Nature has always produced almost every organic substance known. The plant kingdom is responsible for contributing with secondary metabolites administration; many of them offer a great added value due to their application in medicine, cosmetics, aliments and agrochemicals. Plants have their own defenses that normally protect them from other plants and predators.
These defenses have a chemical nature and, generally, involve substances of secondary metabolism (CROTEAU et al., 2000; PINTO et al., 2002).
