Ficus deltoidea or Mas cotek is one of the common medicinal plants used in Malaysia has been claimed to have antidiabetic activity. However, scientific evidence to confirm its efficacy is still lacking. Thus, the present study was undertaken to evaluate the potential of ethanolic extract of Ficus deltoidea to reduce hyperglycaemia in streptozotocininduced diabetic rats at different prandial state. The results showed that, ethanolic extract of Ficus deltoidea significantly reduced fasting and postprandial hyperglycemia particularly after 4 and 6 hours of extract administration. Likewise, glucose tolerance activity was significantly improved in the presence of Ficus deltoidea ethanolic extract at a low dose, 100 mg/kg. It is suggested that ethanolic extract of Ficus deltoidea at particular doses, possess fasting and postprandial antihyperglycemic activity as well as glucose tolerance activity in streptozotocin-induced diabetic rats.

Hypoglycaemic and antihyperglycemic activity of oil palm Elaeis guineensis fruit extract on normal and Streptozotocin-induced diabetic rats was studied. The oil palm fruit extract (OPF) were administered orally at different concentrations (100, 200 and 500 mg kg-1 b.w.) in fasting and post-prandial rats. Hypoglycaemia was not observed in the group of normal rats treated with OPF. In fasting rats, OPF (500 mg kg-1 b.w.) has caused the blood glucose level (BGL) to reduce significantly. For post-prandial diabetic rats, the antihyperglycemic activity was observed after OPF treatment at concentrations 200 and 500 mg kg-1. Chronic OPF treatments (for 28 days) had increased the diabetic rat’s body weight and reduced BGL as well as improved plasma insulin secretion. The result of this study suggests E. guineensis palm fruit extract show evidence of antihyperglycemic properties from the reduction of the BGL in diabetic rats.
