Note: Results were expressed as mean ± standard deviation, different superscript letters in each column represent significant differences (p < 0.05) in samples. Treatments: C: control, without antioxidant; VC: 0.025% sodium D-isoascorbate; T1 T2, T3, and T4: contained 0.06%, 0.12%, 0.18%, and 0.24% flavonoid extracts from C. paliurus, respectively.
