Abstract

Two new oxanthrone C-glycosides, patientosides A (14) and B (15), together with three known ones (11-13), were isolated from Rumex patientia. Their structures were identified on the basis of spectroscopic methods. The absolute configuration for 14 and 15 were deduced by analysis of their CD spectra and comparison with those of known similar compounds. Compounds 11-15, and 14 known anthraquinones (1-4, 6-10, 16-20) previously isolated from Rumex nepalensis, Rumex hastatus, and endophytic Aspergillus fumigatus, respectively, as well as a commercially available compound rhein (5) were evaluated for their inhibitory effects on IL-6 and extracellular matrix production in mesangial cells.
