Usage And Synthesis
Description

Is a phenolic aldehyde crystalline compound with the molecular formula C7H6O3. The compound is released from cork stoppers into wine. Also known as procatechuic aldehyde, protocatechualdehyde can be found in barley, grapevine, green Cavendish, and root of herb S. miltiorrhiza. The compound contains pro-apoptotic and antiproliferative properties against human breast cancer cells as well as colorectal cancer cells by reducing the expression of cyclin D1 and β-catenin.

Description
