植物多酚类物质研究进展

Research progress on plant polyphenols

多酚是高等植物的次级代谢产物,其结构复杂,具有多种功效,如抗氧化作用、抗病毒和抗炎症作用、抑菌作用等。近年来关于天然来源的植物多酚的开发及其在食品中的应用已成为研究热点,主要研究集中在多酚的制备、分离纯化、结构鉴定及生物活性方面。本文在对植物多酚文献分析的基础上,阐述了多酚类物质在提取制备及分离纯化方面的研究现状,重点对多酚类物质含量测定、单酚鉴定及抑菌作用进行了综述,并对植物多酚类物质在今后的研究重点进行了展望,以期为植物多酚类物质在食品工业中的开发利用提供参考和思路。

Polyphenols with complex structures are a class of plant secondary metabolites and have antioxidative, antiviral, anti-inflammatory and antibacterial activities. Polyphenols derived from natural source have already become a research priority in food industry and researches are focused on the preparation, isolation, purification, structure identification and bioactivity of polyphenols. On the basis of literature analysis of plant polyphenols, this article summarized the researches of extraction, separation and purification methods, focusing on the content determination of these compounds, monophenol identification and antimicrobial activities. Moreover, the future development tendencies of plant polyphenols are proposed, so as to provide reference and ideas on application of plant polyphenols in food industry.
