说明

3,4-Di-O-caffeoylquinic acid 是药草 Youngia japonica 的一种成分。
3,4-COQ 在其结构中具有与六环奎尼酸相连的咖啡酰部分。

3,4-COQ 引发抗氧化作用，介导其对体外视网膜损伤的神经保护作用。 它还对骨髓来源的间充质干细胞 (bmMSCs) 的氧化损伤发挥细胞保护作用。

3,4-二-O-咖啡酰奎尼酸以及 3,5-二咖啡酰奎尼酸和木犀草素-7-O-葡萄糖苷是药草 Youngia japonica 的成分。 它具有已知的抗病毒活性，并且与 3,5,-二咖啡酰奎宁酸一起，显示出抗呼吸道合胞病毒 (RSV) 的活性。

一般描述

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

应用

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

生化/生理作用

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).
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).
