Book excerpt: The phenolic and polyphenolic compounds present in date palm, oak, quibracho, banana, and pine wood play a crucial role in the development of natural antioxidants. This study provides structural information on the phenolic compounds isolated from wood obtained from a series of old date palm (OPW), seedling date palm (SPW), oak (OW), quibracho (QW), banana (BW), and pine (PW) and their associated products. The total phenolic content (TPC), total flavonoid content (TFC), tannin content (TC) as well as the antioxidant activity of wood extracts was studied by employing in vitro assays using the free radical scavenger 1,1-diphenyl-2-picrylhydrazyl (DPPH) and iron chelatiom methods. The antioxidant activity and phenolic content of SPW extract, as determined by the DPPH assay, TPC and TC were higher than those of the other wood extracts. Analysis of wood extracts revealed a high amount of phenolics and tannins suggesting a possible role of wood phenolics as a source of natural antioxidants. These studies clearly indicate that the SPW had a significant antioxidant activity. In addition, the antioxidant capacity of soluble- and insoluble-bound phenolics of wood extracts was examined, as well as their bioactivities such as inhibition of oxidation of LDL cholesterol and DNA strands breakage. The results so obtained also confirmed the fact that antioxidant potential and oxidation inhibitory activities were much higher for the SPW compared to other wood extracts. Furthermore, in this study, the date palm wood was used to generate smoke that was subsequently used to prepare smoked salmon, using maple wood as a commercial standard. Prominent volatile compounds released during the smoking process were adsorbed using solid-phase microextraction (SPME) and were then identified by gas chromatography-mass spectrometry (GC-MS). The oxidative stability of the smoked salmon was evaluated in terms of development of thiobarbituric acid reactive substances (TBARS). Regardless of the wood type, volatile compounds were mainly methoxyphenols, with the highest contribution from eugenol, followed by guaiacol and their corresponding derivatives. The phenolic composition of OPW, SPW, OW, QW, BW, and PW were studied using conventional analytical methodologies. In addition, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI- TOF/TOF-MS) and tandem mass spectrometry (MS/MS) analyses were used to examine the structures of various phenolics, tannins, and lignin compounds. The results showed that OPW, SPW, OW, QW were rich in the classes of compounds tested. Both condensed tannin and hydrolyzable tannins were present in high amounts in SPW, OPW, and OW and their phenolics present showed the highest antioxidant values compared to QW, BW, and PW.

Book excerpt: Wood Extractives and their Significance to the Pulp and Paper Industries focuses on the promotion of the study of the biochemistry of wood extractives and to elaborate on the effects these materials may pose to the manufacture of pulp and paper. The publication first elaborates on wood, distribution and formation of polyphenols within the tree, and the simple polyphenolic constituents of plants. Discussions focus on the factors affecting the amounts of polyphenols present in living tissues, glycosidic combination, flavonols, anthocyanins, and leucoanthocyanins, formation of carbohydrates in the tree, types of polyphenols in different tissues of uninjured trees, and variation in structure and properties of wood. The text then examines lignans and condensed and hydrolyzable tannins. The manuscript takes a look at the alicyclic acid precursors of polyphenols, biosynthesis of polyphenols, and tropolones. Topics include tropolones occurring in wood, polymeric polyphenols, synthesis of pre-aromatic compounds, shikimic acid, and quinic acid. The book then ponders on the influence of extractives on the pulping of wood and the influence of extractives on the color of ground wood and newsprint. The publication is a valuable reference for researchers interested in the processes and methodologies involved in the manufacture of pulp and paper.

Available in PDF, EPUB and Kindle. Book excerpt: This book was developed from the proceedings of the 2nd North American Tan nin Conference held in Houghton, Michigan, June, 1991. The objective of this con ference was to bring together people with a common interest in plant polyphenols and to promote interdisciplinary interactions that will lead to a bet ter understand ing of the importance of these substances. Another objective of this conference was to extend the 'tannin family' by making special efforts to encourage participation by scientists outside the United States, obtain more coverage of the hydrolyzable tannins, and further broaden the scope of coverage from the initial concentration on forestry and forest products. Com parison of the contents of this book with 'Chemistry and Significance of Condensed Tannins' that resulted from the proceedings of the 1st North American Tannin Conference shows the degree that these objectives were met. In developing the second conference, care was taken to assure that this book extends rather than duplicates the coverage of the first conference. Therefore, the two books should be taken together to obtain an up to date coverage of the broad area of chemistry and significance of plant polyphenols. Our thanks go to the authors who so kindly contributed chapters and so pa tiently responded to our requests. We thank the Conference Assistance Staff of Michigan Technological University for their help in planning and conducting the conference.
