The invention provides a method and device for fractionizing a biomass based on lignocellulose. The method comprises the following steps: providing the biomass based on lignocellulose and extracting the lignocellulose from the biomass by adding a first solvent dissolving in the lignocellulose; extracting xylose from the processed biomass by adding a second solvent capable of dissolving hemicellulose; and extracting the cellulose residued in the biomass. The method can perform continuous technology to replace the low-efficiency batch technology and obtain the components of the biomass at high yield.
