Eugenol was extracted and isolated from cloves leaves oil and further was screened by in vivo model of diabetic rats. Diabetic condition was induced with alloxan monohydrate (125 mg/kgbw, iv). Rats were divided into five groups: eugenol with 3 serial doses of 5 mg/kgbw (D1), 10 mg/kgbw(D2), 15 mg/kgbw (D3); positive control-glibenclamid 1.35 mg/kgbw (D4); normal control (D5) and negative control-CMC-Na 0,5% (D6). The treatments were performed daily for 15 days. Fasting blood glucose (FBG) level of D1 to D5 before treatment was404, 363, 319, 313, and 113 mg/dL, respectively; and after 15 days was reduced to be 294, 181, 97, 112, and 94 mg/dL, respectively. Statistically, blood glucose reduction of D1, D2, and D3 were significant (P>0,05) compared to positive control. D3 seems to be effective dose causinghypoglycaemic.

GEF products are organisms have undergone genetic modification using DNA recombining or genetic engineering technology. Many foods are genetically chan ged whole foods or contain ingredients derived from gene modification technology. The basic principle of genetic engineering technology is to manipulate the composition of DNA or to insert new genes into the structure of the recipient’s DNA. It means that the scientists inserted genes into the recipient’s living creatures can come from other living things. They still nowadays see those threats as a small trace is not to worry about them.
