The photodegradation of ibuprofen (IBP) in aqueous media was studied in this paper. The degradation mechanism, the reaction kinetics and toxicity of the photolysis products of IBP under UV-Vis irradiation were investigated by dissolved oxygen experiments, quenching experiments of reactive oxygen species (ROS), and toxicity evaluation utilizing Vibrio(More)
Endothelial injury has been implicated in the pathogenesis of many cardiovascular diseases, including thrombotic disorders. Hyperin (quercetin-3-O-galactoside), a flavonoid compound and major bioactive component of the medicinal herb Apocynum venetum L., is commonly used to prevent endothelium dysfunction. However, its mode of action remains unclear. To the(More)
The adulteration of dietary supplements with drugs is potentially dangerous for human health. In this study, a method was used to test simultaneously for the presence of three synthetic PDE-5 inhibitors (sildenafil, vardenafil and tadalafil), and sibutramine and its two major metabolites (N-desmethylsibutramine and N-didesmethylsibutramine) using(More)
The vascular endothelium is important in the physiological homeostasis of blood vessels. Increasing evidence demonstrates that oxidative stress‑induced endothelial damage is involved in the pathogenesis of several cardiovascular diseases, including atherosclerosis. Hyperoside, one of major active components from Apocynum venetum L. (Luo‑Bu‑Ma), which is a(More)
