Study on antioxidant activity of mussel enzymatic peptides
Abstract: This article uses mussel as materials, it is an important aquaculture species worldwide, the ratio of Mytilus edulis (ME) is the largest. But people could not make more profits if only mussel was sold directly. Mussel not only is a traditional tonic food, but also has a high nutritional value and variety of pharmacological effects. According to related materials, both mussel and its extracts have variety of functional effects, such as anti-oxidant, immune regulation, anti-tumor, antihypertensive effect and so on. Polysaccharides are one of the major chemical ingredients of ME. And now more researches were focused on the crude polysaccharides from ME, however, the studies about the extractions, purifications and structures and functional researched systemly have not yet reported. Therefore, ME were obtained from an island named wolfberry in Zhoushan and then employed to extract polysaccharides. Extraction, isolation, structure identification and bioactivity of polysaccharides from ME were further studied. The major results obtained in this study were as follows: In DPPH radical and restore the power system and hydroxyl radical and super oxygen radical system, with sample the concentration of whom we shall solve the enzyme antioxidant activity enhance.
