| Polyphenols were extracted from crude and refined oils from Camellia oleifera Abel. seed and Camellia polyodonta How. seed in Ya an by 80% ethanol, and the antioxidant activities of the polyphenols in the four kinds of oil-tea camellia seed oils were compared. The results indicated that the polyphenols contents of crude Camellia oleifera Abel. seed oil, refined Camellia oleifera Abel. seed oil, crude Camellia polyodonta How. seed oil and refined Camellia polyodonta How. seed oil were 1.41, 1.04, 0.75, 0.68 μg/mL respectively. The polyphenols in four kinds of oil-tea camellia seed oils showed strong antioxidant activities, and the antioxidant activities enhanced with polyphenols contents increasing; the antioxidant activity of polyphenols extracted from Camellia oleifera Abel. seed oil was stronger than that from Camellia polyodonta How. seed oil; crude oil had stronger antioxidant activity than refined oil; the antioxidant activity of polyphenols in crude Camellia oleifera Abel. seed oil was unstable. |
