Abstract
A compound isolated from root tissue extracts of Daucus carota L. showed antifungal activity towards Mycocentrospora acerina and Cladosporium cladosporioides. It was identified with the aid of u.v. and infrared spectroscopy, nuclear magnetic resonance and mass spectrometry as cis-heptadeca-1,9-diene-4,6-diyne-3,8-diol with the trivial name of falcarindiol. A concentration gradient in carrot roots varying from 93 μg/g fresh wt in periderm and pericyclic parenchyma to 2 μg/g in xylem parenchyma was demostrated. The ED 50 for inhibition of germination of chlamydospores of M. acerina was 31·8 μg/ml. The rôle of this compound in disease resistance is discussed.
