摘要: The use of plants with therapeutic properties is as ancient human civilization, and for a long time, they were the main sources drugs. In recent years, there has been growing interest in alternative therapies especially those derived from plants. Natural products seem to be good chemical fungicides since numerous have potential control phytopathogenic fungi much prospect used fungicide. Several central Argentina evaluated on fungal species which attack crops agronomic interest. Different extracts Achyrocline satureioides, Aspidosperma quebracho blanco, Larrea cuneifolia, divaricata, Maytenus vitis-idaea, Minthostachys verticillata, Verbascum thapsus studied vitro vivo growth also their safety seedlings. From chloroform extract antifungal high capacity, three compounds could identified using chromatographic spectroscopic methods: Apigenine-7-methylether, nordihydroguaiaretic acid, 3,4-dihydroxy-3,4-dimethoxy-6,7-cyclolignan. latter compound described first time species.
