%X 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.
