Chemical substances, such as terpenes, phenolic compounds, cumarins, flavonoids, alkaloides, glycosides, tannins and quinones, originating from the secondary metabolisms of plants could initiate beneficial or harmful effects on other plants or other organisms (PINA- RODRIGUES; LOPES, 2001).
A number of investigators have shown that cumarins, flavonoids, terpenoids and a host of other secondary plant metabolites, including arginine and glutamic acid exhibit antidiabetic properties (Ross, 2001).
