Abstract Tricin was recently discovered in lignin preparations from wheat (Triticum aestivum) straw and subsequently all monocot samples examined. To provide proof that tricin is involved lignification establish the mechanism by which it incorporates into polymer, 4′-O-β-coupling products of with monolignols (p-coumaryl, coniferyl, sinapyl alcohols) were synthesized along trimer would result its alcohol then coniferyl alcohol. also found to cross couple form tricin-(4′-O-β)-linked dimers...
Abstract Protection groups were introduced during biomass pretreatment to stabilize lignin's α,γ‐diol group its extraction and prevent condensation. Acetaldehyde propionaldehyde stabilized the without any aromatic ring alkylation, which significantly increased final product selectivity. The subsequent hydrogenolysis catalyzed by Pd/C generated lignin monomers at near‐theoretical yields based on Klason (48 % from birch, 20 spruce, 70 high‐syringyl transgenic poplar), with high selectivity a...
Lignin is the most abundant aromatic polymer from natural and renewable lignocellulosic biomass resource. Developing highly efficient catalysts for lignin depolymerization to produce valuable monophenols with high yield selectivity remains a desirable but challenging target in this field. Here, we design synergistic catalyst combining atomically dispersed Mo centers Al Lewis acid sites on MgO substrate (Mo1Al/MgO) of Eucalyptus via β-aryl ether bond cleavage. A near-theoretical monophenol...
Lignocellulose materials are potentially valuable resources for transformation into biofuels and bioproducts. However, their complicated structures make it difficult to fractionate them cellulose, hemicelluloses, lignin, which limits utilization economical conversion value-added products. This study proposes a novel feasible fractionation method based on complete dissolution of bagasse in 1-butyl-3-methylimidazolium chloride ([C(4)mim]Cl) followed by precipitation acetone/water (9:1, v/v)...
Tricin [5,7-dihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-4H-chromen-4-one], a flavone, was recently established as an authentic monomer in grass lignification that likely functions nucleation site. It is linked onto lignin aryl alkyl ether by radical coupling with monolignols or their acylated analogs. However, the level of tricin incorporates into remains unclear. Herein, three characterization methods: acidolysis; thioacidolysis; and derivatization followed reductive cleavage; were applied...
Lignin oxidation offers a potential sustainable pathway to oxygenated aromatic molecules. However, current methods that use real lignin tend have low selectivity and yield is limited by degradation during its extraction. We developed stoichiometric catalytic using 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) as oxidant/catalyst selectively deprotect the acetal oxidize α-OH into ketone. The oxidized was then depolymerized formic acid/sodium formate system produce monomers with 36 mol % (in...
Lignin is a phenolic heteropolymer that deposited in secondary-thickened cell walls, where it provides mechanical strength. A recent structural characterization of walls from monocot species showed the flavone tricin part native lignin polymer, hypothesized to initiate chains. In this study, we investigated consequences altered levels on structure and wall recalcitrance by profiling, nuclear magnetic resonance, saccharification assays naturally silenced maize (Zea mays) C2-Idf (inhibitor...
Lignin is an abundant aromatic plant cell wall polymer consisting of phenylpropanoid units in which the rings display various degrees methoxylation. Tricin [5,7-dihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-4H-chromen-4-one], a flavone, was recently established as true monomer grass lignins. To elucidate incorporation pathways tricin into lignin, metabolites maize (Zea mays) were extracted from lignifying tissues and profiled using developed 'candidate substrate product pair' algorithm applied...
Lignin is the most abundant aromatic polymer in nature and as such an attractive source of molecules. Efficient lignin utilization will also likely play a key role economic success sustainability biomass valorization schemes. However, traditional strategies for isolation depolymerization suffer from repolymerization issues, which result low yield molecular weight fragments. This review summarizes recent progress methods that are able to limit condensation facilitate high production monomers...

Abstract Lignin is a phenylpropanoid polymer produced in the secondary cell walls of vascular plants. Although most eudicot and gymnosperm species generate lignins solely via polymerization p -hydroxycinnamyl alcohols (monolignols), grasses additionally use flavone, tricin, as natural lignin monomer to tricin-incorporated polymers walls. We previously found that disruption rice 5-HYDROXYCONIFERALDEHYDE O -METHYLTRANSFERASE ( OsCAldOMT1 ) reduced extractable tricin-type metabolites vegetative...
