麦冬具有生津解渴、润肺止咳的功效，其主要成分包括甾体皂苷、黄酮类、多糖类等，但是对其多糖类研究相对较少。主要综述麦冬多糖的化学组成、分析方法、药理作用等研究进展。麦冬多糖主要有MDG-1、Md-1、Md-2、OJP-1等；目前主要采用的分析方法有蒽酮-硫酸法、苯酚-硫酸法、3，5-二硝基水杨酸（DNS）比色法、近红外光谱结合偏最小二乘回归法等；麦冬多糖可有效地改善心血管系统疾病，具有耐缺氧、抗炎、抗肿瘤、抗氧化等多种药理作用。

The main ingredients of Ophiopogon japonicas include steroidal saponins, flavonoids, polysaccharides, and so on, but the research on polysaccharides is relatively less. This particle will mainly review the chemical composition, analytical methods, and pharmacological effects of Ophiopogon polysaccharides. The Ophiopogon polysaccharides contain a variety of substances, such as MDG-1, Md-1, Md-2, OJP-1, etc; The main analysis methods were sulfuric acid method, phenol-sulfuric acid method, 3,5-dinitrosalicylic acid (DNS) colorimetric method, and near-infrared spectroscopy combined with partial least squares regression method. Ophiopogon polysaccharides can effectively improve the cardiovascular system diseases, with antihypoxia, anti-inflammatory, antitumor, anti-oxidation, and other pharmacological effects.
