Polyphenols are valuable plant constituents for the
scavenging of free radicals because of their phenolic
hydroxyl groups [49]. This, together with the obtained
results,suggeststhat asthe amount of polyphenolic compounds
increases, the antioxidant activity also increases.
In conclusion, the present study demonstrates that the
polyphenolic extract of T. chebula fruits can protect the
body from oxidative stress from ROS, which may be
due to the phyto-chemicals in the form of polyphenols
that occur in the plant. These may be used in nutraceuticals
and the food industry. However, additional studies
are necessary to develop a method for the fractionation
and identification of polyphenols and to determine the
most active antioxidant compounds in the polyphenolic
extract.
