Abstract:
Two antifungal terpenoids, 6-isopropyltropolone β-glucoside and 5-(3-hydroxy-3-methyl-trans-1-butenyl)-6-isopropyl-tropolone β-glucoside, named by us cupressotropolone A and B, respectively, were isolated from the bark of Italian cypress, in response to infection by the fungus Diplodia pinea f. sp. cupressi. These tropolone glucosides inhibited in vitro germination of spores of Diplodia pinea f. sp. cupressi, Seiridium cardinale, Alternaria alternata and Verticillium dahliae. © 1995.
