RESUMO
<p><b>OBJECTIVE</b>To study hypoglycemic action of total flavone (GXTF) of Ampelopsis grossedentata from Guangxi by observing the effects of GXTF on blood glucose levels in many strain animal models.</p><p><b>METHOD</b>The blood glucose levels in many strain animal models were determined after oral administration, with the models of diabetes induced by alloxan, of hyperglycemic mice induced by epinephrine and glucose, and normal mice.</p><p><b>RESULT</b>GXTF had better therapeutical action on diabetes mice induced by alloxan, and could significantly lowered the blood glucose levels of hyperglycemic mice induced by epinephrine and glucose, but had no significant effects on blood glucose levels of normal mice. Acute toxicity test showed that the maximum oral dosage is 26.0 g.kg-1.</p><p><b>CONCLUSION</b>GXTF has better hypoglycemic effect on many strain animal models and toxicity is vary small.</p>
