Polyphenolic glycosides from african proteaceae
The phytochemical investigation of members of the genus Protea afforded a series of polyphenolic compounds (1-5) that were identified by 1D and 2D NMR experiments. Of these, 2-5 are new compounds. Chemical syntheses of 1-3 were performed in order to confirm the structures and to prepare additional material for biological evaluation.
