Journal of Applied Chemistry has retracted the article titled “Naturally Occurring Xanthones: Chemistry and Biology” [1]. The article was found to contain a substantial amount of overlapping material from previously published articles, including the following sources cited as [2–5]:(i)Kurt Hostettmann, Hildebert Wagner, “Xanthone glycosides,” Phytochemistry, Volume 16, Issue 7, 1977, Pages 821–829, ISSN 0031-9422, doi: 10.1016/S0031-9422(00)86673-X [2].(ii)L.
