Cyperi Rhizoma, the rhizome of Cyperus rotundus L. (Family Cyperaceae), is a well-known functional food and traditional herbal medicine in Korea. It has been reported that Cyperi Rhizoma has antioxidant and free radical scavenging activities that play a major role in protection of neurodegenerative disorders, such as Parkinson's disease (PD). In the present study, the neuroprotective effects of a water extract of Cyperi Rhizoma (CRE) against 6-hydroxydopamine (6-OHDA)-induced neuronal damage were evaluated in an experimental model of PD. In PC12 cells, CRE showed a significant protective effect on cell viability at 50 and 100 mu g/mL. CRE inhibited generation of reactive oxygen species and nitric oxide, reduction of mitochondrial membrane potential, and caspase-3 activity, which were induced by 6-OHDA. CRE also showed a significant protective effect against damage to dopaminergic neurons in primary mesencephalic culture. These results suggest that CRE has neuroprotective effects against 6-OHDA-induced toxicity through antioxidant and anti-apoptotic activities in an in vitro PD model.
