Preparations based on Rumex confertus Willd. (Polygonaceae) root possess laxative, anti-inflammatory, hemostatic, bactericidal, hypotensive, sedative, and antitumor properties [1, 2, 3]. However, they have yet not found broad application in scientific medicine. In our opinion, this situation can be explained by the inadequate understanding of the chemical composition of R. confertus. In particular, regulations (VFS 42-1007-81) on R. confertus root do not require normalization of the raw material quality with respect to the active ingredients [4]. Furthermore, systematic structural studies of anthraquinones using NMR spectroscopy are missing for several of the anthracene derivatives [5, 6, 7, 8].

The goal of our work was to study the constituent composition of anthraquinones and naphthalene derivatives in R. confertus roots.

We studied roots of the plant that were collected in May 2011 in the vicinity of Samara. Air-dried roots (200 g) were extracted exhaustively by EtOH (70%),...
