Hyperoside has been isolated fromDrosera rotundifolia, from the LamiaceaeStachys sp. andPrunella vulgaris, fromRumex acetosella,Cuscuta chinensis seeds, fromSt John's wort and fromCamptotheca acuminata.[1] It is one of the phenolic compounds in the invasive plantCarpobrotus edulis and contributes to the antibacterial[2] properties of the plant.
