Figure 2

Analysis of the antioxidant capacities of the aqueous extracts of P. mume unripe flesh (PmUF), ripe flesh (PmRF), and ripe seed (PmRS). (a–c) Measurement of antioxidant potentials. DPPH assay (a), ferric reducing/antioxidant power assay (b), and cupric ion reducing antioxidant capacity assay (c) were performed to measure the antioxidant capacities of the extracts. (d, e) Determination of total phenol content and total flavonoid content. Total phenol content (d) and total flavonoid content (e) were also measured, as described in detail in the Materials and Methods section.
