鱼腥草多糖的研究进展

鱼腥草有“中药抗生素”之称，是我国重要的药食两用资源；鱼腥草多糖（Houttuynia cordata polysaccharide，HCP）为其主要的活性成分之一，已有研究表明HCP具有良好的抑菌、抗病毒、抗炎、免疫调节、肠道保护、抗氧化等多种作用。近年来，HCP的结构特征和生物活性功能研究已经成为科研工作者关注的焦点。本文主要总结了HCP的提取方法、结构特征、生物活性以及构效关系的研究进展，不仅有利于鱼腥草及其多糖资源的应用开发，还可为进一步深入探究HCP的构效关系提供参考。

Research Progress of Houttuynia cordata Polysaccharide

Houttuynia cordata Thunb was commonly known as"antibiotic of traditional Chinese medicine",which is an important medicinal/dietary resource in China.Houttuynia cordata polysaccharide(HCP)is one of its main active components,and many researches have shown that HCP can exert potent antibacterial,antiviral,anti-inflammatory,immune regulation,intestinal protection,antioxidant,and other bioactivities.Recently,its structural characteristics and biological activity have become the focus of researchers.In this work,the extraction methods,structural characteristics,bioactivity,and structure-activity relationship of HCP are highlighted.Taken together,the article is not only beneficial to promote the application and development of Houttuynia cordata Thunb and polysaccharide resources,but also provides reference for further investigation involved in the structure-activity relationship of HCP.
