Galunhui November 7th | Xiamen Kingdomway Group (002626.SZ) announced that its holding subsidiary Jiangsu Chengxin Pharmaceutical Co., Ltd. and its wholly-owned subsidiary Xiamen Kingdomway Biotechnology (Jiangsu) Co., Ltd. recently received a patent certificate for an invention issued by the National Intellectual Property Office. The invention is titled a method for preparing a complex of L-muscle zinc peptides.

This invention provides a method for preparing a complex of L-muscle zinc peptides. In the complexation reaction stage of the preparation method, the addition of water is not required, using a water-free solvent system reduces the difficulty of purification of the product. After solid-liquid separation, the residual solvent in the wet product is small, reducing the difficulty of later granulation, which has high practical value for the industrial production of L-muscle zinc complexes.
