Anthocyanin‐rich mulberry extract improves vascular endothelial function in aging rats. (a) Level of NO was measured in rat serum of different experimental groups. Relative quantification of NO in serum. (b) DAF2DA fluorescence staining for NO levels in aortas. (c) Representative images of DHR staining for peroxynitrite in aortas and quantification of DHR fluorescence intensity for peroxynitrite levels in aortas. (d) Nitrotyrosine expression in the aortas was determined by immunofluorescence (n = 6, *p < 0.05 vs. the young group; #p < 0.05 vs. the aging group)
