A lignin composition derived from wood is disclosed. The invention relates to a wood-derived lignin composition comprising:-80 to 90% by weight, based on the total dry matter content of the lignin composition, of an acid-insoluble lignin wherein the lignin has an average molecular weight of 5000 to 15000 Da; -1.5-15% by weight, based on the total dry matter content of the lignin composition, of a carbohydrate; 0.2 to 1.5 wt.% of nitrogen, based on the total dry matter content of the lignin composition; and wherein the weight ratio of oxygen to carbon is at least 0.5. A method of producing a lignin composition derived from wood is also disclosed. 公开了一种源自木材的木质素组合物。所述源自木材的木质素组合物包含：-基于木质素组合物的总干物质含量，80-90重量％的酸不溶性木质素，其中木质素的平均分子量为5000-15000Da；-基于木质素组合物的总干物质含量，1.5-15重量％的碳水化合物；-基于木质素组合物的总干物质含量，0.2-1.5重量％的氮；并且其中，氧与碳的重量比至少为0.5。还公开了一种生产源自木材的木质素组合物的方法。
