Phytochemical Investigation and Biological Evaluation of Disynaphia filifolia: A Novel Source of Tremetone in Asteraceae

Chemistry &Biodiversity, EarlyView.
ABSTRACT Chemical investigation of Disynaphia filifolia (Hassl.) R.M. King & H. Rob. (Asteraceae) led to the isolation of eight compounds, with tremetone being the major metabolite recovered. Tremetone has been suggested as the toxic compound in Ageratina altissima and Isocoma pluriflora, two species of the Asteraceae family. Although D.
