[Study on industrialized extraction technology and function of hyperlipidemic regulating of Laminaria japonica polysaccharides].

OBJECTIVE: To study the industrialized extraction technology and the function of hyperlipidemic regulating of Laminaria japonica polysaccharides. METHODS: With the orthogonal design L9 (3(4)), different influential elements of the industrialized extraction technology of Laminaria japonica polysaccharides were investigated. Mice treated with different doses of polysaccharides were applied to investigate its-function of hyperlipidemic regulating for 15 days. RESULTS: 5% Na2CO3, 3 hours and 80 degrees C was the best extraction condition, and the extraction rate was 2.13%. Different groups of polysaccharides with different levels of purity and dose lowered the TG, TC level of the mice in various degree. CONCLUSION: Laminaria japonica polysaccharides have obvious effect on hyperlipidemic regulating.
