Abstract
A new method for qualitative determination of 1-O-trans-p-coumaroylgly cerol, using reversed-phase HPLC in combination with a coulometric ele ctrode array detector, was developed. The occurrence of this ester in maize, sorghum and beer brewed with those compounds was confirmed. The results were verified by liquid chromatography-mass spectrometry. The HPLC method can be used to prove an addition of maize or sorghum to m ash in the brewing process.
