Auricularia auricula polysaccharides (耳廓多糖（AAP) have been widely studied in the field of medicine and healthcare because of their unique structure and physiological activity. Many species of Auricularia auricula polysaccharides have been extracted, isolated, and purified by different methods, and their structures have been analyzed. Auricularia auricula polysaccharides have been proven to have beneficial effects on the human body, including slowing the aging process, controlling the intestinal system, and treating cardiovascular disorders. In this paper, the extraction, isolation, and purification of ）因其独特的结构和生理活性而在医学和保健领域得到了广泛的研究。通过不同的方法提取、分离和纯化了许多种类的耳木多糖，并对其结构进行了分析。耳廓多糖已被证明对人体有益，包括减缓衰老过程、控制肠道系统和治疗心血管疾病。本文从耳廓中提取、分离和纯化AAP from Auricularia auricula, as well as research in the field of medicine and healthcare, have pointed to the shortcomings and limitations of these methods. We also suggest future research directions for Auricularia auricula polysaccharides，以及医学和保健领域的研究，都指出了这些方法的缺点和局限性。我们还提出了未来耳木耳多糖的研究方向; standardized processing methods must be confirmed, and officially approved 必须确认标准化的加工方法，并且商业应用需要官方批准的AAPs are needed for commercial applications. Finally, an optimistic outlook on the development of AAPs is given.。最后，对AAP的发展给出了乐观的展望。
