This method was suitable for the routine determina- tion of catechins composition and content in tea.

Tea catechin is a high effective and low toxic scavenger of free radical and has various pharmacological and healthy functions Its absorption,distribution,biologic transformation and excretion were summarized in this paper,so as to provide some theoretical reference for further study of tea catechi

Studies on effects of tea catechins on neuron and Ca~(2+) concentration in the brain of cerebral ischemia and reperfusion rats;

The antioxidant activity of tea catechins′ oxy polymers(TCOP) was investigated in both soy liposomes and lard oil systems by Na 2S 2O 3 I 2 titrimetric method.

object: The protective effects of tea catechins on the injury of cerebral ischemia and reperfusion in rats were observed with rat cerebral ischemia and reperfusion model produced by bilaterally clamping the common carotid arteries and vagus nerves for 60 min and then removing the occlusion for 30 min.

We can locate the loss of CO2 and C2H2O in MS2 spectra from EC/C to A ring and B ring,respectively.

Green tea catechin(GTC) is the most active component of green tea.
