(57) Abstract: [PROBLEMS] To provide a composition which enables sustained release of a biologically active substance and mixing of the biologically active substance which is incompatible. A composition containing a crosslinked product derived from a water-soluble polysaccharide and a biologically active substance, preferably a biologically active substance in the crosslinked product derived from a water-soluble polysaccharide. Retained microcapsules, a method for producing the microcapsules, and a pharmaceutical, fertilizer or agrochemical composition containing the microcapsules. [Effect] The composition of the present invention incorporates a biologically active substance with high efficiency and has an excellent sustained release effect. Further, the composition of the present invention does not need to use an organic solvent, It can be manufactured by a simple and safe method. Furthermore, By incorporating one of the biologically active substances having a contraindication in the microcapsule of the present invention, A mixed preparation of the biologically active substance can be provided. |
