* Maximum activity of all WSCGDs was determined at the same concentration of 10 mg/mL. ND: not detected. The letters a, b, c, d, e in the same column represent the statistical difference of means with p < 0.05 using Tukey-test. All data points in the table are mean and standard deviation. The anti-oxidant activity assay was conducted at 20 °C for 20 min.
