The main chemical compositions of tea flower were studied. It is the first time to determine the levels of protein, reducing saccharides and SOD activity in different blooming stages of tea flowers collected from three cultivars of Camellia sinensis with different picking time. Results showed that there were significant differences among cultivars and blooming stages, as well as the change of these chemical constituents along with time. Consequently we selected the right cultivar that has high protein, reducing saccharides or SOD activity and the fitting deflower time.

在上述体系中进行的SOD的活性研究中，没有发现表观超活性，估计是两方面的原因：一是囊泡周围低的介电常数同样也降低了SOD酶的活性，二是由于表面活性剂浓度较小，仅为0.5％左右，使得囊泡体积分数较小，不能与SOD酶发生充分有效的结合。

In the beginning, at the situation of high blood volume, if the blood glucose sufficient, the erythrocytic function of making ATP by glucose is normal, the free radical and the anti-free radical of the rat basicly keep balanced, erythrocytic deforming ability is not influenced greatly; while the erythrocytic function of making ATP degenerates in sport iron deficient erythrocyte formation and hemolysis, especially the former; and the vitalities of anti-free radical reduce greatly in blood, liver and Erythrocyte, the reducement of liver SOD vitality in the former and erythrocyte SOD vitality in the latter are more obvious, and the total blood SOD amounts reduce identically; The erythrocytic deforming ability reduces greatly too, but there is no obvious difference between the two groups, but the tendency of the inner-mechanism may be different needing to researching deeply later.
