The natural extracts of plants are an important source for the identification of new biologically active compounds with possible applications in the pharmaceutical field. Phytotherapy embraces especially the isolation from herbs, of compounds with unique chemical structures, which are considered to be pharmacologically active. Recent statistics show that, on an annual basis, there are identified over 1500 new compounds from different species of plants, and about one quarter of prescription drugs contain substances of plant origin.

Although globally there are many studies on natural products, research in this area continues to be of great latent potential, in part due to the existing and still unexploited, potential and perspective development of new opportunities to recovery in major industrial areas and because of their socio-economic impact. A large number of plant extracts that have been used in the traditional medicine have also applications nowadays, both in the pharmaceutical and food industries (Busquet et al., 2005 [1]).
