20.500.12556/RUL-143676 Impact of steam-sterilization and oven drying on the thermal stability of phenolic extractives from pine and black locust wood The main goal of the investigation was to measure and estimate the thermal stability of pinosylvin, pinosylvin monomethyl ether, robinetin, and dihydrorobinetin, i.e., characteristic compounds of wood of Scots pine and black locust, respectively. The pure compounds were analyzed with chromatography before and after they were steam-sterilized and oven-dried. Detailed thermogravimetric analysis was followed to check the thermal decomposition of the stilbenes and flavonoids of wood. The tested phenolic compounds were susceptible to thermal degradation. After the steam-sterilization and oven drying, the amount of investigated phenolic extractives decreased by more than a half. The thermogravimetric analysis showed that stilbenes decompose differently than flavonoids, which can be attributed to the different chemical structures. Twenty minutes of steam sterilization followed by 24 h of oven drying decreased the amount of phenolic compounds in the vials; however, after the applied thermal treatments, the stilbenes and robinetins stayed available in such quantities that they can still provide sufficient bioactivity. thermal stability phenolic compounds autoclaving oven drying Scots pine black locust HPLC TGA wood les parna sterilizacija sušenje v sušilniku termična stabilnost HPLC TGA rdeči bor robinija true false true Angleški jezik Slovenski jezik Članek v reviji 2023-01-06 16:27:47 2023-01-06 16:27:50 2023-07-17 13:24:11 0000-00-00 00:00:00 2022 0 0 Str. 467-477 no. 6 Vol. 42 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*8 1532-2319 10.1080/02773813.2022.2123520 123186947 Impact_of_steam_sterilization_and_oven_drying_on_the_thermal_stability_of.pdf Impact_of_steam_sterilization_and_oven_drying_on_the_thermal_stability_of.pdf 1 58670DF3DD4EC9FA7CEE464138458D1D 423d3c2277d11bc6c61e36af364cfd5c65e491ffa83571645a792585eafa115b 942c8137-8dd6-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=165533 https://www.tandfonline.com/doi/full/10.1080/02773813.2022.2123520 1 76fcfcd9-8dd6-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=165532 Biotehniška fakulteta Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
