Phytoalexin produced by aspen in response to infection by Hypoxylon mammatum was isolated and found to be active against ascospore germination of Hypoxylon mammatum and conidial germination of Alternaria sp. Analysis carried out by thin layer chromatography suggests that the active compounds are phenolic glycosides. These compounds gave an inhibition up to 92.5% when tested against the germination of Alternaria spores.
