Abstract

Weeds and wild plants are a source not yet exploited to obtain future phytosanitary products. These have different characteristics that make them a very attractive starting material as they are: many are edible, have several properties (so they are traditionally used in folk medicine), survive and prevail fret others, are abundant and have no economic value. Research its allelopathic properties and active principles will contribute to the expansion of scientific knowledge of this flora within the framework of a more sustainable ecological control that respects the environment and biodiversity. Thus, the objectives of this project are the isolation, structural determination and identification of pure products directly related to bioactivity levels. And determine the activity levels of the pure compounds. (AU)
