Antioxidant potential of herbal polysaccharides: An overview on recent researches

Abstract

Since past few years, a number of polysaccharides are being extracted from different herbal sources, which have already been investigated for biomedical activities. Nowadays, antioxidant activities of numerous herbal polysaccharides are being extensively researched and it becomes a hot spot in the field of biomedicine research. During past few decades, many herbal polysaccharides have been investigated to fulfill the purpose of raising their uses for antioxidant activity with removing free radicals and inhibiting lipid peroxidation, protecting biofilms, and anti-aging effects. The methods of extractions and their benefits and drawbacks, different types of in vitro antioxidant assay, factors affecting the antioxidant activity of bioactive polysaccharides and recent studies on bioactive polysaccharides from herbal sources with their antioxidant activities has been discussed in this review.
