Anthracene derivatlves in some species of Rumex L genus

Abstract

Eight anthracene derivatives (chrysophanol, physcion, emodin, aloe-emodin, rhein, barbaloin, sennoside A and sennoside B) were signified in six species of <em>Rumex</em> L. genus: <em>R. acetosa</em> L., <em>R. acetosella</em> L., <em>R. confertus</em> Willd., <em>R. crispus</em> L., <em>R. hydrolapathum</em> Huds. and <em>R. obtusifolius</em> L. For the investigations methanolic extracts were prepared from the roots, leaves and fruits of these species. Reverse Phase High Performance Liquid Chromatography was applied for separation, identification and quantitative determination of anthracene derivatives. The identity of these compounds was further confirmed with UV-VIS. Received data were compared. The roots are the best organs for the accumulation of anthraquinones. The total amount of the detected compounds was the largest in the roots of <em>R. confertus</em> (163.42 mg/g), smaller in roots <em>R. crispus</em> (25.22 mg/g) and the smallest in roots of <em>R. hydrolapathum</em> (1.02 mg/g)

Wild edible plants: Nutritional and toxicological characteristics, retrieval strategies and importance for today's society

“…Eight anthracene derivatives were described in six Rumex species (Table 7), including R. acetosa, R. acetosella, R. crispus and R. obtusifolius, and the highest levels were detected in the roots (Smolarz et al, 2011).…”

A New Ceramide (Rumexamide) and Other Chemical Constituents from &lt;i&gt;Rumex abyssinicus&lt;/i&gt; Jacq (Polygonaceae): Isolation, Characterization, Antibacterial Activities and Chemophenetic Significance

“…acetosa., R. acetosella L., R. confertus Willd., R. crispus L., R. hydrolapathum Huds. R. obtusifolius [41] and R. aquaticus [42], compounds 5 and 7 from R. japonicus [43], R. nepalensis [44], compound 8 from R. obtusifolius [45] and compounds 7 and 8 from R. acetosa [46]. Base to the fact that, anthraquinones represent one of the main classes of secondary metabolites isolated from the genus Rumex [14] [47], their presence in all of the above species allowed us to conclude that R. abyssinicus and the other species mentioned exhibit very close chemotaxonomic relationships.…”

“…In TM the leaves of R. acetosella are used by the native populations of North America as treatment for warts and bruises. The aerial parts contribute to amelioration of diarrhea and stomach disorders in North America and Hungary, while seeds are used to treat diarrhea and dysentery in Hungary (Chevalier, 1996;Shale et al, 1999;Foster et al, 2000;Wegiera et al, 2007;Vasas et al, 2015). An ethnobotanical survey of medicinal plants used in Turkey revealed that leaves of R. acetosella are used traditionally as an analgesic and diuretic (Cakilcioglu and Turkoglu, 2010).…”

“…The main chemical compounds in the genus Rumex are antraquinones (emodin, physcion, and chrysophanol in fruits and leaves, and sennoside A in fruits and roots), nepodin, and flavanoids (quercetin-3-O-glucoside) with important antioxidant activity, while the stilbenoids demonstrated to have a positive impact in cancer therapy and inflammatory diseases (Wegiera et al, 2007;Vasas et al, 2015).…”
