Ocimum basilicum is known in Brasil as Manjericão and in countries of spanish language as albahaca. It is largely used in traditional medicine to bronchitis, coughs, sore throat, headache, stomach cramps, nausea, general pain and antiseptic. It can also be used in foods and flavorings [1]. It is among the plants that contain high concentrations of the defense compounds of the phenylpropene class (eugenol, chavicol, and their derivatives) [2-5]. It has been recognized as important spices for human consumption (e.g. cloves) and has high economic value. Source: R. J. C. Lima1, A. J. D. Moreno*1, E. M. Diniz1, R. S. G. Oléa2, J. M. Sasaki3, J.
