Abstract
This work reports a green method to synthesize pectin‐capped selenium nanoparticles (PT‐SeNPs) using ascorbic acid as a reductant under mild conditions. Pectin was extracted from Tithonia diversifolia (Hemsley) A. Gray plant. Pectin played the role of a capping agent preventing the agglomeration of selenium nanoparticles. The synthesized PT‐SeNPs were characterized by UV–Vis spectrophotometry, EDX spectroscopy, TEM, DLS, FT‐IR, XRD, and TG‐DTA. The TEM and DLS techniques revealed monodispersed spherical selenium nanoparticles with sizes range of 100–200 nm. The amorphous PT‐SeNPs showed a phase transformation of nanostructure at 132 °C and a sublimation at 486 °C. The anti‐inflammatory of the obtained PT‐SeNPs was investigated in ethyl phenylpropiolate (EPP)‐induced rats. Rats treated with PT‐SeNPs exhibited ear edema inhibitions of 34.8%, 43.3%, and 46.7%, respectively at 30, 60 and 90 min after EPP injection.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
