Elected Academician of the International Eurasian Academy of Sciences in 2020, Professor Peixue Ling is a distinguished Chinese pharmaceutical scientist whose research and professional work have focused on polysaccharide-based biopharmaceuticals, particularly hyaluronic acid (HA, also known as sodium hyaluronate). Born in 1963, he has devoted more than three decades to the research, technological development, and industrial application of HA raw materials, formulations, and biomedical materials. His work has encompassed the development of HA production technologies, pharmaceutical formulations, and biomedical applications. He established a high-viscosity fermentation precision-control and continuous purification and refining system for large-scale HA production, integrating separation, precipitation, and drying into an integrated process. He developed seven pharmaceutical raw materials and contributed to the development of more than ten products that obtained national Class II new drug certificates. He also participated in the formulation of the United States Pharmacopeia standard for HA and contributed to the development of a large-scale HA raw-material production base with an annual output of approximately 300 tonnes and a broad product range.
