Abstract:The Camellia oleifera seed cake（CSC），a by-product after oil extraction from C. oleifera seed，is rich in active components including tea saponin，polysaccharides，protein，polyphenols. Therefore，its application value makes it a high-quality resource produced in the production of C.oleifera seed oil.The rapid development of the C. oleifera seed oil industry has brought a continuous surge in the output of CSC，promoting the rationalization and high-value application of CSC to be the concern.In recent years，the research on the extraction process，chemical composition，and comprehensive utilization of CSC has been deepened，and it has been gradually applied in fields related to feed，food，medicine，the chemical industry，and organic fertilizer，with an especially high application potential in the fields of functional food and medicine. The research progress of chemical composition，extraction process，and utilization methods of CSC were reviewed in this paper to provide a reference for further research and utilization of CSC.
