Furanocoumarins from Ruta graveolens possess antifungal activity to several plant pathogenic fungi. 7-Hydroxycoumarin, 4-hydroxycoumarin, and 7-methoxycoumarin were active against Colletotrichum species that cause Anthracnose disease of strawberry.

Enzyme characteristics have been examined for recombinant C4H proteins from several species, including those from P. crispum, P. vulgaris, Ammi majus, H. tuberosus, and Ruta graveolens Similar values toward cinnamate (2 to 10p,A/) are reported, and consistently high substrate specificity (although the values vary between studies). Only 4-coumarate is found as the in vitro product, with no detectable 2- or 3-coumarate production. ...
