HPLC profiles of phenolic extracts from lignin (commercial) (E) and wheat bran (F). The peak at retention time (RT) 23.19 was identified as acetosyringone. Different compounds of lignin monomer pathways were used as standards, i.e. acetosyringone, RT 23.19 (A); caffeic acid, RT12.142 (B); 4-hydroxybenzylalcohol RT 37.642 (C) and cinnamic acid RT 26.350 (D).
