Abstract
Two new p-hydroxystyrene glycosides, ptelatoside-A and ptelatoside-B were isolated from the carcinogenic fraction of aqueous extracts of bracken, Pteridium aquilinum var. latiusculum, and their structures were established to be p-β-primeverosyloxystyrene and p-β- neohesperidosyloxystyrene, respectively by chemical and spectral means. A synthesis of ptelatoside-A was achieved.
