In the article titled “Antioxidant Effect of Polygonatum sibiricum Polysaccharides in D-Galactose-Induced Heart Aging Mice” [1], there is an error in Figure 3 where Figure 3(d) is incorrectly duplicated with Figure 3(c) due to an error in the production process. Additionally, in the legend of Figure 3, “The contents of MDA and ROS in the myocardium” should be corrected to “The contents of MDA and SOD in the myocardium”. The authors confirm that this does not affect the results or conclusions of the article, and the corrected figure and legend are as follows.
