Quebecol is a phenolic chemical compound that has been isolated from Canadian maple syrup. It has the chemical formula C24H26O7 and the systematic name 2,3,3-tri-(3-methoxy-4-hydroxyphenyl)-1-propanol. Analysis of maple sap before it is converted into syrup suggests that this compound is not naturally present in the sap, but instead is formed during extraction or processing.
