasmané Semdé · Touridomon Issa Somé · Sabine Danthine
Abstract
Shea butter is an important lipid material for food, cosmetic, and pharmaceutical industries. Most of the shea butter consumed in the world comes from Africa. The extraction protocol is not standardized among all regions of production. It can be done using either traditional or improved (semi-mechanical) processes. The quality of she(...)

Antioxidant activity study of Mareya micrantha leaves extracts using Differential pulse voltammetry
S. Siaka*1, K. A. J. N’zi1, Y. Soro1, B. Guel2
The rapid evaluation of antioxidant activities of plant extracts is of interest to many researchers in the field of phytochemistry. Electrochemical methods appear to be an alternative to the classic 2,2-diphenyl-1picryl-hydrazyl (DPPH) method, which is considered complex and constraining to be easily implemented. Indeed, using cyclic voltammet(...)

Low-Cost Synthesis of Alumina Nanoparticles and Their Usage for Bisphenol-A Removal from Aqueous Solutions
Ollé Rodrigue Kam, Issaka Garikoé, Corneille Bakouan, Boubié,
Gamma-alumina nanoparticles (γANPs) were obtained from a low-cost process by using natural bauxites. The γANPs materials were characterized by X-ray powder diffraction (XRPD), Fourier-transform infrared spectroscopy (FTIR), Brunauer–Emmett–Teller (BET) theory, scanning electron microscopy (SEM), atomic force microscopy (AFM), and were function(...)
