Abstract:  The oil residues of Camellia semiserrata contain functional components such as tea saponin, flavonoids, polyphenols and polysaccharides with various biological activities. Current studies on tea saponin are focused on its isolation and identification. However, its structural identification remains a hot and difficult topic. Tea saponin is a nonionic surfactant and has many functions such as bacteriostasis, insecticidal action antioxidation, anti-inflammation and hemolytic effect. In this paper, the chemical structure, physical and chemical characteristics, surfactant property and biological activity of tea saponin are reviewed. 

Key words: oil residues of Camellia semiserrata, tea saponin, structure, biological activity
