Very long chain alkylresorcinols accumulate in the intracuticular wax of rye (Secale cereale L.) leaves near the tissue surface

In the cuticular wax of Secale cereale leaves, homologous series of very long chain 5-alkylresorcinols were identified by GC-MS and comparison with synthetic standard. The phenolics were found in the wax mixtures from the adaxial and the abaxial sides of the leaves. They were restricted to the intracuticular compartment and were lacking from the epicuticular wax layer.
