General description

4-caffeoylquinic acid (4-CQA) is the derivative of caffeic acid (CA).
It is an ester of caffeic acid and quinic acid.

Application

4-O-Caffeoylquinic acid has been used as a reference compound for the quantification in high performance liquid chromatography-diode array detector (HPLC-DAD).

Biochem/physiol Actions

4-O-Caffeoylquinic acid (4-CQA) is a major active antioxidant marker in mulberry leaf extract. It is an inhibitor of ferroptosis hence, it is recognized as a potent anti-diabetic agent. 4-CQA plays an important role in the upregulation of nuclear factor (erythroid-derived 2)-like 2 (Nrf2) pathway.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
