Description

General description

3,4-Di-O-caffeoylquinic acid (3,4-COQ) is a component of the medicinal herb Youngia japonica.It has a caffeoyl moiety attached with a hexacyclic quinic acid in its structure.

Application

3,4-Di-O-caffeoylquinic acid has been used as a reference standard:

• to quantify the caffeoylquinic acids of Artemisia frigida Willd. (Fringed sagewort) using high-performance liquid chromatography with diode array detection and electrospray ionization triple quadrupole mass spectrometric detection (HPLC-DAD-ESI-QQQ-MS)
• to quantify the phenolic compounds of Artemisia species using high-performance liquid chromatography with diode array detection (HPLC-DAD) technique
• for metabolic profiling of methanolic leaf extract of A. nallamalayana and to identify the phenolic acids using High-Performance Liquid Chromatography-Ultraviolet (HPLC-UV) analysis

Packaging

1 mg in glass bottle

Biochem/physiol Actions

3,4-Di-O-caffeoylquinic acid, along with 3,5-dicaffeoylquinic acid and luteolin-7-O-glucoside, is a component of the medicinal herb Youngia japonica. It has known antiviral activity and along with 3,5,-dicaffeoylquinic acid, shows activity against respiratory syncyntial virus (RSV). 3,4-COQ elicits antioxidant effects which mediate its neuroprotective effects against in vitro retinal damage. It also exerts cytoprotective effects against oxidative damage in bone marrow-derived mesenchymal stem cells (bmMSCs).
