As natural antioxidants, such polysaccharides offer advantages over synthetic counterparts in mitigating ROS\u2010related diseases. Their antioxidant depends on structural features, yet Xinjiang apricot polysaccharides remain poorly characterized. This study employs ultrasound\u2010assisted enzymatic extraction, DEAE\u201052 purification, and multitechnique structural analysis to investigate these polysaccharides, aiming to establish their structure\u2013activity relationship for potential functional food or therapeutic applications.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In this study, a galacturonic acid\u2010rich heteropolysaccharide (UEDAP\u20104) was successfully extracted and isolated from dried apricots from Xinjiang, China. The polysaccharide is primarily composed of five monosaccharides: arabinose (Ara), rhamnose (Rha), galactose (Gal), glucose (Glc), and galacturonic acid (GalA), with a molar ratio of 28.78:20.36:6.87:5.51:38.48.
