“… 23 Nevertheless lignans have been poorly studied in grapes and wine. 24 A study by Balik et al 25 evaluated the addition of lignan extracts from spruce knot chips stripped of resin to red and white wines. The most relevant results showed that the intensity of the woody aroma and also the astringency and bitterness of all of the wine samples increased with the quantity of lignan extracts added, and this had good consumer acceptability.…”

The recovery of raw materials offers an opportunity for applying the principles of circular bioeconomy. The phenolic composition of three underused wine byproducts (skin, seed, and bunch stem) was analyzed through UHPLC-QqQ-MS/MS to evaluate the intercultivar variability comparing red and white grape cultivars from La Rioja (Spain) and the influence of the winemaking, comparing conventional fermentation and carbonic maceration. We observed that the red skin, especially from Graciano, is rich in anthocyanins, whereas the white skin contains mainly phenolic acids, flavonols, and flavan-3-ols, with Maturana Blanca being the richest variety. Seeds are rich in flavan-3-ols and lignans with Maturana Blanca and Viura, respectively, the richest cultivars. Stems contain high amounts of flavan-3-ols, lignans, and stilbenes, with the red cultivars of Garnacha and Tempranillo being the richest samples. Carbonic maceration has a negative effect on the phenolic amount compared to conventional fermentation. In synthesis, we observed that each type of byproduct from red or white grape cultivars has a particular phenolic composition that can result in obtaining different ingredients with particular phenolic composition for target applications.

“…Lignans are an important family of bioactive compounds with antifungal, antibacterial and insecticidal effects, which are used by conifers as a chemical defense; moreover, they have also shown pharmacological properties as anticarcinogens, and as a food supplement because of their beneficial effects on human health [18][19][20]. For instance, extracts of lignan-rich Picea abies knots are added to the winemaking process to improve its properties enhancing its quality [21,22]. The lignans secoisolariciresinol, eudesmin, lariciresinol and pinoresinol have already been reported in the heartwood of native Chilean species such as A. araucana, Fitzroya cupressoides, and Austrocedrus chilensis [18,23,24].…”

Araucaria araucana is a native conifer of Chile commonly called Araucaria. The knots of Araucaria are extremely hard wood and highly rot-resistant, they can be found in the forest decades after that the tree has dead and decomposed. Here we report the phytochemical characterization of different parts of the Araucaria as stemwood, branch and knots, founding a remarkable difference in the content of extractables in these parts, as well as the lignan composition, which is higher in knots than in branches or stemwood. Eudesmin was isolated and crystallized from organic extract of knots, its structure was determinate by NMR; moreover, secoisolariciresinol, lariciresinol and matairesinol were identified by GCMS and HPLC in contrast to standards, and quantified in stemwood, branch and knots. The results showed that secoisolariciresinol is the main lignan with 45.77 mg g-1 , followed by eudesmin with 22.68 mg g-1 , lariciresinol 4.57 mg g-1 and matairesinol with 1.19 mg g-1. The antioxidant activity in terms of DPPH assay showed that knotwood extract displays the higher activity, meanwhile that eudesmin did not displays activity in DPPH assay. The cytotoxic activity against SHSY5Y neuroblastoma and P3X myeloma cell lines, revelated a moderate activity of extracts, while eudesmin did not showed activity.

“…Moreover, wood compounds may increase seedling resilience via the activation of plant's defence metabolism (Mandal et al 2010). For example, lignans (a group of polyphenolics) exert strong antioxidant activity (Harmatha and Dinan 2003;Korkina 2007;Balík et al 2017). Lignans are thus potentially very effective inducers of plant defence.…”

Variation in the chemical quality of woody supplements for nursery growing media affects growth of tree seedlings

Tree seedlings are produced in tree nurseries. However, nursery-grown seedlings often exhibit poor performance after outplanting due to the lack of adaptation to harsh natural conditions. These nursery-grown seedlings do not necessarily possess well-developed ectomycorrhizal symbionts, which help to obtain nutrients and increase resilience in exchange for seedling photoassimilated carbon. To improve the quality of the seedlings in natural conditions, we sowed spruce seeds on growing media with the addition of wood chips, i.e. stemwood chips or polyphenol- and resin acid-rich knotwood chips. Wood chips were chosen because they are common forest side-streams, and their compounds have shown a potential to improve mycorrhization and seedling fitness. Wood chips initially decreased the growth of seedlings. However, this effect levelled off with time and depended on the quality of the wood. Wood chips had no effect on mycorrhization. Further testing of the wood material showed that wood chips seemed to decrease seedling growth via nitrogen (N) immobilisation rather than a direct toxic effect. The phenomenon of N immobilisation on wood chips could be explored further to develop a slow-release N source, aptly reflecting N availability in natural conditions. Slow-release N source based on wood chips could be beneficial both to increase survival in natural conditions and for environment protection.
