Extracts | TPC (mg GAE/g of extract) | IC50 on DPPH radical (mg/ml) |
---|---|---|
Hexane | 9.600 ± 0.014 | 0.366 |
Ethyl acetate | 23.800 ± 0.058 | 0.326 |
Chloroform-ethanol (1/1) | 40.500 ± 0.041 | 0.274 |
Butanol | 16.900 ± 0.039 | 0.635 |
Water | 2.072 ± 0.002 | >1 |
BHT | - | 69 10-3 |
α-tocopherol | - | 7.5 10-3 |
IC50 values on DPPH were calculated from the plot of the scavenging effect against the extract concentration. Effects of BHT and α-tocopherol, used as standard, were measured in the same conditions. All experiments were performed in triplicate ± standard deviation
