It has been reported by Yildirim et al and
Siddhuraju et al [33, 34] that the reducing power of
bioactive compounds is associated with antioxidant
activity. Thus, it is necessary to determine the reducing
power of phenolic constituents to elucidate the
relationship between their antioxidant effects and there
reducing power [35]. The reducing power of the extracts
increases with an increase in the amount of the extract
as shown in Fig. 2. The amount of the phenolic
compounds was high in ethanol extract of fenugreek,
therefore; similar results were obtained in reducing
power activities. Hence, by correlating these results; we
can suggest that there may be relationship between the
amount of total phenolic content and reducing power.
