Summary: | The preventive effect of the hydro-alcoholic extracts of
Artemisia herba-alba Asso (AHA), and
Centaurium erythraea Rafn (CE), two medicinal plants used in traditional treatment of diabetes in the north-eastern Algeria, were evaluated in animal models of type 2 diabetic induced with a standardised high fat diet (HFD).
Plant extracts were administered orally by gavage at a dose of 2
g/kg bodyweight daily for 20 weeks to male C57BL/6J mice fed HFD. Animals were weighed and plasma glucose measured weekly and insulin at the end of study using standard ELISA methods.
After 6 weeks, blood glucose levels increased in HFD control mice. At end of study (20 weeks) in groups treated with AHA or CE extracts
vs. HFD control group there was a significant reduction in mean (±SD) fasting blood glucose (respectively 108.0
±
42.0 and 120.4

vs. 183.1

ng/ml,

±
5.3, CE: 3.0
±
3.3
vs. HFD control 38.3
±
26.6,
p
<
0.05). The plant extracts had no effect on calorie intake or body weight.
AHA had been shown to have a hypoglycaemic effect in diabetes but this is the first demonstration of a preventive effect of AHA and CE on HFD-induced diabetes.
Extracts of
Artemisia herba-alba or
Centaurium erythraea opposed the effects of high fat diet on plasma glucose, insulin and triglycerides in C57BL mice, in line with traditional use to treat diabetes in man in Algeria. |
