| الوصف: | The ethanol extraction method was used to extract fucoidan from the sample of Undaria pinnatifida collected from sea of Weihai, Shandong province, China.The ethanol extraction method was used to extract fucoidan from the samples.Low molecular weight fucoidan isolates with molecular weight less than 1×10 4 u were prepared by dialysis method.The sulfates, uronic acids, and their scavenging abilities on 1,1-diphenyl-2-picrylhydrazyl (DPPH) and on hydroxyl radicals of fucoidans with different molecular weight were determined respectively.The physical and chemical constituents and antioxidant activities of the fucoidan crude extracts and fucoidans with molecular weight less than 1×10 4 u were analyzed and compared.The results showed that the sulfate and uronic acid content of the crude extract was slightly higher than that of low molecular weight fucoidan, and the sulfate mass fraction of the crude extracts was as high as 36.50%.Compared with the crude extracts, the fucoidan of low molecular weight has higher primary and secondary antioxidant capacity. |
