en پژوهشي Research Article The methanolic extract of leaves of Turnera ulmifolia L was evaluated for its effect on blood glucose in alloxan-induced diabetic and euglycemic rats. The extract were administered at three doses of 100, 200 and 400 mg/kg, p.o. Glibenclamide (10 mg/kg, p.o.) was used as standard for control group. In euglycemic rat, extract were administered at three doses of 100, 200 and 400 mg/kg, p.o. Extract at 400 mg/kg and glibenclamide significantly reduced blood glucose level in normal and alloxan-induced diabetic rats and raised the liver glycogen content significantly. This indicates that the leaves extract of Turnera ulmifolia L posses anti-hyperglycemic activity. 77 0 http://ijpt.iums.ac.ir/browse.php?a_code=A-10-100-199&slc_lang=en&sid=1 D.
