Plants of the genus Rubia (Rubiaceae) are used traditionally in European and Asian countries as drugs and are included in preparations such as Cystenal, Cystone, and Madder Extract. Greater than 150 naphthoquinones, anthraquinones and their glycosides, iridoids, terpenes, and hexapeptides have been isolated from these plants. Many of these possessed antitumor, antiseptic, anti-inflammatory, antioxidant, hepatoprotective, and gastroprotective properties [1, 2, 3, 4, 5].
A complex of anthraquinones that exhibited pronounced anti-inflammatory properties and prevented the development of kidney stones in animals was isolated from R. cordifolia cell culture [6, 7]. In continuation of research on biologically active quinones, we studied for the first time the quinoid composition of R. jesoensis (Miq.) Miyabe et Miyake roots.
The plant was collected in southern Primorskii Territory, RF, on the shores of Troits Bay, Peter the Great Bay, during full flowering (July 2012). The species was...
