ABSTRACT

Diabetes is a real public health problem in the world. It results in an abnormally high sugar level, measured in the blood several months apart. It is a chronic metabolic disease that occurs when the pancreas does not secrete insulin: insulin-dependent diabetes (type I) that usually affects the young person before age 30 or when the pancreas does not produce enough insulin and the secretion of it is deficient; form of diabetes found in adults and obese: non-insulin-dependent diabetes (type II). Indeed, faced with the dissatisfaction of modern remedies, the traditional phytotherapeutic approaches seem to reinforce an interesting potential, whose process of development, from the plant to the phytomedicine, through adequate scientific processes, could offer a credible alternative, for the communities.

Keywords: Chemical screening, total polyphenols, total flavonoids, medicinal plants, antidiabetic agents.
