Whole seed coat cell wall preparations from mature seeds of J. curcas
(A), V. fordii
(B), A. moluccana
(C), and C. hassleriana
(D). Aromatic and aliphatic subregions are displayed. Volume integrals are given for the lignin aromatic units and side-chain structures that are color-coded to match their assignments in the spectrum.
