Abstract: AIM: To investigate the protective effects of total of flavone C (TFC) on acute cerebral ischemia in mice and focal cerebral ischemia in rats.METHODS: The occlusion of bilateral common carotid arteries with vagus nerves in mice was used for make the acute cerebral ischemia models. The survival time and the death rate were observed. The permanent occlusion of the proximal of the right middle cerebral artery (MCA) was used for make the focal cerebral ischemia models. The extent of neurological deficits was observed, and the infarct area was measured by NBT staining technique. The activity of LDH and the content of MDA and NO in the ischemic cerebral cortex were determined.RESULTS: TFC of 80 and 40 mg·kg^-1 prolonged the survival time and decreased the death rate of mice with acute cerebral ischemia injury. TFC of 60, 30, and 15 mg·kg^-1 ameliorated neurologic deficits score and the infarct size of rats with MCAO.CONCLUSION: TFC provides significant protective effects against cerebral ischemia injury.
