The present study describes for the first time the in vitro properties of Iris pseudopumila flowers and rhizomes extracts and their constituents. The methanolic extract of rhizomes showed significant anti-inflammatory activity through inhibition of NO production in the murine monocytic macrophage
The microglial activation plays an important role in neurodegenerative diseases by producing several proinflammatory cytokines and nitric oxide (NO). We found that three types of isoflavones and their metabolites that are transformed by the human intestinal microflora suppress lipopolysaccharide
