Vsebnost ekstraktivov v skorji in lesu robinije (Robinia pseudoacacia L.) = Content of extractives in bark and wood of Black locust (Robinia pseudoacacia L.)Vek, Viljem ...Raziskali smo vsebnost in sestavo ekstraktivov v lesnih tkivih in skorji robinije (Robinia pseudoacacia L.). Vzorce njenega lesa in skorje smo ekstrahirali v aparatu Soxhlet z acetonom. Acetonske ... ekstrakte smo preiskali gravimetrično in s tem izmerili vsebnost skupnih hidrofilnih ekstraktivov. Z UV-Vis spektrofotometrom smo kolorimetrično izmerili vsebnost skupnih fenolov. Ekstrakte lesa in skorje robinije smo nato detajlno preiskali s sistemom za tekočinsko kromatografijo visoke ločljivosti (HPLC). S to tehniko smo v ekstraktih identificirali in kvantitativno ovrednotili dihidrorobinetin. Največje vsebnosti skupnih hidrofilnih ekstraktivov, skupnih fenolov in dihidrorobinetina smo izmerili v vzorcih jedrovine. Značilno manj ekstraktivov je bilo v vzorcih beljave in skorje. Aksialne variabilnosti v vsebnosti topnih komponent za les in skorjo robinije nismo dognali. Ugotovili smo, da je jedrovina robinije bogat vir fenolnih ekstraktivov.Source: Acta Silvae et Ligni. - ISSN 2335-3112 ([Št.] 119, 2019, str. 13-25)Type of material - article, component partPublish date - 2019Language - slovenianCOBISS.SI-ID - 5472934
