Protective effects of polydatin on multiple organ ischemia-reperfusion injury

Polydatin(PD), a natural active ingredient isolated from traditional Chinese herb Polygonum cuspidatum, is also found in daily foods such as grapes and red wine. It might play a potential therapeutic role in human health through its anti-inflammatory, anti-oxidant, anti-ischemia injury, anti-apoptosis, conditioning blood lipids and other effects, which makes it increasingly become a hotspot of research. Various studies have shown that PD has a protective effect in the ischemia-reperfusion injury of heart, lungs, kidneys, gastrointestinal tract, cerebra and other organs. However, the specific mechanism of action is less and not completely clear. In this study, we aim to review the protective mechanism of PD in the ischemia-reperfusion injury of various organs, and provide inspiration for future studies.
