In this study, polysaccharides from (, abbreviated as ) were obtained by five methods: hot water extraction, microwave extraction, cold water extraction, enzymatic extraction, and ultrasonic extraction. Their structural characteristics, antioxidant properties, and hypolipidemic activities were explored. The results showed that the five polysaccharides all exhibited typical infrared spectral characteristics of polysaccharides. Their monosaccharide compositions were basically the same, all consisting of glucose and mannose, but their surface morphologies differed significantly. The polysaccharide extracted by the enzymatic method had the lowest molecular weight but showed good antioxidant properties. The polysaccharides extracted by ultrasonic and cold water methods showed great potential for hypolipidemic effects. Different extraction methods had impacts on the physicochemical properties, biological activities, and microstructures of polysaccharides. In practical applications, it is necessary to select appropriate extraction methods according to different requirements. The results of this study provide a reference basis for the precise development and utilization of polysaccharides.
在本研究中，通过五种方法获得了[具体名称]的多糖（简称为[缩写名称]）：热水提取法、微波提取法、冷水提取法、酶提取法和超声提取法。对其结构特征、抗氧化性能和降血脂活性进行了探究。结果表明，这五种多糖均呈现出多糖典型的红外光谱特征。它们的单糖组成基本相同，均由葡萄糖和甘露糖组成，但表面形态差异显著。酶法提取的多糖分子量最低，但具有良好的抗氧化性能。超声法和冷水法提取的多糖显示出巨大的降血脂潜力。不同的提取方法对[具体名称]多糖的理化性质、生物活性和微观结构有影响。在实际应用中，有必要根据不同需求选择合适的提取方法。本研究结果为[具体名称]多糖的精准开发利用提供了参考依据。
