Anti-, Antioxidant Activities, and Oral Acute Toxicity of Organics Extracts from the Root Bark of Guill. and Perr.

(Fabaceae) is a medicinal plant from the traditional pharmacopeia of Niger used against gastrointestinal disorders and dysentery. This study was designed to assess the anti-, antioxidant activities, and oral acute toxicity of extract root barks of . The crude extracts were prepared by maceration using methanol, ethanol, dichloromethane, water-ethanol (30/70 v/v), and methanol-dichloromethane (1/1 v/v).

Photochemically-induced fluorescence dosage of non-fluorescent pyrethroid (Etofenprox) in natural water using a cationic micellar medium.

An analytical method based on the use of UV-irradiation to produce fluorescent derivatives from Etofenprox a non-fluorescent pyrethroid insecticide is described. The impact of cetyltrimethylammonium chloride (CTAC) micellar medium on the Etofenprox photochemically-induced fluorescence (PIF) is reported. Parameters influencing the sensitivity and repeatability of the PIF method have been optimized.
