DPPH radical–scavenging activities of EGCG and EGCG glycosides: EGCG-G1 (2) (100 μL of 4.04, 8.07, 16.13, 24.20, 241.95, 483.90, 873.60 μM), EGCG-G2 (3) (100 μL of 3.20, 6.39, 12.78, 19.17, 191.70, 383.40, 511.20 μM) or EGCG (100 μL of 5.46, 10.92, 21.84, 32.76, 327.60, 655.20, 870.4 μM) was mixed with 0.13 μM 1,1-diphenyl-2-picrylhydrazyl (100 μL) in darkness at room temperature for 30 min, and the absorbance was monitored at 519 nm. Each value is the mean ± standard deviation (n = 3).
