title: Cannabiorci- and 8-chlorocannabiorcichromenic acid as fungal antagonists from Cylindrocarpon olidum.
abstract: Cannabiorcichromenic acid and 8-chlorocannabiorcichromenic acid [8-chloro-5-hydroxy-2,7-dimethyl-2-(4-methyl-3-pentenyl)-2H-1-benzopyran -6- carboxylic acid] were identified as active components in cultures of Cylindrocarpon olidum which antagonized various other fungi. Experiments performed with the purified acids confirmed the antifungal activity; in addition, they revealed that the acids had antibiotic properties towards gram-positive bacteria and were toxic to nematodes.
