Assessment of contents of total polyphenols (TP) and antioxidant capacity by the methods of the phosphomolybdenum complex (RAC) and DPPH-radical scavenging (IC50).
| Sample | TP (%)±s.d. (RSD%) | RAC±s.d. (RSD%) | IC50 (µg/ml)±s.d. (RSD%) |
|---|---|---|---|
| AqE | 36.47±0.18 (0.51) | 0.46±0.01 (0.96) | 9.59±0.04 (0.41) |
| EBPC | 55.95±1.12 (2.01) | 0.69±0.03 (4.15)* | 6.67±0.05 (0.82) |
| EPA | 65.80±0.62 (0.93) | 0.75±0.01 (1.75)* | 5.23±0.08 (1.49)** |
| EPB | 22.1±0.37 (1.64) | 0.36±0.02 (5.20) | 14.97±0.15 (1.01) |
| Vitamin C | 1.00 | 4.93±0.05 (1.07) |
RAC = relative antioxidant capacity; IC50= amount of antioxidant necessary to decrease the concentration of the DPPH radical by 50%; s.d.= standard deviation; RSD= relative standard deviation. ANOVA, *P<0.01; **P<0.05 in relation to vitamin C.
