EFFECT OF OLIVE LEAVES BOILED EXTRACTS ON SOME

Abstract

The aim of this study was to investigate the effect of boiled extracts of Olive leaves on some Physiological and Productive Parameters in Males and Female Rabbits as glucose and lipid profile , as well as , their reflection on food intake , feed efficiency .The study was carried on rabbits (8-10 weeks old) divided .into 3 groups ( males) and 3 groups (females) . The1st group was drenched with distilled water and served as control group , the 2nd group was treated with Olive leaves boiled extract (2500 mg/kg B.w.t.) orally daily for 10 weeks . To determine the hypoglycemic effect per se of Olive leaves animals in the 3rd group were treated with Daonil (200 g/kg B.w.t.) orally daily for 10 weeks .Then blood obtained at the end of 10th weak of treatment . Results showed a significant decrease in blood glucose level in the treated groups .These effects were associated with a significant decrease in food intake with a tendency to increase body weight and a significant improvement in feed efficiency . The response was better in females than in males .Treatment with Olive leaves boiled extract caused a significant decrease in cholesterol level in male rabbits , and produced a significant increase in HDL-C in both sex , while it caused a significant decrease in LDL-C in males, These alterations in HDL-C and LDL-C were reflected in the significant improvement of risk ratio . To determine the duration of the effective hypoglycemic effect of the Olive leaves extract , a separate experiment was carried out on both sex ,the hypoglycemic effects continued significantly for 12 hrs in the Olive leaves treated on males and females , In general , the olive leaves effects was paralled to those of Daonil , this observation will sustain the suggestion that the Olive leaves Posses an insulin – like compounds , and the variations observed in the present study may due to the presence of several compounds in Olive leaves which enhances its effects in this regard .
