木质素的提取、降解技术及其在制药领域中应用的研究进展

Research Process of Lignin Extraction,Degradation and Application in Pharmaceuticals

木质素是一种天然的芳香生物聚合物,通常由无规聚合的芳香醚单元结构经高度交联而成,是继纤维素与半纤维素以外分布广、产量大的生物质资源,有望成为重要且廉价的芳烃来源,对制药领域而言至关重要。为了更好地将木质素应用于制药领域中,该文综述了木质素的提取方法、降解技术,对木质素及其降解与改性产物在医药领域的应用进行总结归纳,为木质素资源的充分利用与功能化应用提供参考。

Lignin is a kind of natural aromatic biopolymer,which is usually composed of highly cross-linked aromatic ether unit structures through random polymerization.It is a widely distributed and high-yield biomass resource,inferior to cellulose and hemicellulose.It is expected to become an important and inexpensive source of aromatics,which is crucial for the pharmaceutical field.This paper reviews the current extraction methods,degradation technologies of lignin,and summarizes the applications of lignin and its degradation and modification products in the pharmaceutical field,so as to provide some references for the full utilization and functional application of lignin resources.
