| titleOfInvention | Extraction method and application of fucoidin |
| abstract | The invention belongs to the technical field of polysaccharide extraction, and particularly relates to an extraction method of fucoidan and application thereof. The method comprises crude extraction and purification, wherein the crude extraction process comprises the steps of crushing raw materials, soaking and extracting with acetic acid aqueous solution, filtering, retaining filtrate, heating filter cakes in the acetic acid aqueous solution to 30-40 ℃, stirring and extracting for two times, filtering, combining the two filtrates, adjusting to be neutral, further adding ethyl acetate for extraction, extracting pigment from an organic layer, and precipitating a separated water layer with ethanol to obtain a crude extract of fucoidan. The technical scheme provided by the invention avoids the damage of fucoidan to the maximum extent under the conditions of mild temperature and pH value in the crude extraction stage, has higher sulfate content, and extracts fat-soluble and particularly pigment substances in the crude extraction stage, so that the operation not only improves the yield of fucoidan, but also provides possibility for the recycling of fucoxanthin, and increases the comprehensive utilization rate of raw materials. |
