Abstract
The present research aim
ed to quantify the total flavonoid content and antioxidant properties
in the different crude extract of the stem of Solanum nigrum that grow in southern Al geria.
The results showed that EtOAc extract showed the highest flavonoid content ( 18.41 0.023
mg Q E/g). The electrochemical behavior of the chloroform , ethyl acetate and n butanol
extracts were studied and indicated that a ll extracts were elec troactive a nd possess antioxi dant
activity, chloroform extract showed the highest capacity ( 9.58 0.010 mg/g it has b een
shown that these samples showed scavenging ability on superoxide anion produced by
electrochemical reduction of oxygen. T he chlorofo rm extract was t he most efficient extract
presenting the lowest I C 50 values (0.664 mg/ The bindin g cons tant (K b ) of the reaction
and the change in free energy (ΔG) were calculated.
