Abstract/OtherAbstract:
The roots of the tropical tree Lonchocarpus oaxacensis afforded the 3-hydroxyflavanones jayacanol and mundulinol, as well as two flavanones, mundulin and minimiflorin. Flavonoids bearing 6,7-(dimethylpyran) and 8-(gammagamma-dimethyl allyl) substituents are characteristic for species grouped in the Minimiflori subsection. Therefore this subsection seems to be chemically and morphologically homogeneous. The antifungal activity of the four isolated compounds was tested against the wood rotting fungus Postia placenta, but only jayacanol was active.
