Reactive oxygen species (ROS), such as superoxide anion (O2-), hydrogen peroxide (H2O2), and hydroxyl radical (HO•), consist of radical and non-radical oxygen species formed by the partial reduction of oxygen. Cellular ROS are generated endogenously during mitochondrial oxidative metabolism as well as in cellular response to xenobiotics, cytokines, and bacterial invasion.

ROS also activates MAPK pathways by the direct inhibition of MAPK phosphatases. Through PTEN, the PI3K pathway is subject to reversible redox regulation by ROS generated by growth factor stimulation. The activation of autophagy may be a cellular defense mechanism in response to ROS.

    Calenduloside E
    		99.07%
    Calenduloside E is a pentacyclic triterpenoid saponin that can be extracted from the bark and roots of Aralia ovata, and has anti-inflammatory and anti-apoptotic activities. Calenduloside E alleviates atherosclerosis by regulating macrophage polarization, improves mitochondrial function by regulating the AMPK-SIRT3 pathway, and alleviates acute liver injury. In addition, Calenduloside E promotes the interaction between L-type calcium channels and Bcl-2 related apoptosis genes, inhibits calcium overload, and alleviates myocardial ischemia/reperfusion injury. Calenduloside E also improves non-alcoholic fatty liver disease by regulating heat shock-dependent pathways, and inhibits ROS mediated JAK1-STAT3 pathways to reduce cellular inflammatory responses.
