title: Chemical investigation of the metabolites from the Canadian tuckahoe, Polyporus tuberaster.
abstract: The metabolites of the Canadian tuckahoe, the sclerotium of Polyporus tuberaster, have been investigated. The ten-membered lactone tuckolide [1] was isolated, and its structure was determined by spectroscopic methods and confirmed by X-ray crystallography. Ergosterol, ergosterol peroxide, and several unidentified ergosterol derivatives were also obtained, along with an unidentified disaccharide.
