Description Extensive phytochemical analysis of the CHCl3-soluble part of an ethanolic extract of branches and twigs of Broussonetia papyrifera led to the isolation of fourteen compounds, including a novel 5,11-dioxabenzo[b]fluoren-10-one derivative named broussofluorenone C (12). The isolated compounds 1-14 were characterized based on their NMR and HRMS data, and examined for their anti-inflammatory activities in LPS-stimulated THP-1 cells as well as for their cellular antioxidant effects. Compounds 7-10 and 12 showed inhibitory effects on NF-kappa B/AP-1 activation and compounds 7-9 were subsequently confirmed to suppress the secretion of both IL-1 beta and TNF-alpha in LPS-stimulated THP-1 cells more significantly than the prednisone used as a positive control. In the CAA assay, compound 10 exhibited the greatest antioxidant effect, greater than that of the quercetin used as a positive control. The results show possible beneficial effects and utilization of B. papyrifera wood in the treatment of inflammatory diseases as well as oxidative stress.
