Abstract: We extracted the lignin by kraft and ethanol method, with the residues of Acanthopanax root and stem as raw materials. We obtained two kinds of lignin, and measured the contents of active groups and composition including phenolic hydroxyl, carboxyl, hydroxyl and carbonyl. Our study will provide the theoretical and experimental basis for high-value resources applications of organic lignin.

Key words: lignin, kraft lignin, ethanol, groups
