of silver nanoparticles could be the reason
for bactericidal activity of G. mangostana
reduced silver nanoparticles
The antioxidant activity of G. mangostana
fruit extracts and biosynthesized AgNPs
was evaluated by using DPPH scavenging
assay. As shown in (Figure 5), a
significant difference was observed among
the respective values obtained. The DPPH
values were increased in a dose dependent
manner. The recorded value for the lowest
concentration of the aqueous extract (20
g/mL) was 22.33 ± 0.33 and this value
was significantly increased to 71 ± 0.58, in
higher concentration
