Abstract: In this paper, the preparation methods, immunomodulatory functions and applications of placenta extracts in life and production are introduced. The placenta extracts have immunomodulatory, anti-oxidative, anti-neoplastic and nutritional functions. The preparation methods of placenta extracts mainly include ultra-filtration method, enzymatic hydrolysis method and microbial fermentation method. Each method has its advantages and disadvantages. Accordingly, when choosing the preparation method of placenta extracts, comprehensive consideration should be taken according to the own conditions and requirements as well as previous experience. In the aspect of skin care, placenta extracts can be added as an antioxidant component to skin care products to delay skin aging. In terms of disease treatment, placenta extracts can improve the clinical symptoms and liver function of patients with hepatitis, have a negative regulatory effect on the proliferation of pancreatic cancer cells, show a certain therapeutic effect on hypersensitivity, and exhibit a significant effect in nerve regeneration. Placenta extracts have broad application prospects in research and development of health care products, skin care products as well as in disease treatment.
