“…In this context, evidence has been published [3][4][5][6] that a wide array of plant-derived active principles, representing numerous classes of chemical compounds, demonstrate activity consistent with their possible use in the treatment of non-insulin-dependent diabetes mellitus (NIDDM). Among the classes of chemical compounds isolated from plants with documented biological activity are alkaloids, glycosides, galactomannan gum, polysaccharides, peptidoglycans, hypoglycans, guanidine, steroids, carbohydrates, glycopeptides, terpenoids, amino acids, and inorganic ions.…”
