桑树(拉丁名“MorusalbaL.”)是桑科的多年生落叶树,广泛分布在世界各地。在中国,桑树主要分布在南方和长江流域。它的叶子一年可以收获3-6次,具有很大的资源优势。桑叶被视为药食同源的中药(TCM)。多糖,作为其主要活性成分,有各种影响,如抗氧化剂,低血糖,保肝,和免疫调节。本文综述了国内外在提取方面的研究进展,净化,结构表征,近十年来桑叶多糖的结构-功能关系,希望为桑叶多糖的后续开发和市场应用提供参考。
Mulberry (Latin name \"Morus alba L.\") is a perennial deciduous tree in the family of Moraceae, widely distributed around the world. In China, mulberry is mainly distributed in the south and the Yangtze River basin. Its leaves can be harvested 3-6 times a year, which has a great resource advantage. Mulberry leaves are regarded as the homology of medicine and food traditional Chinese medicine (TCM). Polysaccharides, as its main active ingredients, have various effects, such as antioxidant, hypoglycemic, hepatoprotective, and immunomodulatory. This review summarizes the research progress in the extraction, purification, structural characterization, and structure-function relationship of polysaccharides from mulberry leaves in the last decade, hoping to provide a reference for the subsequent development and market application of polysaccharides from mulberry leaves.
