紫外辐射对红枣色素抗氧化活性的影响
Effects of ultraviolet radiation on antioxidant activity of jujube pigment
摘要
Abstract
In order to explore the effects of ultraviolet radiation on the antioxidant activity of jujube pigment,the contents of total polyphenols,anthocyanins and total flavonoids in jujube pigment were measured,and the scavenging capacity of DPPH·,· OH,O2-· and reducing power were determined,the effects of ultraviolet radiation on the antioxidant active components and the antioxidant activity of jujube pigment were evaluated,and the correlative relationships between the contents of active components and antioxidant activity in jujube pigment were analyzed.The results showed that ultraviolet radiation had obvious effects on antioxidant active components and the antioxidant activity of jujube pigments,with the extension of ultraviolet radiation time,the shortening of radiation distance,the contents of total polyphenols,anthocyanins,total flavonoids and the scavenging capacity of DPPH·,· OH,O2-· and reducing power of jujube pigment were decreased.The results of correlation study showed that total polyphenols and anthocyanin contents were highly correlated with antioxidant activity of jujube pigment,but the content of total flavonoids was weak correlated with antioxidant activity.It was indicated that ultraviolet radiation has a significant effect on the antioxidant activity of jujube pigment.关键词
