ABSTRACT:
The present invention relates to a composition comprising an extract ofDioscorea oppositahaving neuron-protective activity for preventing and treating brain disease. The extracts fromDioscorea oppositashow potent neuronal cell protective activity by inhibiting neuronal cell death caused by neuro-toxicity of glutamate and H2O2therefore it can be used as the therapeutics or health food for treating and preventing brain diseases.
