According to all tested methods, the antioxidant activity of all
palm dates syrups was compared with that of Vit. C, which is a
well known potent antioxidant. In general, the present study
reports that palm dates syrups can be a good source of natural
antioxidants, which act by several mechanisms, such as
removal of free radicals, scavengers of
NO,
OH, and H2O2,
chelation of Fe2+ ion, the ability to reduce transition metals
(i.e., Fe3+ fi Fe2+), and the ability to prevent lipid peroxidation.
However, on the bases of used methods, the antioxidant
efficiency of syrups can be arranged as follows: Rotab syrup
> Saudi syrup > Iraqi syrup. This arrangement could be
attributed to their significant differences in the contents of
total phenolic and total flavonoids. The scientific results
obtained from this study signify that the palm date fruits (or
their syrups) are very important source of natural antioxidants, which can play a very important role in reducing oxidative
stress and preventing from dangerous diseases, such as
cancer, liver, and cardiovascular diseases. In addition, the
new data support the folk medicine, which uses palm date
fruits for treatment of liver diseases. However, according to
the new results, the Rotab-palm dates are highly recommended
to be consumed in comparison with Tamr-palm dates. Due to
the importance of these data, this work is going to be extended
in vivo to evaluate the hepatoprotective and antioxidative
properties.
