Abstract: Camellia oil was used as raw material to extract unsaponifiable matter (USM) by saponification-hexane extraction method.The compositions of USM in camellia oil were analyzed by gas chromatography-mass spectrometry (GC-MS),and DPPH radical-scavenging assay,ferric reducing-antioxidant power (FRAP) test and cellular antioxidant activity assay (CAA) were applied to determine their antioxidant activity in comparison with α-tocopherol.Results indicate that the compositions of USM in camellia oil obtained by saponification-hexane extraction are mainly hydrocarbon,triterpene alcohol and phytosterol.The DPPH free radical scavenging rate of USM in camellia oil is 95%,and the EC50 is 1.9 g/L.USM in camellia oil has certain ability to reduce Fe3+,and the FRAP value is 170 at the mass concentration of 5 g/L.USM in camellia can enter the HSF cells and inhibit the ABAP-induced intracellular reactive oxygen species formation.The CAA value is up to 36.6,when the mass concentration of USM is 100 mg/L.

Key words: cosmetic raw material, camellia oil, unsaponifiable matter, antioxidation
