麥冬具有生津解渴、潤肺止咳的功效，其主要成分包括甾體皂苷、黃酮類、多糖類等，但是對其多糖類研究相對較少。主要綜述麥冬多糖的化學(xué)組成、分析方法、藥理作用等研究進(jìn)展。麥冬多糖主要有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、3，5-二硝基水楊酸（DNS）比色法、近紅外光譜結(jié)合偏最小二乘回歸法等；麥冬多糖可有效地改善心血管系統(tǒng)疾病，具有耐缺氧、抗炎、抗腫瘤、抗氧化等多種藥理作用。

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.
