“…Walnut heartwood extractives have also mainly composed of ellagitannins. (Fukuda et al 2003;Yalcin et al 2018) Deionised water and pure ethanol (Sigma-Aldrich) used for sorption experiments were outgassed before use. The binary mixtures of ethanol and water were prepared with 1:2 and 2:1 ratios, i.e.…”

Water is a universal solvent and swelling agent that is widely used in wood industry in association with organic solvents and salts, whether for the fractionation of biomass and the production of bio-based synthons for the chemical industry, the application of sizing agents and painting for the paper industry, or the incorporation of preservatives to enhance wood durability for the timber industry. The relevance of solvents and technical treatments used for wood-based products requires a proper identification of the specific role of each solvent on wood biopolymers to better understand and predict their influence on wood properties. In particular, wood impregnated with aqueous solutions of organic solvents have shown to give rise to greater swelling than that observed in pure water, described as “hyperswelling”. To understand this phenomenon, the first step is to examine the existing interactions between wood microstructure and the different solvents present in these mixtures. This study is an attempt to bring to light the sorption behaviour of four different hardwoods in water–ethanol vapour mixtures containing increasing molar fractions of ethanol from 0 to 100%. Contrasted sorption behaviour in pure solvents were observed according to wood species having different biochemical composition. This behaviour highlights the different affinities of ethanol and water for the macromolecules present in the wood microstructure. With mixed solvents, peculiar effects were confirmed in sorption behaviour of woods with lower mixed solvent uptake at high partial pressures compared to pure solvents. It is also shown that part of the sorbed ethanol molecules remains chemisorbed in the wood structures at the end of the desorption process.

Wood Waste from Fruit Trees: Biomolecules and Their Applications in Agri-Food Industry

In the European Union (EU), a total of 11,301,345 hectares are dedicated to the cultivation of fruit trees, mainly olive orchards, grapevines, nut trees (almond, walnut, chestnut, hazelnut, and pistachio), apple and pear trees, stone fruit trees (peach, nectarine, apricot, cherry, and plum), and citrus fruit trees (orange, clementine, satsuma, mandarin, lemon, grapefruit, and pomelo). Pruning these trees, together with plantation removal to a lesser extent, produces a huge amount of wood waste. A theoretical calculation of the wood waste in the European Union estimates approximately 2 and 25 million tons from wood plantation removal and pruning, respectively, per year. This wood waste is usually destroyed by in-field burning or crushing into the soil, which result in no direct economic benefits. However, wood from tree pruning, which is enriched in high added-value molecules, offers a wide spectrum of possibilities for its valorization. This review focuses on the contribution of wood waste to both sustainability and the circular economy, considering its use not only as biomass but also as a potential source of bioactive compounds. The main bioactive compounds found in wood are polyphenols, terpenes, polysaccharides, organic compounds, fatty acids, and alkaloids. Polyphenols are the most ubiquitous compounds in wood. Large amounts of hydroxytyrosol (up to 25 g/kg dw), resveratrol (up to 66 g/kg dw), protocatechuic acid (up to 16.4 g/kg), and proanthocyanins (8.5 g/kg dw) have been found in the wood from olive trees, grapevines, almond trees and plum trees, respectively. The bioactivity of these compounds has been demonstrated at lower concentrations, mainly in vitro studies. Bioactive compounds present antioxidant, antimicrobial, antifungal, biostimulant, anti-inflammatory, cardioprotective, and anticarcinogenic properties, among others. Therefore, wood extracts might have several applications in agriculture, medicine, and the food, pharmaceutical, nutraceutical, and cosmetics industries. For example, olive tree wood extract reduced thrombin-induced platelet aggregation in vitro; grapevine tree wood extract acts a preservative in wine, replacing SO2; chestnut tree wood extract has antifungal properties on postharvest pathogens in vitro; and stone tree wood extracts are used for aging both wines and brandies. Moreover, the use of wood waste contributes to the move towards both a more sustainable development and a circular economy.

“…Ellagic acid has several pharmacology activities. As an anti-cancer, anti-inflammatory, anti-bacterial and fungal, anti-diabetic, hepatoprotective and scavenging the free radical (Mogana & Wiart, 2011;Shakeri et al, 2018;Yalcin et al, 2018;García-Niño & Zazueta, 2015). This compound is a product of hydrolysis of tannin as an ellagitannin.…”

“…Plants produce it from the hydrolysis of tannins such as ellagitannin and geranin for use as protectors from microbiological infections, heavy metal poisoning, predation by insects, and pests (Aguilera-Carbo et al, 2008;Hamada et al, 2019;Yalcin et al, 2018;Shakeri et al, 2018;Ríos et al, 2018). Ellagic acid has the ability to reducing the oxidative stress in cells and has beneficial a chemopreventive substance, anti-proliferative, anti-viral, anti-bacterial and an antioxidant and had reported in recent studies (Yalcin et al, 2018;Devipriya et al, 2007).…”

Hydrargyrum (familiar as mercury) is a persistent transition metal element. They are known as bio-accumulative properties that are dangerous to the environment and has serious damaging effects on biota, including genetic changes or mutagenesis. Moreover, it can accumulate indirectly in the human body due to the consumption of products that have contaminated. Whereas, ellagic acid has reported as one of 13 flavonoid compounds that have potential as an anti-mutagen and anti-cancer in the walnuts seeds. This study was aimed to ensure the potential extent of ellagic acid extracts in walnut seeds to reducing and repairing the genotoxicity effects of mercury. Therefore, using the experimental method, this study was divided into several test treatments. Two controls treatment as a comparison of the presence of micronucleus with group tests that given a 20 ppm mercury dosage. Then continued with the addition of walnut seed extract with various dosage (10, 15, and 20 ppm) by oral injection continuously for two weeks as a recovery process to reducing and repairing the genotoxicity effect of mercury. The significant results showed that there are differences between pre and post-treatment. It indicated that the extract has the potential for improving and reducing the genotoxicity effect of mercury. The data were evaluated and obtained the total micronucleus from the smear of peripheral blood of mice by comparing the total micronucleus before and after giving of walnut extract.
