OBJECTIVE: To evaluate the antihyperglycemic activity of Tecomaria capensis (T. capensis) Thunb. (Bignoniaceae) methanolic leaves extract (TCLE) using blood glucose level in normal fasted rats, glucose tolerance test and alloxan induced hyperglycemia models.
METHODS: TCLE (100, 300, 1 000 and 2 000 mg/kg body wt.) was given to rats orally to observe acute toxicity, and observed for 14 d. TCLE 200 and 400 mg/kg, and glibenclamide 0.6 mg/kg were given orally in all models.
RESULTS: Results demonstrated that the no mortality was reported even after 14 d. This indicates that the methanol extract is safe up to a single dose of 2 000 mg/kg body weight. TCLE (200 and 400 mg/kg p.o.) exhibited remarkable blood glucose lowering effect in blood glucose level in normal fasted rats, glucose tolerance and alloxan induced hyperglycemia model. Cholesterol and triglyceride also decreased in alloxan induced hyperglycemia model.
CONCLUSIONS: The results of this study exhibites that methanol extract of T. capensis possesses antihypergycemic activity and it may prove to be effective for the treatment of hyperglycemia.
