A FUCOXANTHIN AND FUCOIDAN EXTRACTION METHOD FROM

The present invention relates to a method for extracting fucoxanthin and fucoidan from seaweed. The method of the present invention comprises: a first step of pulverizing seaweed; a second step of wrapping the pulverized seaweed in a non-woven fabric; a third step of inserting ethanol into the seaweed to perform room-temperature extraction; a fourth step of extracting the extract from the third step at a temperature of 50 to 60°C; a fifth step of extracting fucoxanthin from a filtered solution in the extract from the fourth step; and a sixth step of extracting fucoidan from the residual seaweed in the extract from the fourth step.
