Effect of Noni Fruit Extract (Morinda citrifolia) on Glucose Intake to Diabetes Mellitus White Rat Muscle Tissue
Noni fruit (Morinda citrifolia) is one of the most common plants inIndonesia. This plant is often found in various regions in Indonesia, where theseplants are often in the form of shrubs or wild plants that grow in yards orplantations. This study aims to assess the effect of noni (Morinda citrifolia) fruitextract on blood sugar levels and the expression of GLUT4 protein in muscletissue which shows the potential of the test extract's ability to improve bloodglucose intake to cells so that it can maintain blood sugar regulation. Thisresearch was an experimental study that used white rats as research subject.Induction of diabetes was done by injecting alloxan at a dose of 110 mg/kg BWintraperitoneally; then the white rats were given 10% glucose to drink. Alloxan-induced white rats showed a very significant increase in blood sugar levels,where the use of the drug metformin was able to reduce blood sugar levelssignificantly. In white rats induced with diabetes mellitus, there was a decreasein GLUT4 levels in muscle tissue. The administration of metformin drugs or nonifruit extracts shows the ability to increase levels of GLUT4 protein. In conclusion,noni fruit extract affects lowering blood sugar levels in diabetes mellitus whiterats by increasing glucose intake to cells and tissues.
