Abstract：fructus corni is a kind of contains a great deal of natural cellulose fiber raw material, the extraction and application of cellulose in fructus corni has certain economic benefits and ecological benefits.Based on fructus corni as raw material, by 1% NaOH preprocessing, dewaxing, fat, pectin, hemicellulose, microwave radiation heating lignin removal fructus corni cellulose.Anthrone colorimetry is adopted to improve the content of cellulose, and studied the performance of fructus corni cellulose, at the same time the use of fructus corni cellulose for the preparation of cellulose nitrate.The results show that the extract of fructus corni cellulose compared with microcrystalline cellulose slightly yellow;Anthrone colorimetry to detect the sample of the cellulose fiber content is relatively rich (2%);Cellulose is not soluble in water and common organic solvents, soluble in strong acid alkali concentration solution, etc.;Samples of cellulose in 70% - H2SO4 hydrolysate with silver mirror reaction of silver ammonia solution, and the new system of brick red precipitate reagent Lin formation;Preparation of cellulose nitrate after inspection found that the flammability is better, but after the sun change blue phenomenon.This paper adopted by the extraction of fructus corni cellulose method is simple and easy to operate, for the development and utilization of fructus corni waste, the method of this experiment of the preparation of cellulose nitrate is a mature industrial raw materials, nitrocellulose has developed since the advent of many areas, with the constant development of science and technology today, cellulose nitrate is expected to applied in more fields.
