Considerable amounts of esterified E-5-hydroxyferulic acid and very small amounts of esterified E-sinapic acid were detected and identified in cell walls of young Zea mays and Hordeum vulgare, in addition to known E-p-coumaric and ferulic acids.Their relative amounts were determined by peak areas using GC.The ratios of E-p-coumaric-5-hydroxyferulic-sinapic-ferulic acid were 440:46:2:100 in corn, and 37:26:3:100 in barley, respectively.
