Hypoglycemic and hypolipidemic effects of the total triterpene acid fraction from Folium Eriobotryae.
For seeking the good natural material to develop new agent to treat diabetes, the total triterpene acid (TTA) fraction extracted from Folium Eriobotryae [leaves of Eriobotrya japonica (Thunb.) Lindl.] was evaluated for its hypoglycemic and hypolipidemic potential through normal, alloxan and streptozotocin-induced diabetic mice administered with graded oral doses (100, 200, 300 mg/(kg day)) for 7 or 14 days. The results showed that a dose of 300 mg/kg of TTA is the most effective dose to cause significant (p<0.01) hypoglycemic and/or hypolipidemic effects on normal, alloxan and streptozotocin-induced diabetic mice. This dose also significantly (p<0.01) lowered the glycosylated serum protein (GSP), total cholesterol (TC) and triglyceride (TG) level in severely diabetic mice. Furthermore, TTA increased the superoxide dismutase activity (SOD) and the serum insulin level of diabetic mice. These evidences indicated that the total triperpene acid fraction from Folium Eriobotryae has a high anti-diabetic potential along with a good hypolipidemic profile.
