植物叶多糖的提取和生物活性综述

Review on Extraction and Biological Activity of Polysaccharides from Plant Leave

对各种植物叶多糖的研究有了很多报道,综述了植物叶多糖的提取方法和功能。主要提取方法包括溶剂提取法(水提法、醇提法、酸提法、碱提法)、超声辅助提取法、微波辅助提取法、酶解法;植物叶多糖具有多种生理功能,主要有抗氧化、抗疲劳、降血糖、降血脂、增强免疫活性以及抑菌作用等。

At present, there are many reports about polysaccharides from plant leaf. In this paper, the extraction methods and biological activities of polysaccharides from plant leave are reviewed. The main extraction methods include solvent extraction （water extraction, ethanol extraction, acid extraction, alkali extraction）, ultrasonic assisted extraction, microwave assisted extraction, and enzymatic hydrolysis. Leaf polysaccharides posses various biological activities, mainly including anti-oxidant, anti-fatigue, hypoglycemic, hypolipidemic, immune-stimulating and antimicrobial activities, etc.
