L. is a tropical deciduous tree producing edible berries with potential medicinal value. In this study, a novel water-soluble phyllanthus emblica polysaccharide (PEP) from the berries was isolated by precipitation and purification, and analyzed for its structure features. The results showed that PEP was aα-pyran acidic heteropolysaccharide with a molecular weight of 1.31 × 10 Da, which included galacturonic acid, galactose, rhamnose, and arabinose with a molar ratio of 3.21:6.59:1:0.23. Furthermore, the antioxidant activities of PEP were determined and showed remarkable antioxidant capacities in DPPH, superoxide anion- and hydroxyl-radical scavenging, ferric-reducing antioxidant power, and lipid peroxidation inhibition. This work indicated that PEP as a natural antioxidant agent from the berries ofL. had potential application for developing valuable nutraceutical in food industry.
