Abstract
| - Two new isoflavonols (1, 2) with insectantifeedant activity have been isolated from thetrifoliates of Trifolium subterraneum (Leguminosae).The structures of the compounds weredetermined by spectroscopic analyses. In addition, oct-1-en-3-ylarabinopyranosyl-(1→6)-β-glucopyranoside (3), a new metabolite, and phaselic acid(4), previously obtained from Trifoliumrepens, were isolated and characterized.
