Objective To investigate the antioxidant activity and hypolipidemic function of camellia seed oil, bitter apricot kernel oil, and peanut oil.Methods The antioxidant and hypolipidemic activities of the three oils are evaluated through in vitro antioxidant tests and in vitro hypolipemic tests.Results The order of DPPH free radical scavenging capacity is camellia seed oil>bitter apricot kernel oil>peanut oil. The order of superoxide anion free radical scavenging capacity is camellia seed oil>bitter apricot kernel oil>peanut oil. Additionally, the order of hydroxyl free radical scavenging capacity is camellia seed oil>bitter apricot kernel oil>peanut oil. At a mass concentration of 1 mg/mL, the binding rates of each oil to taurocholate and glycocholate are listed below: 6.72% and 56.14%, respectively, for camellia seed oil, 45.73% and 52.87%, respectively, for bitter apricot kernel oil, and 43.67% and 55.23%, respectively, for peanut oil.Conclusion In vitro antioxidant and hypolipidemic effects are the best in camellia seed oil, which could be further developed and utilized.
