抄録

Nine autifungal stress compounds were isolated and identified from the roots of adzuki bean (Vigna angularis) that had been treated with Cephalosporium gregatum type B, which is an avirulent strain of a pathogenic fungus causing brown stem rot disease on the host plant. These compounds were a novel isoflavanone dihydrowighteone, seven isoflavonoids.known as dalbergioidin, phaseol, 2'-hydroxygenistein, lupiwighteone, lupinalbin A, (3R)-(-)-vestitol, demethylvestitol, and one flavanone naringenin.
