Antioxidant activity of methanol extract from Russula alatoreticula
| Antioxidant assays | Methanol extract | Standard |
|---|---|---|
| EC50 (µg/ml) | ||
| Scavenging ability of superoxide radical | 1940 ± 263a | 34 ± 1b |
| Scavenging activity of DPPH radical | 1083 ± 23a | 4.3 ± 0.3b |
| Chelating ability of ferrous ion | 263 ± 9a | 2.54 ± 0.59b |
| Reducing power | 2382 ± 23a | 14.5 ± 5b |
| Total antioxidant capacity (µg ascorbic acid equivalent/mg of extract) | 0.62 ± 0.03 | NA |
Ascorbic acid was used for comparison in all assays except chelating ability of ferrous ion method where EDTA was adopted as a positive control. In each row, different letters mean significant differences between sample and standard (P < 0.05)
