title: In vitro antioxidant activities of polysaccharides extracted from Moso Bamboo-Leaf.
abstract: The objective of this study was to evaluate in vitro antioxidant capacities of polysaccharides extracted from Moso Bamboo-Leaf (BLP). The molecular weight of the polysaccharides were obtained by SEC-LLS and their molecular masses were 13.4×10(4)Da, 2.8×10(4)Da and 1.9×10(4)Da, respectively. Available data obtained with in vitro models suggested WB1 (precipitated by 30% ethanol) showed significant inhibitory effects on superoxide radical, hydroxyl radical, DPPH radical and ferrous metal-chelating capacities. These results clearly establish the possibility that polysaccharides extracted from Moso Bamboo-Leaf could be effectively employed as ingredient in health or functional food, to alleviate oxidative stress.
