• Cellulose
• C-13 isotopic tracer
• CP/MAS NMR
• Lignin-carbohydrate complexes

In order to further understand the association between cellulose and lignin in gymnosperm plant, carbohydrate part of the lignin-carbohydrate complexes was analyzed. Cellulose precursor i.e. (6-C-13)uridine diphoshphate glucose, was synthesized, and injected into a living ginkgo tree with lignin inhibitor AOPP and exogenous lignin precursor. The results from the determination of C-13 abundance indicate that the deposition of cellulose in the cell wall is very fast and effective in the primary wall. The analysis of high resolution solid nuclear magnetic C-13 NMR spectra confirms that the bonds between C-6 position of glucose units in cellulose and a-carbons of lignin side chain are benzyl ether linkage.
