quercetin-3-O-sophoroside

Quercetin 3-O-sophoroside is a flavonoid glycoside that has been found in B. napus (rapeseed) and has antioxidant activity. Quercetin 3-O-sophoroside has a relative antioxidant capacity of 1.45 compared to Trolox in an ABTS assay. It also inhibits lipid peroxidation in a cell-free assay using phospholipid liposomes with an IC₅₀ value of 9.2 μM.

White crystalline powder, soluble in organic solvents such as methanol, ethanol, and DMSO, derived from A. venetum L.

Quercetin-3-O-Sophoroside is an Ipomoea aquatica composite compound which displays antioxidant activity and is used in food chemistry. It is a flavonoid used in traditional Chinese medicine as well.

ChEBI: A quercetin O-glucoside that is quercetin attached to a beta-D-sophorosyl residue at position 3 via a glycosidic linkage.
