These five compounds significantly inhibited lipopolysaccharide (LPS)-induced nitric oxide (NO) and prostaglandin E2 (PGE2) in a concentration-dependent manner. In the tumour necrosis factor-α (TNF-α) assay, only centaureidin and hydroxyachillin significantly inhibited the accumulation of TNF-α. These results indicate that these compounds may contribute to the anti-inflammatory properties of T. microphyllum. %~
