Abstract

Abstract: Tea is a natural healthy beverage and recent medicinal researches have been proven that teas have the neuroprotection function. In the neuroprotective effects of tea, catechins, L-theanine and caffeine work together to modulate the nervous system especially central nervous system in a multi-targets way through multiple pathways. Tea showed the free radical Scavenging function via the antioxidative roles. Besides, it showed the function of modulation the neurotransmitters as glutamic acid, γ-aminobutyric acid and acetylcholine etc. and their related receptors, prevention of tau protein phosphorylation and intracellular calcium overloads, regulation of protein kinase C signal transduction pathway, modulation of inflammatory factors, elevation of the neurotrophic factors’ level, elimination of vascular risk factors and attenuation of neuron apoptosis. Recent progress on the neuroprotective effects of tea was reviewed in this paper.

Key words: tea, active component, antioxidation, neuroprotection
