| Abstract: |
| The effects of refining process on the bioactive constituents and antioxidant activity of oil-tea camellia seed oil were studied. The results showed that the contents of bioactive constituents in oil-tea camellia seed oil reduced continuously during refining. After alkali refining，the loss rate of polyphenols reached 80.50%；after bleaching and deodorization，the loss rates of tocopherol reached 13.05% and 20.69% respectively，and the loss rates of sterols reached 12.85% and 13.09% respectively；the loss rate of squalene reached 24.99% after bleaching. In terms of antioxidant activity，there were some differences in the scavenging capacities of oil-tea camellia seed oil on three free radicals，and the scavenging rate on ORAC free radical was the highest，followed by ABTS free radical and DPPH free radical. |
