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]

Uses and actions[edit]

It can have a protective antioxidant effect on cultured PC12 cells.[5]

Like various other flavonoids, hyperoside has been found to possess antagonist activity at the κ-opioid receptor.[6]
