Abstract: Sweet potato leaves are the aboveground parts of sweet potato, which can be harvested several times a year, and their yield is equal to that of sweet potato roots. Sweet potato leaves are rich in polyphenols, including phenolic acids and flavonoids. These compounds have been reported to possess many healthy benefits, such as antioxidant, antihyperglycemic, antimicrobial, anti-inflammatory, anti-tumor hepatoprotective, immunomodulatory, etc. Recently, more and more researchers pay attention to the antihyperglycemic activity of sweet potato leaf polyphenols. This article summarized the research progress in extraction, separation and purification of polyphenols from sweet potato leaves, and the individual phenolic composition and antihyperglycemic activity of sweet potato leaf polyphenols. The aim of this article is to provide a theoretical reference for the development and successful application of sweet potato leaf polyphenols in food and healthcare industries, and further enhance sustainable development of sweet potato leaf processing industry in China.

Key words: sweet potato leaves, polyphenols, extraction and purification, composition, antihyperglycemic activity

摘要: 甘薯茎叶为甘薯地上蔓生部分,一年能多次采收,与甘薯块茎产量相当。甘薯茎叶中的多酚类物质含量丰富,主要为酚酸类和黄酮类物质,具有抗氧化、降血糖、抗菌消炎、抗肿瘤、保护肝脏和免疫调节等作用,且甘薯茎叶多酚类物质的降血糖作用已成为天然产物活性研究领域的热点之一。本文综述了甘薯茎叶多酚类物质的提取和分离纯化方法、酚酸类和黄酮类物质的组分构成及体外、体内降血糖活性作用,并展望了甘薯茎叶多酚类物质降血糖活性的研究方向,旨在为甘薯茎叶多酚类物质在食品和医疗保健领域的开发应用提供理论参考,提高甘薯茎叶多酚类物质的有效开发利用率,进一步促进我国甘薯茎叶加工业的可持续发展。
