as the concentration of the extract is increased (r2=
0.995, Figure 1) with maximum increase was observed
at 200 μg/mL. The reductive capacity of a compound
depends on the presence of reductones, which
have been exhibited anti oxidative potential by breaking
the free radical chain, donating a hydrogen atom.
Thus, reducing activity leads to termination of the radical
chain reactions that may otherwise be very damaging36.
The presence of reductants in the P. emblica
causes the reduction of the Fe3+/ferricyanide complex
to the ferrous form, indicating that polyphenolic extract
of P. emblica showed significant activities in
reducing power. Li et al.37 had reported the existence
of similar linear co-relationship between reducing
power and total phenolic content (TPC).
