生物活性

Tussilagone, a major active component in Tussilago farfara, has anti-inflammatory effect. Tussilagone ameliorates inflammatory responses in dextran sulphate sodium-induced murine colitis. Tussilagone inhibits the inflammatory response and improves survival in cecal ligation and puncture (CLP)-induced septic mice[1][2].

体外研究
(In Vitro)

Tussilagone suppressed the expression of the inflammatory mediators, nitric oxide and prostaglandin E2, and the inflammatory cytokines, tumor necrosis factor-alpha (TNF-α) and high-mobility group box 1 (HMGB1), in lipopolysaccharide-stimulated RAW 264.7 cells and peritoneal macrophages. Tussilagone also reduced the activation of the mitogen-activated protein kinases and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) involved in the activation of various inflammatory mediators in activated macrophages[1].

体内研究
(In Vivo)

Tussilagone administration (1 mg/kg and 10 mg/kg) produced decreased mortality and lung injury in CLP-activated septic mice. Augmented expression of cyclooxygenase (COX)-2 and TNF-α in pulmonary alveolar macrophages of septic mice were attenuated by tussilagone administration[2].
