With the bioactivities of antioxidant, anti-bacteria, anti-inflammation, immune regulation, antitumor and anti-coagulation, plant and microbial polysaccharides have been widely used in foods, medicine and cosmetics. However, how structure features affect the physicochemical property and bioactivity of plant and microbial polysaccharides is still unclear. Ultrasonic degradation usually degrades or modifies plant and microbial polysaccharides with different physicochemical properties and bioactivities by affecting their chemical or spatial structures via mechanical bond breaking and cavitation effects. Therefore, ultrasonic degradation might be an effective strategy for producing bioactive plant and microbial polysaccharides and analyzing their structure-function relationship. Present review summarized the influence of ultrasonic degradation on structural feature, physicochemical property and bioactivity of plant and microbial polysaccharides. Moreover, further problems need to be paid attention to during the application of ultrasonication for plant and microbial polysaccharides degradation are also recommended. Overall, present review will provide an efficient method for producing enhanced bioactive plant and microbial polysaccharides and analyzing their structure-activity relationship based on ultrasonic degradation.
植物和微生物多糖具有抗氧化、抗菌、抗炎、免疫调节、抗肿瘤和抗凝血等生物活性，已广泛应用于食品、医药和化妆品领域。然而，结构特征如何影响植物和微生物多糖的物理化学性质和生物活性仍不清楚。超声降解通常通过机械断键和空化效应影响植物和微生物多糖的化学或空间结构，从而降解或修饰具有不同物理化学性质和生物活性的多糖。因此，超声降解可能是生产生物活性植物和微生物多糖并分析其结构-功能关系的有效策略。本综述总结了超声降解对植物和微生物多糖结构特征、物理化学性质和生物活性的影响。此外，还提出了在应用超声处理降解植物和微生物多糖过程中需要进一步关注的问题。总体而言，本综述将为基于超声降解生产增强生物活性的植物和微生物多糖并分析其构效关系提供一种有效方法。
