3.4. In vitro antioxidative effect of the extract against hydrogen
peroxide
The extract showed an inhibitory effect against hydrogen
peroxide in a concentration-dependent manner (Fig. 3). H2O2 was
incubated with 6 different extracts at the mean concentration of
9.5 0.4 nmol of H2O2 mL1 of reaction mixture. The H2O2 inhibition
by E was statistically significant from 37.5 mg of proteins
mL1 (p ¼ 0.05). This inhibition was still significant at the 1% level
from the protein concentration of 62 mg mL1
.
