摘要：

A solvent system is described for the complete separation of ferulic acid, p-coumaric acid and vanillin on silica gel 60A K6F thin-layer plates. A spray reagent which distinguishes between these substances on a colour basis is also described. After separating the alkali-labile phenolic monomers in grass cell wall material on thin-layer plates, these substances were quantitatively eluted and assayed by means of a spectrophotometric procedure.
