ISOLATION AND STRUCTURES OF TWO NEW p-HYDROXYSTYRENE GLYCOSIDES, PTELATOSIDE-A AND PTELATOSIDE-B FROM BRACKEN, PTERIDIUM AQUILINUM VAR. LATIUSCULUM, AND SYNTHESIS OF PTELATOSIDE-A

Article abstract of DOI:10.1246/cl.1984.397

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.
