Resumen:
Abstract. In the course of a phytochemical study of L. mollis Cav. the previously reported compounds patuletin-7-O-glucoside 1, 12-hydroxy-13-en-xanthorrhizol 2, 11-en-13-hydroxy-xanthorrhizol 3, xanthorrhizol 4, 12,13-epoxy-xanthorrhizol 5, and 1-á-angeloyloxycarotol 6, were isolated. The EtOH extract of the aerial parts showed selective phytotoxic effects on S. halepense. Compounds 2 and 3 exhibited potent herbicidal activity on S. halepense. Additionally, at all assayed doses, compound 2 affected drastically the root growth.
