New dienol phytoalexins isolated from Arachis hypogaea leaves infected with Puccinia arachidis speg.
Deux phytoalexines dienoliques, l' ester methylique 9-hydroxy 10, 12 octadecadienoique et l' ester methylique 13-hydroxy 9, 11 octadecadienoique, ont ete isolees a partir de feuilles d' arachide infestees par Puccinia arachidis. L' extraction, la purification, la caracterisation et l' activite anti-fongique de ces composes sont presentees, et leur role eventuel dans la protection des hotes contre l' infestation pathogenique est discute.
