四种天然抗氧化剂：迷迭香提取物（ROS）的抗氧化活性。研究了60℃下葵花籽油中α -生育酚（TOC）、抗坏血酸棕榈酸酯（AP）和柠檬酸（CA）的抗氧化活性，其中，通过过氧化值和茴香胺值测定，迷迭香提取物（ROS.CON）具有最佳的抗氧化活性。α -生育酚对葵花籽油的稳定性有促氧化作用。研究了α -生育酚（TOC）、抗坏血酸棕榈酸酯（AP）和柠檬酸（CA）对迷迭香提取物（ROS.CON）的协同作用。迷迭香提取物与柠檬酸，特别是与抗坏血酸棕榈酸酯配用时，表现出加性抗氧化作用，与α -生育酚配用时，表现出负增效作用。(C) 2000 Elsevier Science Ltd.版权所有。
The antioxidative activities of four natural antioxidants: rosemary extract (ROS.CON), alpha-tocopherol (TOC), ascorbyl palmitate (AP) and citric acid (CA) were studied in sunflower oil stored at 60 degrees C. Among them, rosemary extract (ROS.CON) exhibited the best antioxidative activity, as determined by peroxide and anisidine value measurements. alpha-Tocopherol showed a prooxidative effect on stability of sunflower oil at tested conditions. The synergistic effects of alpha-tocopherol (TOC), ascorbyl palmitate (AP) and citric acid (CA) on rosemary extract (ROS.CON) were investigated. When combined with citric acid and especially ascorbyl palmitate, the rosemary extract showed an additive antioxidative effect, while by mixture with alpha-tocopherol a negative synergism was observed.
