Sulfated oligosaccharide zinc and preparation method thereof

The invention relates to sulfated oligosaccharide zinc and a preparation method thereof. The sulfated oligosaccharide zinc is prepared by taking dried frond of muriculate eucheuma as a raw material through process links of carrying out alkali treatment, extracting sulfated polysaccharide, preparing sulfated polysaccharide powder, preparing sulfated oligosaccharide powder, carrying out zinc impregnation, carrying out three-grade ultrafiltration separation, vacuum concentration, spray drying and the like. The sulfated oligosaccharide zinc prepared by the preparation method provided by the invention has high zinc content and relatively high content of sulfate groups, so that the sulfated oligosaccharide zinc has good physiological activity. The sulfated oligosaccharide zinc and the preparation method thereof have the advantages that the technology is advanced and reasonable, a processing process has strong controllability and expected economic benefits are good. 本发明涉及种硫酸寡糖锌及其制备方法，是以干燥的麒麟菜为原料，经碱处理、提取硫酸多糖、制备硫酸多糖粉、
