Description
We have examined the constituents of bracken fern, Pteridium aquilinum var. latiusculum and performed fractionation of the boiling water extracts by means of the assay based on carcinogenicity to rats. From the fraction exhibiting carcinogenicity, we have isolated an unstable norsesquiterpene glucoside of illudane type named ptaquiloside (1). The planar structure of (1) has been established on the basis of spectral and chemical means. The carcinogenicity of (1) to rats is currently under investigation.
