Abstract: Flammulina velutipes polysaccharides have many health benefits for human being, making it a magnificent value for development. Flammulina velutipe offcuts are low-cost and can be extracted with polysaccharide and activated carbon. This experiment in primary studies extracting polysaccharide and a process of preparation of activated carbon from flammulina velutipe cutoffs by using hot water. Through single-factor and SAS optimization design, an optimal condition of having polysaccharide is obtained: an extraction temperature of 100 ℃, a pH of 5.9, a solid-liquid ratio of 1:15 and a leaching period of 3.47 h. The polysaccharide extraction yield acquired is 42.65 mg/g which has 3.8 times increase in comparison to the last optimization; With single factor optimization, the optimum condition of using microwave carbonization to prepare activated carbon is achieved: 50% phosphoric in activation for 8 hours, medium baking and carbonization for 5 min. the achieved activated carbon has a capacity of adsorbing methylene in 81.22 mg/g, with an adsorption rate of 95.33%. This study provides theoretical basis and technical supports for Flammulina velutipe cutoff resource development.Keywords: Flammulina velutipe cutoffs, Flammulina velutipe polysaccharide, activated carbon, extraction

This experiment take asparagus off icinalis Linn the flower bud as a material, uses theparaffin wax 切片法 movie-making, observedasparagus off icinalis Linn the floweredmedicine dissection structure, the comparative analysis asparagus off icinalis Linn flower bud exterior shape characteristic as well as the paraffinsection observation, obtains between the two to correspond therelations; Take asparagus off icinalis Linn the flowered medicine as the material,carries on the flowered medicine raise to obtain suits asparagus off icinalis Linn theflowered medicine raise induction culture medium, the split up culturemedium and the raise condition and obtains the pollen adult plant;Carry on the peroxide enzyme same labor enzyme electricity byasparagus off icinalis Linn the regeneration adult plant and the cultivation adult plantto swim the distinction regeneration adult plant's sex, its resultindicated. 1.asparagus off icinalis Linn the flower bud transverse cutting delivers in person thebutterfly the shape, separates, the constitution by themedicine. including , flowered medicine wall twoparts. The colored medicine wall initial period often stores themassive matter. When the colored medicine is mature, the cell radialdirection expands, stores the matter to vanish, besides to thewall, has the multi- strip slanting longitudinal stripe shapecellulose the center fabric cell isbigger, the initial period but starts for the single nucleus in thepollen mother cell to reduce time the fission, forms orpolynuclear. struggles generation surprised toadmirefresh emperor S slanting postscript Song respectfully? 2. different growth times asparagus off icinalis Linn flower bud material exterior shapecharacteristic as well as between the flowered medicine interiorcytology characteristic, obtains between the two to correspond therelations. When flower bud length 1.5-2mm the flowered medicine is inthe single nucleus to keep to the side the time. 3.
