Phytochemicals and Antioxidant Activities

The crude polysaccharide (PMTP) was isolated from Polygonum Multiflorum Thunb through hot water extraction followed by ethanol precipitation. Through antioxidant assay in vitro, the results exhibited PMTP has powerful scavenging abilities, especially on ABTS, DPPH and Hydroxyl radicals. Therefore, the crude polysaccharide from P. Multiflorum Thunb should be explored as a novel potential antioxidant.
