The invention discloses a
biomass composition capable of forming and slowly releasing short-molecular
polysaccharide, a preparation method and a preparation of the
biomass composition. The
biomass composition capable of forming and slowly releasing short-molecular
polysaccharide comprises the following components in part by weight: 50-300 parts of Poria cocos and 20-80 parts of acidic material. The preparation method of the
biomass composition comprises steps of pretreatment, blending, sterilization and split charging, in particular comprises the following steps: removing impurities from Poria cocos, rinsing and
cutting Poria cocos, and performing
superfine grinding to Poria cocos for future use; adding the superfine ground acidic material into the treated Poria cocos, mixing the acidic material and Poria cocos uniformly to obtain the target composition; and sterilizing the target composition and carrying out split charging. The preparation of the
biomass composition is a
powder, a
capsule, a granule, a tablet or a
pill prepared by adding a pharmaceutically acceptable auxiliary material into the slow-release
drug with short-molecular
polysaccharide. The
biomass composition is simple in manufacturing process, convenient to operate, low in cost, convenient to take, high in absorptivity and long in timeliness.
