生物活性

Picroside II, an iridoid compound extracted from Picrorhiza, exhibits anti-inflammatory and anti-apoptotic activities. picroside II alleviates the inflammatory response in sepsis and enhances immune function by inhibiting the activation of NLRP3 inflammasome and NF-κB pathways[1]. Picroside II is an antioxidant, exhibits a significant neuroprotective effect through reducing ROS production and protects the blood-brain barrier (BBB) after cerebral ischemia-reperfusion (CI/R) injury. Picroside II has antioxidant, anti-inflammatory, immune regulatory, anti-virus and other pharmacological activities[2].
