Parkinson’s disease （PD） is a common chronic neurodegenerative disease with movement disorders as the main clinical manifestation. The nuclear factor-erythroid 2-related factor 2 （Nrf2）/heme oxygenase-1 （HO-1） signaling pathway is closely associated with the occurrence and progression of PD. TCM flavonoid monomers （luteolin， rutin， etc.）， alkaloids （camptothecin， sinomenine， and alkaloids extracted from Uncaria rhynchophylla）， terpenes （tanshinone ⅡA， carvacrol， paeoniflorin）， phenols （ellagic acid， rosmarinic acid）， saponins （ginsenoside RK1）， and traditional Chinese medicine compounds （Wuzi yanzong pill and PD formula-2） can resist oxidative stress damage， inhibit inflammatory responses and abnormal aggregation of α-synuclein， and regulate neurotrophic factors by activating the Nrf2/HO-1 signaling pathway， thereby alleviating dopaminergic neuronal damage.
