Antioxidant, Antifungal and Antitermite Activities of Residues from Hydrodistillation of Cymbopogon citratus, Eucalyptus camaldulensis and Mentha piperita
Assétou Sankara, Jean Claude Windéyolsidé Ouédraogo, Schémaéza Bonzi, Marie-France Thévenon, Yvonne Libona Bonzi-Coulibaly
Aromatic plant distillation produces residues rich in phenolic compounds known to be bioactive. In this context, residues from the hydrodistillation of Mentha piperita L., Cymbopogon citratus Stapf, and Eucalyptus camaldulensis Dehnh were chemically and biologically analyzed. The ethanol percentages (70%, 50%, and 30%) were evaluated by determ(...)

Glucosinolate profiling in Cleome gynandra L. aerial parts based on two extraction methods
Jonas Mano, Cedric Dicko, Jean Claude W. Ouédraogo, and Yvonne L. Bonzi-Coulibaly
Glucosinolates and their degradation products from Cleome gynandra L. are known for their beneficial effects in traditional medical use. As part of daily nutrient intake, the areal parts of this herb are cooked and consumed, whereas the residual water from boiling is discarded. However, it may contain valuable bioactive metabolites. Therefore,(...)

A manganese phthalocyanine histidine composite-modified carbon paste electrode as a biomimetic sensor for bisphenol A determination
Amadou Soukairatou Moustapha, Corneille Bakouan, Abdoulkadri Ayouba Mahamane, Boubié Guel
A biomimetic sensor was prepared from carbon paste electrode (CPE) modified with manganese phthalocyanine (MnPc) and histidine (His), and used for the determination of bisphenol A (BPA). The electrochemical biomimetic sensor (MnPc-His-CPE) gave significant current responses for BPA oxidation in comparison with CPE and MnPc-CPE, individually. T(...)
