摘要: 利用DPPH法[1]对四种黄酮类食用天然色素的研究发现:它们都具有抗氧活性,有的可与BHT相比美。从紫外光谱和黄酮含量的分析说明了四种色素的抗氧活性与黄酮化合物含量及结构的关系。为进一步拓宽黄酮类食用天然色素的应用,提供科学依据。

Abstract: The four natural edible flavonoid pigmets were studide by DPPH. The results indicated that they all have had the antioxidant activities and some of them were the same as BHT. The analyses from ultraviolet spectrum and contents of the flavonoid confirmed the close relationship between the antioxidant activities of the four pigments and the contents and structures of the flavonoid. The present study provided the scientific basis for further developing the application of natural edible flavonoid pigments.
