Application

Quercetin 3-β-D-glucoside has been used:
  • as a dietary flavonoid supplement to check its binding capacity with human small ubiquitin-related modifier 1 (SUMO1) protein using surface plasmon resonance (SPR)
  • as an inhibitor for Escherichia coli adenosine triphosphate (ATP) synthase
  • as an anti-aggregation agent to test its activity against β-amyloid, green fluorescent protein (GFP), and chymotrypsinogen proteins

Biochem/physiol Actions

Quercetin 3-β-D-glucoside possesses strong antioxidant and anti-inflammatory activities. Being a potent oxygen-radical scavenger, it is a neuroprotective agent that improves Alzheimer′s disease (AD) condition in mice models. It has shown antiproliferative activity against colon, lung, and hepatocellular cell lines and MCF-7 human breast cancer cells in combination with apple extracts.

General description

Quercetin 3-β-D-glucoside (Q3G), also known as isoquercitrin, is one of the major glycosidic forms of quercetin. It is a mono-glucoside, first isolated from the seed pods of Cercis canadensis L., it is also found in various plants, vegetables, and fruits. Q3G has the basic chemical structure of a flavonoid, with a glucose molecule attached to the C-3 of quercetin.
