| 摘 要： | 以猪油为底物 ,采用Na2 S2 O3 I2 滴定法测定了月季花提取物的抗氧化活性。结果表明 :月季花95 %乙醇粗提物对猪油的抗氧化作用最强 ,其抗氧化作用随提取物浓度增加而逐渐增强。柠檬酸、半胱氨酸等对月季花提取物具有协同抗氧化作用。特别是抗坏血酸、维生素E与提取物复配 ,具有显著的协同抗氧化作用 ,复合物的抗氧化性优于茶多酚 ,几乎可与特丁基对苯二酚相媲美

| Abstract: | The antioxidative effect of extracts from Chinese rose was measured with Na2S2O3-I2 titrimetric method by using lard as substrates. It was found that the antioxidative activities of the Chinese rose extracts retrieved by 95% ethanol solution were the highest, and the activities were strengthened with the increase of dosage. Citric acid and amino acid showed synergistic effects in antioxidative activities with extracts of Chinese rose. Ascorbic acid and alpha-tocophrol also showed strong synergistic antioxidative effect with the extracts of Chinese rose. The combined antioxidative activities were higher than the activity of tea polyphenols, and almost as good as that of tertiary butyl P-dihydroxy bengene(TBHQ). |
