20.500.12556/RUL-146655 Development of extraction methodology for identification of extractive-compounds indexing natural durability of selected wood species This study is concerned with establishing a uniform experimental protocol for the determination of phenolic extractives, which play an essential role in the durability of the wood of selected species included in the field tests. European larch (Larix decidua), Norway spruce (Picea abies), Scots pine (Pinus sylvestris), European oak (Quercus sp.), sweet chestnut (Castanea sativa), and black locust (Robinia pseudoacacia) were included in the study. Extraction yield data were collected for extraction in a Soxhlet apparatus using common polar extraction solvents (ethanol, acetone, methanol, water) and for single static extraction cycles in accelerated solvent extraction (ASE). The suitability of the solvents and the appropriate extraction conditions were evaluated based on the results of gravimetric analysis of hydrophilic extractives, spectrophotometric analysis of total phenols, and chromatographic analysis using high-performance liquid chromatography. Extraction in the ASE system with methanol proved to be a quick and accurate way to prepare samples for chemical analysis of extractives of selected wood species. With the chemical monitoring of targeted phenolic extractives in wood subjected to leaching, we propose a novel protocol suitable also for measuring the effects of weathering on the natural durability of wood in future studies. extraction from wood phenolic extractives natural durability extractive leaching ekstrakcija lesa fenolni ekstraktivi naravna odpornost izpiranje ekstraktivov true false true Angleški jezik Slovenski jezik Članek v reviji 2023-06-05 13:11:27 2023-06-05 13:11:34 2023-12-23 03:54:10 0000-00-00 00:00:00 2023 0 0 Str. 1940-1950 no. 6 Vol. 18 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*8 1748-0280 10.1080/17480272.2023.2207529 151491331 Development_of_extraction_methodology_for_identification_of_extractive-compounds_indexing_natural_durability_of_selected_wood_species.pdf Development_of_extraction_methodology_for_identification_of_extractive-compounds_indexing_natural_durability_of_selected_wood_species.pdf 1 D53B055C030EAC1B690EAD608127F4CD 528b891478bc1a390e060efcaabfdf403ead33498dea2fcdb10d721775cb3288 9ee9fcae-a0a4-11ee-90ad-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=179268 https://www.tandfonline.com/doi/full/10.1080/17480272.2023.2207529 1 69191cc0-0391-11ee-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=169877 Biotehniška fakulteta 0 0 0
