title: Allelopathic potential ofPiqueria trinervia (Compositae) and piquerols A and B.
abstract: Bioassays were carried out to test extracts of roots and leaves ofPiqueria trinervia and solutions of piquerol A and B, in order to appraise their allelopathic potential. Leaves seem to have greater concentrations of inhibitory compounds than roots. Both piquerol compounds show strong biological activity, but piquerol A is the more active.
