Hyperoside is a chemical compound. It is the 3-O-galactoside of quercetin.
Natural occurrences[edit]
Hyperoside has been isolated from Drosera rotundifolia, from the Lamiaceae Stachys sp. and Prunella vulgaris, from Rumex acetosella, Cuscuta chinensis seeds, from St John's wort and from Camptotheca acuminata.[1] It is one of the phenolic compounds in the invasive plant Carpobrotus edulis and contributes to the antibacterial[2] properties of the plant.
In Rheum nobile and R. rhaponticum, it serves as a UV blocker found in the bracts.
It is also found in Geranium niveum[3] and Taxillus kaempferi.[4]
