Six new antimicrobial and nematicidal bisabolanes from the basidiomycete Cheimonophyllum candidissimum

Abstract The structures of six new bisabolane sesquiterpenes, cheimonophyllon A - E ( 1 - 5 ) and cheimonophyllal ( 6 ), have been determined by spectroscopic methods. The compounds are fungal metabolites isolated from cultures of the Basidiomycete Cheimonophyllum candidissium , and possess antibiotic and nematicidal activities.
