Cumarol alcohol

The network structure of lignin, which is made of phenol units, coagulates the cell wall in wood tissue, which is composed of cellulose and hemicellulose. Lignin is currently a waste product because of its complicated structure [1-4], It is produced by an oxidative polymerization of coniferyl alcohol, sinapil alcohol, and cumarol alcohol (Figure 1) catalyzed by metalloenzymes such as laccase and peroxidases. Laccase is a protein whose active center contains four coppers per one subunit [5-20],... 

Figure 8 presents a selected part of a gas chromatogram recorded for the extracts A and B. The extract B consisting of furan derivative contains more oxygen heterocyclic compounds compared to extract A. The excess of 0-heterocycles is responsible for the observed (better) antioxidant activity of extract B (Figure 9). Careful analysis of GC, FT-IR, and NMR results let to identify more than 50 compounds which conld be accounted to the compounds potentially exhibiting antioxidant activity. Some of them are listed in Table 3 which contains names, formulas and information on most typical MS ions observed during the GC-MS identification. In general, most of the identified compounds may be seen as derivatives of the three basic structures (Figure 10) (A) cumarol alcohol, (B) coniferyl alcohol, and (C) synapine alcohol.
