Ethnopharmacological Relevance: Centaurium erythraea Rafn (CE), Artemisia herba-alba Asso (AHA) and Trigonella foenum-graecum L. (TFG) are traditionally used to treat type 2 diabetes in Algeria, previous studies have found that extracts of these plants were effective to treat or prevent experimental diabetes induced by high-fat diet (HFD).

Aim Of The Study: Describe the additional effects of these extracts on lipid tissue deposition in HFD.

Materials And Methods: Male C57BL/6J mice were fed with HFD to induce type 2 Diabetes. Groups of mice were given plant extracts orally at 2g/kg/bodyweight daily for 20 weeks during establishment of diabetes, or for 18 weeks after confirmation of diabetes at the 17th week. Liver and other tissue samples were stained with Oil Red O.

Results: Liver steatosis was confirmed with HFD. CE, AHA and TFG extracts improved liver steatosis by the end of the preventive (20 weeks) and curative periods (35 weeks). This was most marked for CE extract (p<0.05), less so with TFG and AHA. No steatosis was found in other tissues.

Conclusion: CE extract had a clear hepatoprotective effect in this mouse model of diet-induced type 2 diabetes. AHA and TFG had a minimal or no significant effect on steatosis. Beyond its effect as an antidiabetic agent, CE may also be promising to prevent or treat non-alcoholic liver steatosis.
