In this paper,methanol was used as solvent to extract polyphenols from seeds of camellia oliefera, and the antioxidant activity of potyphenols of camellia seeds extract to camellia oil was identified. The results indicated that polyphenols from seeds of camellia oliefera had remarkable oxidative stability. Monoglyceride was a kind of ideal emulsifier in potyphenols and camellia oil mixture, and it could improve antioxidant activity of polyphenols. Antioxidant activity of polyphenols could be improved with more addition of extract. Antioxidant activity of polyphenols was not as good as BHT.But ...
