Abstract： Camellia seed oil， asa vegetableoil rich in monounsaturated fatty acids，has attacted much attention due to its abundant bioactive components. β -resin alcohol is one of the main characteristic components in Camelia oleifera seed oil. In thisstudy， β -aromatic resin alcohols were chemically synthesized and the in vitro antioxidant activities of β -aromatic resin alcohols at five different concentrations （0.1，0.2，0.4，0.8mgmL-1 and 1.2mg⋅mL-1 ） were determined by spectrophotometry. The results show that β -resin alcohol can effectively eliminate reactive oxygen free radicals and exhibit a dose-dependent relationship，which can provide certain scientific basis for the development， application and industrial empowerment of Camellia oleifera seed oil.

Keywords： Camellia seed oil; β -amyrin;antioxidant
