A high absorbance indicates high reducing power (RP). The RP of the extracts increased
with increase in concentration. BHT showed maximum RP
followed by the FRB, CDRB and LDRB. The reducing
power of a compound is related to its electron transfer
ability and may therefore serve as a significant indicator of
its potential antioxidant activity Yildirim et al. (2003).
Literature reports are evident that the reducing power of
bioactive compounds is associated with antioxidant activity
Dorman and Peltoketo (2003).
