Abstract Cerebral ischemia-reperfusion injury (CIRI) is one of the main diseases leading to death and disability. Studying the role and mechanism of drugs in mitigating CIRI is of great significance. In the present study, the effect of formononetin from Trifolium pratense L. on oxidative stress, energy metabolism impairment and inflammatory response after cerebral ischemia-reperfusion injury (CIRI) in mice were investigated. Formononetin was extracted from Trifolium pratense L. and was purified. The mice were treated with formononetin for six days. Then, the CIRI model was established. After 24 h of reperfusion, compared with model group, in formononetin group, the neurological deficit score, cerebral water content and cerebral infarction rate were significantly decreased, the brain tissue nitric oxide and malondialdehyde levels were significantly decreased, the brain tissue superoxide dismutase level was significantly increased, the brain tissue Na+-K+-ATPase, Ca2+-Mg2+-ATPase and Ca2+-ATPase activities were significantly increased, and the brain tissue tumor necrosis factor α, interleukin 1β and interleukin 6 levels were significantly decreased. In conclusion, formononetin from Trifolium pratense L. can reduce the oxidative stress, energy metabolism impairment and inflammatory response in brain tissues, thus mitigating the CIRI in mice.
