Abstract: Prepare mice model with diabetes caused by reducing adrenaline and with hyperglycemia caused by tetraoxypyrimidine, after lavaging normal mice, mice model with diabetes caused by reducing adrenaline and with hyperglycemia caused by tetraoxypyrimidine for 14 days with Anji white tea polysaccharide, their blood sugar level are tested to study the effect of Anji white tea polysaccharide on the blood glucose. The result shows that after 2 weeks, Anji white tea polysaccharide showed a very weak effect on the blood glucose level of normal mice. Different dose showed small difference compared with normal dose (P>0.05), it can distinctly reduce the blood glucose level of mice models with diabetes caused by reducing adrenalin, the different doses showed quite different effects on their blood glucose levels(P<0.01), and the effect of high dose is distinctly better than that of low dose. It can effectively reduce the blood glucose level of the mice with hyperglycemia caused by tetraoxypyrimidine. The fasting glucose of the 3 groups with different doses are quite different from that with tetraoxypyrimidine (P<0.01). The 3 kind of doses can all reduce the blood glucose level of the tested mice, with a better effect by a larger dose. Anji white tea polysaccharide showed an effective influence on reducing the sugar tolerance of the mice with diabetes mellitus and has reached the cure level of the NAEDs, but it doesn’t affect the BSL and sugar tolerance of normal mice.

Key words: Anji white tea, tea polysaccharide, distill, regulates blood sugar Level, sugar tolerance
