Fig. 1 Antioxidative activities
of different brown lead seed
extracts using various
extraction solvents as
determined by DPPH radical
scavenging (a), ABTS radical
scavenging (b), FRAP (c) and
metal chelating (d) assays. The
extracts with a concentration of
3.6 mg/ml were used for
activity assays. Bars represent
the standard deviation (n03).
Different letters on the bars
