Lignin smrekovega lesa

Vesna Tišler (Author), Miha Humar (Author)

Abstract

Smrekov lignin je zapleten naravni klobčičasti polimer, ki še do danes ni v celoti raziskan. Temu je vzrok velika heterogenost, ki izhaja iz starosti drevesa, rastnih pogojev, mesta odvzema vzorca, letnega časa, načina izoliranja, itd. Smrekov lignin je z esterskimi, eterskimi in glikozidnimi vezmi vezan predvsem na lesne polioze, zato je popolna izolacija lignina iz lesa ovirana oziroma, praktično onemogočena. Ena izmed možnosti proučevanja lignina je tudi proučevanje biosinteze lignina, ki omogoča dodatno razumevanje strukture lignina, kar je pri drugih destruktivnih metodah oteženo

Secondary abstract:	Spruce lignin is complicated natural three-dimensional polymer and it's structure is not known completely till today. The reason for this is it's great heterogenity, which is influenced by various factors: age of tree, growing conditions, place of sample, year season, way of isolation, etc. Spruce lignin is with ester, eter and glicosides bonds tied mainly on wood polioses and for that reason the totaly isolation of lignin from wood is impediment respectively practically imossible. One way of researching lignin is researching it's biosynthesis, which enables further knowing of lignin structure, what is more difficult with other destructive methods
