Table 4 Antioxidant activity of the methanol extracts obtained from dried powder formulations of three Tuber species from China

From: Nutritional value, chemical composition and antioxidant activity of three Tuber species from China

Antioxidant properties Assay EC50 value (mg/mL)
T. latisporum T. subglobosum T. pseudohimalayense
Reducing power Ferrous ion-chelating 0.82 ± 0.07c 1.50 ± 0.08b 1.92 ± 0.13a
Ferricyanide/Prussian blue 12.95 ± 0.03c 13.69 ± 0.12b 20.02 ± 0.10a
Radical scavenging DPPH 6.94 ± 0.15b 7.87 ± 0.15a 6.03 ± 0.26c
Hydroxyl radical 1.29 ± 0.03a 1.32 ± 0.04a 1.11 ± 0.04b
  1. The results are presented in EC50 values, meaning that higher values correspond to lower reducing power, radical scavenging activity. EC50 is the concentration of the extract that corresponds to 50% of antioxidant activity for the ferrous ion-chelating, DPPH, hydroxy, and or 0.5 of absorbance for the ferricyanide/Prussian blue assays
  2. a,b,cIn each row, the different letters represent significant differences between samples (p < 0.05)
