potential natural antioxidant not found in land plants [35].
Sulfated polysaccharides from marine algae are known to
exhibit many biological and physiological activities, including
anticoagulant, anti-hyperlipidemic, antiviral, anti-tumor
and antioxidant activities [36-39]. Previous studies have indicated
that the polysaccharide bioactivities depend on the
degree and position of sulfation [40-41]. The protein content of
the S. sargassum sulfated polysaccharide was (0.66 ± 0.81) %.
This is similar to the results of Tatiana et al [42] which showed
that the protein content of the polysaccharide from brown
seaweed Fucus evanescens was less than 2%. Local variation
in salinity has also shown to be an important factor in the
biological uptake of a number of elements [43-44].
